Ex. 1:1.5:3 is the ration of M20 and now how much sand or cement or aggregate we use in this? 4.4 bag of cement is required for 1cum of concrete work in M10. volume of . instead if we assume or have: Total volume ingredients for using as 2.36 (varies), [this is when you know the overall amount of materials you have].
Answer / shah sohail. M10 IS 1:3:6. Cemnet=1. Sand=3. Agg=6. Wet Dry Cocrete Is 1.52. Total Ratio =1+3+6=10. Cement=1/10*1.52=0.152. Sand=3/10*1.52=0.456. Agg=6/10*1.52=0.912. Cement Is 0.152*1440kg/cum=218kg=4.3Bags Approx Cement Is 4 Bags. Sand =0.456cum*35.32cuft/cum= 16cuft. Agg=0.912cum

and determining their relative quantities with the objective of mixes of fixed cementaggregate ratio which ensures adequate strength are termed The proportions generally adopted are as given below. 7. C502.5. Grade of. Concrete. Nominal Mix proportions. (Cement: FA : CA). M 5. 1:5:10. M7.5. 1:4:8. M10. 1:3:6. M15.
Aug 31, 2012 On the occasion of Concrete Day, Nagesh Puttaswamy looks into the basic mixture so vital in construction. Cement requires a specific amount of water to complete the chemical reaction any excess water will not participate in the chemical reaction but It is designated as M10, M20, M25 and so on.
Feb 7, 2017 A simple yet more accurate method (DLBD method) of calculating cement, sand and aggregate for Nominal Concrete mix M15, M20, M25 and M30 grade showing Grade of concrete, material ratio, materia requirement ( cement, fine sand, 20mm metal, 15 mm metal, water consumption) for M10,M15,M20,
Adding more water (Water Cement Ratio) on concrete to increase the concrete workability ??? Absolutely Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 . M25) If we need to calculate Water quantity for concrete, first find the cement content for the volume.
The compressive strength of hardened concrete which is generally considered to be an index of its other properties. therefore. thus the aim is to produce as lean a mix as possible. quality and quantity of cement. water and aggregates. it cannot be properly placed and compacted. Requirements of concrete mix design The
Jul 27, 2016 this is very good question and the most important part in site supervision there are different ratio s used in various cases in which we would opt for water cement ratio 4 to 6 according.
Concrete is classified into different grades like M5, M7.5, M10, M15 etc., where M stands for Mix and the following number stands for characteristic compressive strength(fck) of concrete in 28 IS456 Code book recommends the following quantities of total aggregate per 50kg of cement to produce nominal mix concrete.
grade M10 = 1 : 3 : 6. ratio sum = 1+3+6 =10. let volume of concrete = 1 cubic meter(wet volume). therefore dry volume of concrete= 45% to 55% increase in volume x wet volume. dry volume = 1 x 1.54(assuming 54% increase in volume). dry volume = 1.54. cement quantity in 1.54 cubic meter concrete. in cubic meter =( part
Feb 7, 2017 A simple yet more accurate method (DLBD method) of calculating cement, sand and aggregate for Nominal Concrete mix M15, M20, M25 and M30 grade showing Grade of concrete, material ratio, materia requirement ( cement, fine sand, 20mm metal, 15 mm metal, water consumption) for M10,M15,M20,

Jul 11, 2015 IS 4562000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. For the concrete with undemanding performance nominal or standard mixes (prescribed in the codes by quantities of dry ingredients per cubic meter and by slump) may be used only for
