The dry volume of concrete mixture is always greater than the wet volume. The ratio of dry volume to the wet volume of concre;te is 1.54. So 1.54 Cum of dry materials (cement, sand and aggregate) is required to produce 1 Cum of concrete. Volume of Cement required = 1/(1+2+4) X 1.54 = 1/7 X 1…

Feb 09, 2018· Let me tell you one thing, before I am gonna answer your question blindly. Quantity of sand depends upon which grade of concrete your using. Sand = (dry volume of concrete x it's Ratio) / (sum of ratio's) Where, Dry volume = wet volume x 1.54 Ther...

Concrete is created using several ingredients. Coarse aggregate or "ballast" is a primary component. This is added to cement that binds the aggregate particles together. Water and any additional additives are also used to create the final mixture ready for pouring. The properties of concrete can vary widely depending on the amount of ingredients used […]

Calculate the amount of concrete needed and the cost of concrete per cubic metre(s) To use this calculator you need to know the square metres of the area you need to pour concrete in. It can be length x width of a slab, height x length of a footing or wall, anything you can calculate square metres from.
