Observations Concrete is a mixture of cement, sand (fine aggregate), aggregate, water, and and OPC cement (ordinary portland cement). Proportions of each ingredient are adjusted to obtain a well balanced-mix in oder to be sent to be built. Concrete will roughly set between the 9 and the 10 hours and continues to harden. A 250,000lbf (1,112kN) capacity machine can test 6x12in cylinders up to 7,000psi (48.3mPa), but if 4x8in cylinders are used, strengths can range up to 15,900psi (109.6mPa). If 4x8in cylinders are permitted, we recommend a lighter 250,000 testing machine. A 300,000lbf capacity machine will test 6x12in concrete cylinders up to 8,500psi (58.6mPa).
