Field notes

The workspace distinguishes between material quantities to weigh and the corresponding amounts in the mix, while accounting for moisture already present in aggregates and admixture. Its example covers a one-cubic-metre M30 batch totaling 2,458.55 kg, with 375.54 kg of cement, 684.65 kg of sand, 1,236.88 kg of stone, 157.73 kg of mixer water, and 3.76 kg of admixture. The site labels these figures as preliminary and directs users toward physical trials and measured fresh density.
