Remove the specimen from the water after specified curing time and wipe out excess water from the surface. Take the dimension of the specimen to the nearest 0.2m. Clean the bearing surface of the testing machine.
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more ...
The Cube Test Controller enables the fully automatic control of a hydraulic press for the testing of concrete cubes. Cube Press is designed to conduct compression and crushing strength tests (ACV) on Concrete cubes.

efore the concrete is scooped into the moulds the moulds must be lightly coated in a mould release agent. This ensures that the concrete does not stick to the mould and makes it easier to remove the cube. When using a 150mm mould, the concrete sample is scooped into the mould in 3 equal layers (50mm) and compacted between each layer.
Their answer will be following: The compressive strength of M20 concrete is approximately 13.5 MPa (1958 psi) at 7 days. To calculate the compressive strength of M20 concrete used the formula:- F = P/A, compressive load = 304 kN, cross sectional area A = 150mm ×150mm = 22,500 mm^2, then compressive strength = 304 /22,500 = 13.5 …
