What is the difference between lightweight cement and cement

The difference between lightweight cement and ordinary cement is obvious, the price is different, the name is different, but each has its own advantages and disadvantages, the following is a brief introduction:

Ordinary cement: mainly cement, and then add the appropriate amount of water, sand, stone cementing and other materials, and then add the chemical additives stirred into. Advantages: that is, low cost, rich materials, long use time.

Disadvantages: is the weight of large, brittle materials.

Lightweight cement: also known as foam concrete, through the chemical according to the need will be introduced into the air such as oxygen and carbon dioxide gas inside the concrete, the formation of different sizes of closed air holes, generally using mechanical methods of foam agent aqueous solution made of foam, added to the water and a variety of admixtures in the material, the formation of a large number of secretion of air holes in the new thermal insulation materials.

Advantages: light weight, heat preservation and insulation function is very good, but also can play the role of sound insulation and fire-resistant, the construction will be very convenient, high compressive strength in 0.5-22.2Mpa, and its price is very affordable.

Disadvantages: slightly lower strength, easy to crack. Lightweight cement, also known as low-density cement, for the preparation of low-density cement paste. This type of cement is suitable for oil or gas wells that encounter rock formations with low pressure, holes, cracks, and high permeability. This cement is manufactured by mixing the right amount of lightweight material into the cement.
