One of the best concrete mix ratios is 1 part cement, 3 parts sand, and 3 parts aggregate, this will produce approximately a 3000 psi concrete mix. The strength of this mix ratio is good for most concrete slabs, footings, steps, and foundation walls.

Learn MoreMixing the refractory concrete this way, without a concrete mixer machine, is not a very hard job. It's good fun and I find it easier than mixing the pizza dough . A single dome for a wood burning oven takes about 0.5 cubic meter of gravel - it's a small job, and it is interesting/enjoyable work.

Learn MoreA concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency.

Learn MoreThe concrete mix ratio refers to the proportional relationship between the various constituent materials (cement, water, sand, stone) in concrete. There are two ways to express: one is the amount of various materials in 1 cubic meter of concrete, such as 300 kg of cement, 180 kg of water, 690 kg of sand, and 1,260 kg of stone; the other is the ...
