Concrete Technology: Compression testing Machine Procedure and also the Different Concrete Strength values for different Concrete Ratio"s

Question

Accepted Answer

Compression testing machine is used to determine the strength of concrete. Different concrete ratios have different strength values.

Compression testing machine is used to apply a compressive force to a concrete sample until it fails.
The procedure involves preparing the concrete sample, placing it in the machine, and gradually increasing the load until failure occurs.
The maximum load applied to the sample is recorded as the compressive strength of the concrete.
Concrete strength values vary depending on the ratio of cement, aggregates, and water used in the mix.
Higher ratios of cement to aggregates result in stronger concrete.
Common concrete strength values include 20 MPa, 25 MPa, 30 MPa, 35 MPa, and 40 MPa.
For example, a concrete mix with a ratio of 1:2:4 (cement: sand: aggregates) may have a compressive strength of 25 MPa.
