From the design mix of concrete, the consistency of freshly mixed concrete depends on several factors, which are as follows: Water Content. Water cement ratio. Fineness Modulus of aggregate. Use of Water reducing admixture (Plasticizers or Superplasticizers) Type and shape of aggregates. Entrained air content.

A cement content of 400 kg/m3 and water-cement ratio of 0.45 will result in paste volume being 30 percent which may be suitable for the former (that is crushed rock of 20 mm maximum size aggregate), whereas cement content of 300 kg/m3 and watercement ratio of 0.50 will result in 25 percent paste volume (Fig. 37) being sufficient to overfill the ...

Mix proportioning for a concrete of M35 grade is given in A·I to A-ll. a) Grade designation : M35. b) Type of cement : OPC 53 Grade conforming IS 12269. c) Maximum nominal size of aggregate : 20mm. d) Minimum cement content : 340 kg/m 3 (IS 456:2000) e) Maximum water-cement ratio : 0.45 (Table 5 of IS 456:2000)

The aggregate size and shape, desired workability, and use of additives are major influencing factors. Table 4 of IS 10262:2019 specifies 186 kg of water for 1 cubic meter of concrete with 20 mm maximum size aggregate. The slump for this value is 50 mm. Estimated water content for 75 mm slump-. = 186 + (3×186)/100 = 191.58 kg.

has been considered as 1.5 per cent for 9.5 mm, 1.0 per cent for 19 mm and 0.8 per cent for 31.5 mm maximum size of aggregate. As a guarantor of quality of concrete in the construction, the contractor should carry out mix proportioning and the Engineer-in-Charge should approve the mix so proportioned. The mix

The mixture proportions used in the present study are selected based on the trial tests conducted as per IS 10262:2009 method of mix design with desirable compressive strength and workability. The control mix was prepared using OPC alone, and for the other mixes, part of cement is replaced with combinations of fly ash, slag, silica …
