Crushed rock sand – An economical and ecological ...

2016-9-1  Considerable reduction in compressive strength was noticeable at and beyond 50% CRS replacement. Therefore for mix with 70−100% CRS replacement it is desired to mix washed crushed rock sand along with proper screening at crushing stages so that one gets compressive strength higher than the designed strength. c.

Study of the internal re-breaking characteristics of ...

The strain-stress of broken limestone can be divided into three stages: initial compression, linear compression and plastic compression. The initial compression stage occurs at 5–10% of the compressive strength. When axial stress reaches 5–30%, the stress–strain curve exhibits obvious linear features.

Comparison of properties of steel slag and crushed ...

2003-3-1  The compressive strength of steel slag aggregate concrete, with 50 and 55% aggregates was marginally, about 2 MPa, less than that of crushed limestone aggregate concrete. Therefore, a coarse aggregate to total aggregate proportion of 50% may be adopted to minimize the weight effect of heavy steel slag aggregates.

Therefore, the strength variations of crushed limestone sand concrete after exposal to high temperature can be similarly treated as that of the natural sand concrete. Also it can be seen that the CLSC can use 0.5 power law equation to represent the relationship between compressive and splitting tensile strength before and after exposal to high ...
