Aug 15, 2018· As an Engineer, Quantity Surveyor and Site Manager on Construction Site, you must know how to calculate this in other to prevent wastage of Material and for full accountability of Total Tons of Granite used for a Particular Volume of Concrete The calculations below is all about 1:2:4 mix ratio of Concrete TOTAL RATIO = 1+2+4 = 7Answer (1 of 2): you divide each component by its specific gravity to calculate its volume the specific gravity of cement is approximately 315, water is 1 and aggregate varies but typically is 264 1 cubic metre = 1000 litres volume of 400kg of cement = 400 /How to calculate the volume or amount of sand, cementConcrete Calculator Keohane Readymix concrete is supplied in cubic metres, from a minimum of 1 cubic metre upwards in 05 cubic metre quantities Once you have your measurements use our Concrete Calculator below to work out how much you need Select the basic shape of your space – rectangle, circle or triangle, then insert yourConcrete Calculator Keohane Readymix

Select the volume type you want to calculate from the five options below Enter the length (m), width (m) and depth (mm) of the slabs Enter the overall lengths (m) of the footings, and their width (mm) and depth (mm) Enter the height (m), diameter (mm) and number of columns Enter the step width (m), riser height (mm), step depth (mm) andAug 03, 2018· Consider volume of concrete = 1m3 Dry Volume of Concrete = 1 x 154 = 154 m3 (For Dry Volume Multiply By 154) Now we start calculation to find Cement, Sand and Aggregate quality in 1 cubic meter concrete CALCULATION FOR CEMENT QUANTITY; Cement= (1/55) x 154 = 028 m 3 ∴ 1 is a part of cement, 55 is sum of ratioHow To Calculate Cement, Sand & Aggregates Quantity inThus, the quantity of cement required for 1 cubic meter of concrete = 098/01345 = 729 bags of cement The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 729 x 50 = 3645 kg Weight of fine aggregate (sand) = 15 x 3645 = 54675 kgCalculate Quantities of Materials for Concrete Cement

Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix Ans Materials required are 7 nos of 50 kg bag of cement, 042 m 3 of sand and 083 m 3 of stone aggregateThis concrete calculator will help you in estimating the amount of concrete needed for your project The amount given as needed, does not include any waste It is recommended, depending on the job you are doing, to add anywhere from an extra 4% to 10% to your concrete order to make sure you have enough concrete to finish the jobSlab Concrete Calculator Metric
