DetailsSo total numbers of cement bags 0154 0035 44 bags So the weight of the cement 44 x 50 220 kg Also Read Some useful tips to work out the quantity of cement sand aggregate in concrete SAND 310 x 154 0462 m 3 The density of sand 1450 kgm 3 approx So the weight of the sand volume x density 0462 x 1450
in my country one bag of cement is 50kg or 0035cum and for measuring aggregates and sand we use head pans00175cum for 1cum of concrete the expected materials are cement 65bags sand 044cum26headpans aggregate0 08851headpahsbut on site we have to use more material to achieve the expected volume instead of the estimated calculations
STEP 4 Calculate the commercial volume for sand and cement Once we got the total volume we need to split into commercial sizes what will define the total quantity of bags of sand and cement needs to be purchase A 20kg standard density bag of general cement has around 0347 m³ So 0265 m³ 00347 766 bags Approx 8 Bags
Volume of dry Concrete 154 to 157 times Volume of wet concrete Also Read Some useful tips to work out the quantity of cement sand aggregate in concrete Here 157 is taken as factor of safety Therefore total concrete volume required is 157 m 3 Calculation of Volume of Cement in 1m 3 of Concrete
Specific gravities of concrete materials are as follows Cement 315 Sand 26 Coarse aggregates 26 The percentage of entrained air assumed is 2 The mix proportion of 1153 by dry volume of materials can be expressed in terms of masses as Cement 1 x 1500 1500 Sand 15 x 1700 2550 Coarse aggregate 3 x 1650 4950
M20 1 cement 15 sand 3 stonebrick aggregate To determine the proportions you have to perform mix design for this you have to find out the of cement CA FA and water cement ratio
Use the largest aggregate practicable Use the optimum ratio of fines to coarse aggregate A low water to cement ratio is the number one issue that affects concrete quality Do not add too much water Components in concrete Portland Cement the aggregate and sand is coated by a paste formed from the cement and water This paste then hardens
Calculate concrete volume and cost of concrete slabs footers walls columns steps curbs and gutters in cubic feet cubic yards and cubic meters Calculate for quantity of items to fill for a total project need of cement in cubic feet and cubic yards Yardage of concrete
