Abstract:

The paper presents the compressive strength of mortar samples when replacing natural sand by bottom ash of An Khanh and Cao Ngan thermal power plants (TPPs) in Thai Nguyen province. Experimental research is the main method applied in this research. Research results show that replacing natural sand by bottom ash in the two TPPs, the compressive strength of samples reached the required mortar’s strength. The compressive strength of the mortar sample replaced all-natural sand, particularly for masonry mortar and plastering mortar, is 10.9 MPa and 16.4 MPa respectively for An Khánh TTP, and 12.7 MPa and 12.6 MPa for Cao Ngan TTP, while the compressive strength of the motar used all natural sand, reached 13.2 MPa and 8.6 MPa.
