• Investigate potential causes such as improper curing, incorrect mix proportions, or poor quality materials.

• Take corrective measures based on the investigation findings, such as adjusting mix proportions, improving curing methods, or replacing materials.

• Consult with structural engineers to assess the i...read more

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.
