WATER REQUIREMENT FOR DIFFERENT CONCRETE GRADES AS PER IS456 CODE. For design mix concrete water content is calculated from Wate/Cement ratio which depends on various factors like the weight of cement, workability etc. But for nominal mix concrete IS456 codebook suggests the following quantities per bag of cement. CONCRETE GRADE: WATER PER 50KG BAG OF CEMENT

MoreFrom above method, we can calculate the quantity of sand, cement and water in mortar. Water Cement ratio of different grade of Concrete Table. Normally, we used the water-cement ratio falls under 0.4 to 0.6 per IS Code 10262(2009) for nominal mix i.e. M7.5, M10,M15,M20,M25.

More03/08/2018· Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio Density of Cement is 1440/m 3 = 0.28 x 1440 = 403.2 kg We know each bag of cement is 50 kg For Numbers of Bags = 403.2/50 = 8 Bags

MoreConcrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. 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. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

MoreConcrete strength at a time t (3.1.2) Expressions are given for the estimation of strengths at times other than 28 days for various types of cement f cm(t) = β cc(t) f cm where f cm(t) is the mean compressive strength at an age of t days β cc(t) = exp {s[1-(28/t)1/2]} The coeeficient s depends on type of cement: s = 0,20 for rapid hardening

MoreA similar adjustment can be carried out for limestone; the limestone content can be estimated by determining the CO 2 content of the cement and calculating the coresponding CaO. If either slag or fly ash is present, in principle the formula could be adjusted to take it into account, but the slag or ash composition would need to be known accurately and in practice this is not an adjustment

MoreThe formula for calculation of materials for required volume of concrete is given by: Now we will calculate the volume of concrete that can be produced with one bag of cement (i.e. 50 kg cement) for the mass proportions of concrete materials. Thus, the absolute volume of concrete for 50 kg of cement = Thus, for the proportion of mix considered, with one bag of cement of 50 kg, 0.1345 m 3

MoreStep 4 — Selection of Cement Content. Water-cement ratio = 0.5. Corrected water content = 191.6 kg /m 3. Cement content = From Table 5 of IS 456, Minimum cement Content for mild exposure condition = 300 kg/m 3. 383.2 kg/m 3 > 300 kg/m 3, hence, OK. This value is to be checked for durability requirement from IS: 456.

More26/01/2017· Formula, Cement = (Volume of dry concrete/a+b+c) Calculation For Water Content: Let us assume the water/cement ratio of the concrete is 0.45. w/c = 0.45. Required water for 1 bag cement = 0.45 × 0.0353 = 0.0159 cum. Where volume of 50 kg cement = 0.0353 cum. 1 m3 water = 1000 Litre. Required water for 1 bag cement=0.0159 × 1000 = 15.9 Litre. ∴ Required water for 6.33 bags cement

More17/06/2016· The water-cement ratio to be used must be as per the contract. Step-1-Batching of cement. Cement is always measured by weight. Mostly it is used in terms of bags. One bag of cement weighs 50 kg and has a volume of 35 litres (or, 0.035m 3). Cement should not be batched by volume because its weight per unit volume varies according to the way the container is filled. Step-2-Batching
