To get to the sand content you have to minus a 1000L from the volume of each of the materials in the mix and multiply the volume of the sand by the RD of the sand eg. Water 240 kg / 1 (rd of water) = 240L water. Cement 624kg / 2.80 (rd of cement )= 223L of cement. Stone 1050 / 2.72 ( rd of stone) = 386L in volume.
