Concrete Mix Design | Different Grades of Concrete

To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-.

Optimised mix design and elastic modulus prediction of

Method of mix design. The UHSC mix design proposed by Sobuz et al. was used as a referred mix. The original proportion of this concrete mix was 1:1.1:0.266 ratio by weight of cement, aggregate and silica fume. However, there are several changes in raw materials for cost-reduction in manufacturing.

How Much Water Is for 60-pound Concrete Mix? | Hunker

Add Water. It is best to start with the minimum amount of water listed on the 60-pound bag of concrete's label. For hand-mixed concrete, add the water in all at once. If you use a concrete mixer, add half before you start the machine and the other half while the concrete is mixing. Mix the water in well.
