What's a 124 Mix? Concrete Construction Magazine

I have a residential-concrete specification that calls for a 124 concrete mix. What does that mean? This is a little-used method for showing the amount of cement, sand, and coarse aggregate in the concrete. The specification should also say if those proportions are by weight or volume. If the proportions are based on weight, use 4 pounds of

CIP 28 Concrete Slab Moisture

Committee 302 is to place the concrete directly on a vapor retarder for interior slabs on grade (CIP 29).Use a concrete mixture with a moderately low water-cementitious material (w/cm) ratio (about 0.50). This reduces the amount of residual moisture in the slab, will require a shorter drying period, and result in a

Corrosion of Steel in Concrete — What, Why, & How

Quality ConcreteConcrete Practices. The first defense against corrosion of steel in concrete is quality concrete and sufficient concrete cover over the reinforcing bars. Quality concrete has a water-tocementitious material ratio (w/c) that is low enough to slow down the penetration of chloride salts and the development of carbonation.

What Are the Mix Ratios for Cement and Sand?Reference

The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud. Lime is also a common additive to the mix. Concrete and mortar can be made from a mixture of

Concrete can be ordered in ½ yard increments. SlumpSlump is a measure of the consistency of the concrete. A 4 inch slump (the measure of the distance a wet concrete cone will fall) is typical. If you want more slump, it is always safest for the concrete to adjust slump at the plant. Adjusting slump at the job site will damage the concrete.
