Dimensional stability portlandcement of mining sand Kildyamskoe deposits

Stringing cement - is expanding, straining cement with very low shrinkage. For unshrinkable concrete is small or non-existent as a plastic shrinkage and shrinkage after curing. Cements have not so useful in the construction of a property, contractual shrinkage, making it difficult to repair and installation work. This problem is solved by using non-shrink Portland. Since the non-shrink cement binder consists of cement and plaster - this may give ettringite formation, and as a result - uncontrollable increment of the linear volume. To control this process, we decided to use as a stabilizer in an active mineral additives mountain sand
