What is hollow brick?

What raw materials do hollow bricks consist of

Hollow bricks are made of clay, shale, etc. as the main raw materials, after raw material treatment, molding, sintering.

The total area of holes in hollow bricks accounts for the percentage of the area of the brick where it is located, known as the pore rate of hollow bricks, generally should be more than 15%. Compared with solid bricks, hollow bricks can save a lot of land and brick-burning fuel, reduce the weight of transportation; reduce the labor intensity of brickmaking and masonry, accelerate construction progress; reduce the weight of the building, increase the number of floors, reduce costs.

Difference between porous and hollow bricks

Porous bricks are generally dense,

1\ both brick hole rate requirements are equal to or greater than 15%;

2\ porous bricks holes in the size of the small and the number of holes, the hollow brick hole size and the number of holes;

3\ porous bricks are commonly used in the load-bearing parts of the hollow bricks are commonly used in the non-load-bearing parts.

Block: The length, width or height of the main specification has one or more items greater than 365 mm, 2.0 mm or 115 mm respectively, but the height is not greater than six times the length or width, and the length is not more than three times the height.

What are the sizes of hollow bricks?

Non-load-bearing hollow brick:190*190*90 190*190*190 290*290*90

Load-bearing hollow brick:190*190*90 240*115*90 240*180*115

What is a common brick Refractory Brick Hollow Brick

Refractory bricks are referred to as fire bricks. Refractory material

Refractory bricks are fired with refractory clay or other refractory raw materials. Pale yellow or brownish. Mainly used for smelting furnace, can withstand high temperature of 1,580℃-1,770℃. Also called firebrick. Has a certain shape and size of the refractory material. According to the preparation process can be divided into fired bricks, non-fired bricks, electrofusion bricks (casting bricks), refractory heat-resistant bricks; according to the shape and size can be divided into standard bricks, ordinary bricks, special bricks and so on. Can be used as a building kiln and a variety of thermal equipment, high-temperature building materials and structural materials, and at high temperatures can withstand a variety of physical and chemical changes and mechanical effects. For example, refractory clay bricks, high alumina bricks, silica bricks, magnesium bricks and so on.

Hollow brick is divided into cement hollow brick, clay hollow brick, shale hollow brick. In March 2011, Yunnan Yingjiang 5.8 magnitude earthquake, the use of cement hollow brick houses collapsed, resulting in a number of deaths, due to safety hazards, Yunnan proposed to ban cement hollow brick, Shandong Qingdao, the building under construction has also called a halt to the use of cement hollow brick. Professionals in the construction industry have argued that the ban is unscientific and a layman's approach. It is misleading to the public and must be corrected. Hollow bricks are just a building material and there is nothing wrong with using them in a scientific way. The use of hollow bricks in the use of science is very strong, the quality requirements are also high, the investigation of the foundation is suitable for the use of hollow bricks, how to design, construction of cement and other related ingredients there is no problem, etc. are related. According to strict procedures for scientific use, strict implementation of relevant national standards for the use of qualified hollow brick, there is no problem. By the same token, if the use of solid bricks does not strictly enforce the relevant national standards, the same will be a problem.

Ordinary brick is our most common red brick, nothing special

What is the difference between hollow bricks and solid bricks

In order to protect the precious land resources, energy saving and energy saving emission reduction, to protect our living environment, the relevant state departments of the building industry construction ban on the use of ordinary clay sintered bricks of the ban, vigorously promote the use of hollow bricks.

1, hollow brick and solid brick compared to save a lot of land with soil and brick burning fuel, reduce the weight of transportation; light weight, concrete hollow block than red brick is about 1/3 lighter than the building weight can be reduced.

2, high compressive strength, in addition to suitable for all types of industrial and civil construction filler walls, but also as a load-bearing wall, especially solid concrete blocks. In some areas, often instead of red brick in the brick structure as a load-bearing wall.

3, sound insulation, heat insulation, moisture, fire, corrosion resistance and other properties.

Foreign buildings with hollow brick is more common, cut has long been detailed provisions. The ordinary hollow brick masonry structure of the building, there are strict building height restrictions. For example, in Japan, in the last century, it is stipulated that the ordinary brick, no reinforcement for the reinforcement of the building, the height of the floor is limited to less than 3 layers.

Are porous bricks and hollow bricks the same thing?

Porous bricks are generally dense,

1\ Both types of bricks are required to have a hole rate equal to or greater than 15%;

2\ Porous bricks have a small hole size and a large number of holes, while hollow bricks have a large hole size and a small number of holes;

3\ Porous bricks are commonly used in load-bearing parts, while hollow bricks are commonly used in non-load-bearing parts.

Block: The length, width or height of the main specification has one or more items greater than 365 mm, 240 mm or 115 mm respectively, but the height is not greater than six times the length or width, and the length is not more than three times the height.

What is the difference between hollow and solid bricks? Why does the country ban the use of solid bricks?

Hollow is good, almost the same strength and light weight.

In fact, the common bricks on the market now are divided into traditional red bricks and environmentally friendly lightweight bricks two categories.

