Study on Mechanical Properties of Soda Residue / Fly Ash Composite Cementitious Material

Abstract:

The composite cementitious material was prepared with soda residue and fly ash. The mechanical properties were improved by mixing calcined lime and Portland cement, and the mechanism of admixture was researched. The results showed that the 28d flexural strength reached 3.59MPa and the 28d compressive strength reached 9.71MPa., when the proportion of soda residue and fly ash was 40:60 with 9% Portland cement and 7% calcined lime added.
