Influences of Limestone Aggregates on Concrete Strength in Pipe Piles Production

Article Preview

Abstract:

Taking the limestone and siliceous rocks as coarse aggregates to mix concrete,through normal pressure steam curing and autoclave curing,the concrete compressive strength after demould and compressive strength after autoclave curing are tested.The results indicate that the concrete compressive strength increases obviously after normal pressure steam curing when taking the limestone and granite as coarse aggregates,and the strength increasing laws are basically in accordance.However,the concrete compressive strength is great different after autoclave curing when taking the limestone and granite as coarse aggregates,the concrete strength increases lower with limestone as coarse aggregate,but the concrete strength increases higher with siliceous rocks as coarse aggregate.
