Correct Ratios for Concrete Mixes

Recommended ratios will enable you to mix concrete to match the function for which it is intended, or the strength of the concrete required. One 50 kg sack of cement has a volume of 33 litres (0,033 cu m). A builders' wheelbarrow, filled level to the top, has a volume of 65 litres (0.065 cu m, which is almost double the volume of a sack).

GFRC Mix and Materials - The Concrete Network

Sand and cement are typically used at a ratio of about 1 to 1, although some mix designs call for slightly higher cementitious materials content (see "GRFC Mix Design," Concrete Décor, June/July 2008). With its high cement content and low water-cement ratio (0.33 to 0.38), GFRC can dry out quickly and not gain full strength.

MIX DESIGN CONCRETE PROCEDURE - AS PER IS CODE | GRADES …

In achieving the required strength of the concrete mix, the water-cement ration ratio plays an important role. The strength of the mix decreases as the W/C ratio increases. The relation between the W/C ratio and the strength of concrete is shown. So, in mixed design, W/C ratio should also be designed to achieve the required compression strength.
