The RMC producer may be the pro in picking the proportions based upon Earlier formulated guidelines and working experience.
After the Roman Empire, the use of burned lime and pozzolana was drastically reduced. Lower kiln temperatures in the burning of lime, insufficient pozzolana, and very poor mixing all contributed to the decline in the quality of concrete and mortar.

High quality began to boost from the 12th century by better grinding and sieving.
In reinforced concrete, the tensile toughness of steel and the compressive strength of concrete function with each other to enable the member to sustain these stresses in excess of substantial spans.
