Helpful advice from Belle in how to get your concrete mix right first time

Mixing



Mix Ratios

The correct mix ratio (cement: sand: stone) depends on the type of application; harder concrete requires more cement, rougher applications require more aggregate. The ratios given below are guidelines: best proportions may depend on the quality of sand/stone used.

First put in the water - around 7 litres (1 gallons), using more or less depending on the type of mix required. Add some aggregate before adding cement, to avoid sticking. Work consistently to the ratio of ingredients for whatever type of concrete mix you are working to.
Application Qualities
Cement Sand Stone
Most ordinary 1 2 4
Foundations 1 3 6
Rough Mass Concrete 1 4 8
Waterright floors, tanks, pits, etc 1 1.5 3
