Concrete is one of the most versatile and easy-to-use building materials available anywhere in the world. The guidelines in this page can help builders and DIY enthusiasts make their own concrete and make their building projects a huge success.
When building projects, you might want to calculate the right quantity of concrete you have to prepare in order to avoid wastage of reources.
The calculation for the volume of concrete required to fill a square of rectangular section is: Width X Length X Width.
For a circular section, to calculate the volume of concrete required, use the formula: (Diameter^2) X 0.8 X Height
Structural concrete sections for any project are designed for specific thicknesses. For unreinforced concrete elements, the typical thickness are given in the table below.
Before pouring concrete into foundations, make sure that the trenches are damp but with no standing water. This will place the concrete in a self-curing environment with three sides prevented from drying out by the soil. The sub-base for foundations, surface beds and ground slabs should be well compacted.
Ensure that the formwork is clean and adequately supported to retain the mass of the concrete.
Make sure that the steel reinforcing is adequately secured to ensure that it does not move while placing the concrete.