Red bricks according to the quality of the soil, processing brick embryo, air drying, firing, divided into one class, two classes, three classes, inferior.

Lightweight bricks are divided into aerated lightweight bricks and Farilon lightweight bricks.

Lightweight bricks are slightly more expensive, but there are many advantages, a good brick type, the second material is light (density is lighter than water), the third is to support environmental protection and everyone's stomach.

Why advocate the use of hollow brick?

Hollow brick is light, high strength, thermal insulation, sound insulation and noise reduction performance. Environmental protection, no pollution, is the ideal filler material for frame structure buildings. The brick quality indicators, the test are in line with national standards

With hollow brick, because it is lighter, will not cause the floor to crack. In fact, there are many other partition wall materials, including light steel keel gypsum board, wire mesh, etc., both light, but also space-saving.

Generally like your home renovation brick wall should be used as a 1/2 brick wall, if you use hollow brick to do, the wall width and even stucco within 120 thick, the main advantage is the light weight is generally 95 brick wall 2/3, will not be too much burden on the structure of the house itself, the sound effect can be, because of hollow brick inside the holes in the arrangement of the sound insulation function considerations, relatively speaking, 95 brick wall thickness and hollow brick is the same as the wall. Body thickness and hollow brick is the same, since the important weight, sound insulation effect than hollow brick to be slightly better. But I suggest that the owner of the main brick wall is best to use concrete blocks, can achieve the best results!

MU10 hollow brick What is it

"MU10" hollow brick meaning: MU indicates the compressive strength level of sintered hollow brick. According to the national standard GB5101 (chapter 4 classification, article 4.2 grade), according to its compressive strength is divided into MU30, MU25.... MU10 five strength levels.

GB5101 Chapter 5 "in Article 5.3" Strength "in the provisions: M famine 10 average strength ≥ 10.0, strength standard value ≥ 6.5, the minimum strength of a single piece of ≥ 7.5.

Cement Hollow Brick is what?

Cement hollow brick is to cement as the main raw material, after raw material processing, molding, sintering and other types of technology and finally made of hollow brick. Cement hollow brick has the advantages of light weight, high strength, good heat preservation, sound insulation and noise reduction performance. Because of the light weight and high strength of the hollow brick, so the use of the building will not cause heavy pressure on the building wall, thus greatly reducing the probability of wall panels being cracked by heavy pressure. In addition, the use of cement hollow brick in the building can reduce the pressure of the wall on the ground, so that the air pressure inside the wall is the same as the outside air pressure, which in turn reduces the probability of building cracks to a certain extent. There is also because of the hollow brick brick body has holes, so compared to the solid brick sound insulation effect is better, to a certain extent, reduce the impact of noise. Another point is that the cement hollow brick compared to solid brick, has the advantages of environmental protection, pollution-free, is the ideal filler material for the frame structure of the building. However, the hollow brick has a fatal disadvantage, this disadvantage is also the cement hollow brick is called off one after another around the use of the reason - is the hollow brick) seismic performance is poor. Building experts said: in residential and other buildings in the construction process, the main load-bearing walls should be used to pour cement or solid bricks, etc.; other non-load-bearing walls can be used hollow bricks; walls and other non-residential buildings can be used hollow bricks.

What is a hollow brick wall?

Hollow brick is the main wall material commonly used in the construction industry in recent years, due to the advantages of light weight, less consumption of raw materials, has become the first recommended by the national building sector. As with red bricks, the common raw materials for hollow bricks are clay and cinder ash, and the general specification is 390×190×190mm.

Hollow bricks are made of clay, shale, and other raw materials, after raw material treatment, molding, and sintering. Hollow bricks of the total area of holes accounted for the percentage of the area of the brick in which it is located, known as the hole rate of hollow bricks, generally should be more than 15%. Hollow brick and solid brick compared to save a lot of land with soil and brick burning fuel, reduce the weight of transportation; reduce the labor intensity of brick making and masonry, accelerate the construction progress; reduce the weight of the building, raise the number of layers of the building, reduce the cost.

Advantages of hollow bricks: light weight, high strength, heat preservation, sound insulation and noise reduction performance. Environmental protection, no pollution, is the ideal filler material for frame structure buildings. The brick quality indicators, the test are in line with national standards

Hollow brick, because it is lighter, will not cause cracking of the floor. In fact, there are many other partition wall materials, including light steel keel gypsum board, wire mesh, etc., both light, but also space-saving.

General home improvement when masonry as a brick wall should be used 1/2 brick wall, if you use hollow brick to do, the wall width even within the stucco 120 thick, the main advantage is the light weight is generally 95 brick wall 2/3, will not be too much burden on the structure of the house itself, the sound insulation effect can be because of hollow brick inside the holes in the arrangement of the acoustic function of the consideration of the relatively speaking 95 brick wall thickness and hollow brick wall is the same as that of the wall. Thickness and hollow brick is the same, since the important weight, sound insulation effect than hollow brick to be slightly better.
