I mixed some cement mortar, cement and sand ratio is about 1:7. what is the usual 1:1, 1:3?

Home renovation construction, cement and sand mixed with the correct ratio:

Usually, the renovation of pasting tiles, floor tiles, small repair with cement mortar cement and sand ratio should be

1:2.5 or 1:3

And never 3:1

This ratio is the weight ratio. In the past, because of the site of civil construction site mixing concrete or cement mortar, usually in the warehouse and mixer truck hopper next to a special structure "weighing" --- carts can be weighed by pushing on the weight.

But the general renovation of small-scale construction, in order to control the amount of ash, often converted to volume ratio.

For example, when laying bricks when the ground area is determined, the area multiplied by the average thickness, both the amount of cement mortar to get the bulk volume, so that the mortar mixing is good, neither waste to meet the requirements of the process, but also because of the shortage of mortar delayed paving time.

Other uses of cement mortar, mixed mortar ratio is as follows:

One: wall grouting ------ refers to the imitation of brick walls, cultural stone, etc.

1: cement: sand 1: 1

2: the original mortar scraping and grouting

Second: indoor general wall plastering

1: brick wall plastering: 1: 3 lime plaster mortar

2: concrete, concrete masonry wall block plaster 1: 3: 9 cement plaster mortar

3: aerated concrete slat wall block plaster 1: 3: 6 cement plaster mortar ......

Currently, the large mold template concrete wall is rarely plastered, the grass-roots interface treatment, directly scraping putty.

Three: wet room and corner protection:

Cement is a water-hardened material (you can see that the bridge pier is not afraid of blisters), and mixed mortar, lime is air-hardened material, so if the bathroom kitchen and other wall plastering, shall be used cement mortar.

Mixed mortar has a disadvantage that the hardness is not as good as cement mortar, so in the plastered wall corners, door openings, etc., in the distance from the ground below the position of 1800, the need to use cement mortar to do the corner (hold the corner). Currently. Home renovation usually do more doors, hole sets, so, own plastered walls, can also be omitted.

The proportion of cement mortar, mixed mortar is not unique, according to different walls, different needs proportion.

Family home improvement paste face tiles, floor tiles, small repairs with cement mortar cement and sand ratio should be

1:2.5 or 1:3, of which, when paving the floor tiles, generally should be 1:3 dry hard mortar.

Home improvement cement is generally used 42.5 silicate cement, in addition to clear water wall hooking, the use of general medium sand, medium coarse sand can be.

Traditional door and window opening gaps with cement to fill, and now the general finished doors and windows and other fixed gaps to fill more expansion sealant. The picture below is an example of filling the interior bathroom door frame with expansion sealant.

The first layer for the bedding layer, gravel, pebbles can be (hourglass), sand, cement ratio of 3:1:1;

The second layer for the transition layer (leveling layer), the ratio of sand and cement 4:1;

The third layer for the surface layer, the ratio of sand and cement 2.5:1.

Above is the volume ratio.

For reference.

Wall tiles and floor tiles cement and sand ratio are similar, in general, the proportion of cement and sand is 1:3, the use of 32.5 cement, the cement grade can not be too high, at the same time, the mixing ratio of cement and sand, the proportion of cement can not be too large, the grade is too high and the mixing ratio is large, may cause tiles drumming, peeling or cracking!

Paving tiles generally use 32.5 ordinary cement. Sand ratio of 1:2.5,

Cement adhesive wall tiles, paste should be added to the appropriate amount of 108 glue to enhance adhesion. (30% glue + 70% water), adjust as you go, (cement mortar ratio of 1:2

Cement sand ratio is generally 1 to 3, but the teams of tilers may be different. A good cement is one that does not need to be gummed, and our team never uses gummed cement. Gummed cement is good to work with, but has hidden quality problems later.

Contact with a lot of friends to reflect the case of cracked tiles, some of which is due to the improper mixing ratio of cement sand caused by the cement or cement grade is too high due to the proportion of cement, the adhesion of tiles is strong, the brick can be very quickly stained, but the proportion of cement mixing is high, the coefficient of expansion of the cement mortar is large, it is easy to squeeze the tiles cracked after the paving.

The recommended ratio, wall tiles for 1:3, floor tiles for: 1:2, cement cement standard for 32.5 cement.

It depends on the floor or wall tiles, floor tiles dry paving method is 1:3, while the wall tiles using wet paving method 1:2, in addition to the degree of wall tiles soak with the drums have a relationship.

This is my homework collected for your reference

Label 425 cement paving tiles, then, with the proportion of sand for how much? How many square meters of floor tiles can be paved with one generation of cement?

Generally use 1:2 dry mortar to pave, you can use your hand to grab a handful of fall from a meter high to disperse as well; generally about the normal range of gray mouth can be paved 2-3 square.
