Effect of water absorption by the aggregate on
aggregate. The strength-density ratio was affected by the moisture condition of the aggregate. Thus, dry lightweight aggregate gave 9 MPa higher compressive strength at a density of 2000 kg/m3 compared to that of prewetted aggregate. The water absorption by the lightweight also affected the microstructure of the hardened concrete.
