May 17, 2019· For M20, 30 liters of water per 50kg cement . Total amount of water required = 30 x 403.2 / 50 = 241.92 litre. 8.064 bags of cement required for 1 cu.m of M20 grade concrete. 630 kg of Sand required for 1 cu.m of M20 grade concrete. 1260 kg of 20mm Aggregate is required for 1 cu.m of M20 grade concrete.
We know the density of cement in 1 cubic meter = 1440 kg Therefore, the weight of cement = 1.88 x 1440 = 2720 kg. To calculate the required number of cement bags = 2720 kg / 50 (since, the weight of 1 bag cement = 50 kg) = 54.40 bags = 55 bags (approx) So, 555 bags of cement are required for the above RCC slab.
May 17, 2017· Amount of Water Required for 1m 3 of Concrete = 200kgs = 200 litres. Hence 200 Litres of Water is required for 1m 3 of M20 Concrete. Summary: – 8 bags of cement required for 1 cu.m of M20 grade concrete. 672 kg of Sand required for 1 cu.m of M20 grade concrete. 1326 kg of 20mm Aggregate is required for 1 cu.m of M20 grade concrete.
calculate required cement quantity = 1/5.5 × 1.54 × 1440 kg/m3 = 403kg calculate required quantity of water, as 0.55 is w/c ratio for m20 concrete, so quantity of water required for 1m3 of nominal mix of m20 concrete is about 240 litres, maths calculation such as 403 × 0.55 = 220 litres.
