geopolymer ncrete with crusher sand

Manufactured sand is a substitute of river sand for concrete construction. Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to a construction material. The size of manufactured sand is less than 4.5mm. The specific gravity of this m-sand is 2.66. 1.3 ...

Concrete Mixing Ratios - How To Make Concrete

Generally, when the stone ratio is more than the sand, this concrete cures a little stronger than a 1:3:3 ratio. The difference is in the workability of the concrete. The sand tends to make the concrete a little more easier to work with. The less sand the rockier the mix is going to be. Cool things you can make by mixing your own concrete

Calculate Quantities of Materials for Concrete

2021-5-6  The percentage of entrained air assumed is 2%. The mix proportion of 1:1.5:3 by dry volume of materials can be expressed in terms of masses as: Cement = 1 x 1500 = 1500 Sand = 1.5 x 1700 = 2550 Coarse aggregate = 3 x 1650 = 4950. Therefore, the ratio of masses of these materials w.r.t. cement will as follows =
