sets

When mixed with water, cement sets to a hard mass. It first forms a plastic mass which hardens after some time due to 3-dimensional cross-links between the --Si-O-Si-- and --Si-O-Al-- chains. The first setting occurs within 24 hours whereas the subsequent hardening requires a fo..

Two sets A and B are said to be equal if and only if they contain the same elements i.e. if every element of A is in B and every element of B is in A. We denote the equality by A = ..

Cement absorbs water on mixing to form a gelatinous mass. This sets to a hard mass and is very resistant to pressure. This process is called the setting of cement. This simple looking process involves a complicated set of reactions of hydration and hydrolysis, leading..
