Preparing the right mix for solid concrete | Farmstyle

Slump — The slump test is used to classify the workability of the concrete, which governs how easy the mix is to work and handle. It is measured by filling a hollow cone mould — which is 300 millimetres high and has a 100mm diameter at the top and 200mm at the bottom — with concrete, compacting it and then removing the cone.

High Strength Concrete Mix Ratio. The high strength concrete mixing ratio is M50 to M70 grade and is designed by hand. For M70, the amount of cement, sand, and coarse aggregate are batched by volume according to the design mix. Mixing ratios used for concrete of varying strength. Concrete mixing ratios are accurate.
