About this site

Cement mortar is an intact combination of cement and sand mixed with ample amounts of water to create synthetic paste. Its adhesive characteristics vary, depending on the amount of water added the mixture. It has four basic types. "Lean" mortar has a minimal amount of cement content while the "rich" type contains a high volume of cement.
