Abstract. The effect of very fine aggregate on the water requirement and strength evolution of superplasticized concrete was studied. The maximum aggregate size was 6 mm, fine aggregate content 0–15% of the total aggregate, binder (OPC and silica) content 80–800 kg m −3, and specific surface area of the finest aggregate material 18–1000 m 2 kg −1.

### Effect of aggregate properties on the strength and ...

The strength of lightweight aggregate directly affects the compressive strength of concrete because the aggregate compressive strength is much lower than the strength of cement paste. When the volume fraction of lightweight aggregate is 18%, concrete elastic modulus and the compressive strength are controlled by the cement paste.
