MPa is the metric unit for pressure or stress called megapascal (MPa). The term is used in concrete as the common unit for compressive strength. If you have a project which requires a defined strength of concrete - i.e. 20MPa to set the posts for a raised deck - then its time to call Mini-Crete Concrete and have concrete delivered it’s the only way to guarantee the structural strength in the concrete.
It takes approx 15 wheel barrows to unload 1 cubic metre of concrete
To mix 1 cubic metre of concrete by hand you need 1.5 tonnes of gravel 0.75 tonnes of sand and 10 bags of 20kg cement then add clean water.
The weight of 1 cubic metre of concrete is approx 2400kg.
To work out the volume of concrete always remember length x width x depth.
It takes approx 110x20kg premixed concrete bags to make 1 cubic meter
