Here we listed the water-cement ratio table as per IS code 10262. : 456-2000 Page-20 Table-5 we get for Reinforced Concrete of M30 Grade the Minimum Cement Content is 320kg per cu.m. Using the next table check to insure the selected water-cement or water-cementitious materials ratio is less than or equal to the maximum permitted ratio. From this curve read off the W/C ratio for a target mean strength of 39 MPa. Water cement ratio Table. The water and air content in concrete and its water-cement ratio can also be estimated using information from the CAC Design Handbook while the gradation of the aggregates can be estimated knowing that: NMAS ≤ 15× Narrowest dimension of form or mold NMAS ≤ 34× Clear space between reinforcement and for some constrictions, Different Water-cement ratios are employed for different concrete applications.

Quantity of water = W/C ratio * Quantity of cement Water/cement ratio as per IS 10262 (2009) for the concrete mix varies from 0.4 to 0.6. 0000108740 00000 n Compressive Water-cementitious materials ratio … In the absence of such data, the preliminary free water­ cement ratio (by mass) corresponding to the target strength at 28 days may be selected from the established relationship, if available. 0 However, water-cement ratio above 0.65 was observed to have a very significant reduction effect on the compressive strength of the lateritic concrete mixes. By using high w/c-ratio cement the amount of hardening material (cement) is lower compared to low w/c-ratio cement. 0.5 W/C ratio. xref Buenfeld At water to cement ratio in excess of 0.45, the hydration process is also overly diluted and creates porous … This agrees with a water/cement ratio for fly ash concrete of 0.72 and a water/cement + fly ash ratio of 0.58. 0000044888 00000 n Limitation chart for w-c ratio shows the maximum value of the w-c ratio as per IS 456: 2000 which can be adopted during mix design. trailer The strength of the concrete, after it cures, will be inversely proportional to the water/cement ratio. As you can see from the Chart, the W/C Ratio varies from 0.4 to 0.7 depending on exposure conditions. blaine finenesses are indicated in parentheses (1 μm = 0.0394 mil) Fig. 0000100963 00000 n Otherwise. 0000002213 00000 n (c) The slump and air content should be with ±0.75 in, … Water-Cement Ratio = Quantity of water/ Quantity of cement. • If a slump cone is available, adjust water to achieve a 2" - 3" (51 - 76 mm) slump Note - Final water content should be approximately 6 - 9 pt (2.8 - 4.3 L) of water per 80 lb (36.3 kg) bag of concrete. 0000046136 00000 n Maximum water/cement ratio 3. For easy placement of concrete, it is a general practice to mix more water, which can badly affect the quality as well as the strength of the concrete. 2.1.2 Standard/Prescribed mixes The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under- or over-rich mixes. used in a concrete mix and can be expressed as. m�yy^�u���S�U�@�cR�껼�A#׊�fJ��{,�Gj|�]I�x �5�~qK����STi�JG�M�B�a�RL�Nj1�W����:ok�W2i-����:�;�Ssb@��~ۀ!
