The rate of loading is 0.6 ± 0.2 N/mm2/s. Record the maximum force from the machine. The same procedure is followed in the testing of concrete cylinders also. Compressive strength can be calculated from the following equation. Compressive Strength = Applied Maximum Load / Top surface area of the specimen.

You need to apply 40 tonnes of load for 20mm aggregates in period of 10 minutes by uniform loading, at the end of 10 minutes, total load will reach to 40 tonnes. Check your CTM loading unit, in most of the cases it is Kn/sec. do calculation to arrive at rate of loading required to apply load for 10 minutes with uniform loading.

With variation in rate of loading on concrete specimen, the strength varies proportionately. At higher rate of loading, the compressive strength increases. The increment is from 30% to almost 50% of the original strength. However, at lower rate of loading, the reduction in strength of concrete cube compared to its true strength is insignificant.
