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.

2. Water: Water is essential for the chemical reaction that hardens the cement and gives concrete its strength. However, using too much water can weaken the mix, while too little can make it difficult to work with. . 3. Sand: Sand provides bulk to the concrete mix and contributes to its workability.

Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 1:7, 1:8 or 1:9. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a one-storey building. The blocks may be solid, cellular or hollow.

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard.
