· Typically, a mix is about 10–15 wt% cement, 60–75 wt% aggregate, and 15–20 wt% water. Entrained air in many concrete mixes may also take up another 5–8 wt%. The character of the concrete is determined by the quality of the paste. The strength of the paste, in turn, depends on the ratio of water to cement.

· Therefore, there is not a good correlation between compressive strength and calculated porosity. Conclusions (1) The presence of stone dust in sand causes opposing effects on the strength of mortars. The first effect is negative, as it increases the water demand; while the second, the filler effect, is positive.
