Then click on the Compute button. Please note that densities will vary somewhat between different loads, but the default values assigned for the various aggregates are good standard "rules of thumb" for estimating. In addition, it calculates the total weight if you know the density of the crushed material. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume This is a Volumetric Calculation. Unit in kg/m 3 or lb/ft 3. Aggregate calculator formula. Carefully enter values for the length, width & depth in all the red fields. Choose a density of 1.76 for concreting ballast, 1.50 for pea shingle and use 2.00 for scalpings. Width: Depth: You will need approximately: Tonnes. Key Features: If the volume is unit then, Bulk Density= Mass. The calculator first works out the area and volume of the space using the measurements you provide. Cubic Meters Cubic Yards. In this definition, the volume is that contain both the aggregates and the voids between aggregates particles. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. The Tonnage Calculator helps you to estimate the amount of aggregate required for your job.

Use the top form for Metric and the lower form if you prefer feet & inches. For Cement, Sand and Coarse Aggregate.
