Concrete technology/Aggregate properties A 1000g sample of coarse aggregate in the SSD condition in air weighed 633g when immersed in water, Calculate the BSG of the aggregate. If some sample from same batch of aggregate after being exposed to air dry condition for some time weighed 978 g in air and weighed 630 g after they immersed in water for 2 hours, calculate the moisture content, MC(SSD), of the air dried aggregate at that time
