Water Cement Ratio means the ratio between the weight of water to the weight of cement used in concrete mix. Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 . M25) We all know that water cement ratio will directly affect the strength of concrete.

cement content resulting in 28-day compressive strength being the highest (see Fig. 24’3. Increasing the cement content above the optimum value may not increase the strength of concrete specially for mixes with low water-cement ratio and larger maximum size aggregate’. Recommendations for making durable concrete in various codes of

A-6 CALCULATION OF CEMENT CONTENT Adopted w/c Ratio = 0.44 Cement Content = 158/0.44 = 359 kg/m 3 From Table 5 of IS 456, Minimum cement content for ‘Moderate’ exposure conditions 320kg/m 3 = 359 kg/m 3 > 340 kg/m 3 hence ok. A-7 PROPORTIO0N OF VOLUME OF COARSE AGGREGATE AND FINE AGGREGATE CONTENT

Table 5 Minimum Cement Content, Maximum Water-Cement Ratio for Mix design of M25 grade concrete – IS456 codebook II. TEST DATA FOR MATERIALS . Values in this section should be based on the laboratory tests as per codebook. Here standard values of different materials are assumed for the mix design of M25 grade concrete.

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.

Apr 08, 2014 Calculating Cementious Material Content. From the water cement ratio and the quantity of water per unit volume of cement, calculate the amount of cementious material. After calculating the quantity of cementious material, compare it with the values given in the table shown in Step-4. The greater of the two values is then adopted.

A-6 CALCULATION OF CEMENT CONTENT Adopted w/c Ratio = 0.41 Cement Content = 158/0.41 = 385 kg/m 3 From Table 5 of IS 456, Minimum cement content for ‘Very severe’ exposure conditions 340kg/m 3 = 385 kg/m 3 > 340 kg/m 3 hence ok.

May 17, 2017 To calculate the individual quantities of cement, sand and aggregate required for 1m 3 assume a nominal mix grade of concrete such as M20. You can use same method to calculate any grade of concrete. Concrete Mix Design for M20 Grade Concrete:-Now let us consider M20 grade concrete; As per IS456:2000, M20 Grade concrete proportion is = 1 : 1.5 : 3

Aug 03, 2018 CALCULATION FOR AGGREGATE QUANTITY. Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3. Aggregate = (3/5.5) x 1.54 = 0.84 m3 ∴ 3 is a part of cement, 5.5 is sum of ratio. Density of Aggregate is 1500/m3. Calculation for KG = 0.84 x 1500 = 1260 kg. As we know that 1 m3 = 35.31 CFT.

Concrete 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

6. Calculation of cement content-- Once the water content and the w/c ratio is determined, the amount of cement per unit volume of the concrete is found by dividing the estimated water content by the w/c ratio. weight of water weight of cement wc Mix Design Procedures However, a minimum cement content is required to

7 CALCULATION OF CEMENT CONTENT. As discuss earlier adopted based on trial w/c Ratio = 0.44. Cement Content = 154/0.44 = 350 kg/m³,from Table 5 of IS 456, minimum cement content for ‘moderate’ exposure conditions is 300 kg/m³ but taken 350 kg/m³ > 300 kg/m³ hence ok.

14 free water content and cement content, hence the free w/c ratio. The same method can also be used to calculate 15 the degree of hydration. The proposed method has the advantage that it is quantitative and does not require 16 comparison with calibration graphs or reference samples made with the same materials and cured to the same

• As per I.S.: 456-2000 Page-20 Table-5 we get for Reinforced Concrete of M30 Grade the Minimum Cement Content is 320kg per cu.m. of concrete, and Maximum cement content for any grade of concrete is 450kg per cu.m. of concrete. Hence our calculated value of cement content satisfies both the minimum and maximum cement content criteria hence okay.
