Abstract

  This project aims to study the compressive strength, density and water absorption properties of cement non-shrink grout containing cement mortar at the age of 7, 14, and 28 days. The cement mortar is a mixture of cement to the sand ratio of 1:1 and

1:1.5 and use the water - cement ratio at 0.3 and 0.4 instead of cement non-shrink grout at 0%, 10%, 20%, 30%, 40%, and 50% by volume The results showed that the use of cement mortar at 1:1 and 1:1.5 instead of cement non-shrink grout at 10% by volume, the compressive strength increase while density and water absorption comparable to that of cement non-shrink grout without cement mortar in mixture. In addition, the cement mortar has a lower cost of materials than the cement non-shrink grout.

   From the experimental results, it can be concluded that the cement mortar be replaced cement non - shrink grout with optimum content.
