Mechanical Properties of Concrete with Compound Mineral Admixtures

Abstract:

The influence of multi-component composite mineral admixtures on the mechanical properties and workability of concrete is studied in this paper, such as steel slag (SS), blast furnace slag (BFS) and fly ash (FA). Considering the above-mentioned factors, the optimal mixture ratio and substituted amount of composite mineral admixtures replacing equally cement are obtained. The results showed that composite mineral admixtures reduced the early compressive strength of concrete with composite admixtures, but significantly improved the workability and later compressive strength of concrete with composite admixtures. On the other hand, the optimal mixture ratio and substituted amount of double-mixing mineral admixtures are different.
