Hydration and hardening of concrete over the first 3 times is vital. Abnormally rapid drying and shrinkage because of components for instance evaporation from wind in the course of placement could bring about improved tensile stresses at a time when it hasn't nonetheless obtained enough strength, leading to bigger shrinkage cracking. The early strength with the concrete can be increased if it is held moist over the curing method.
Lime is applied considering that Roman periods possibly as mass foundation concretes or as light-weight concretes employing a number of aggregates coupled with a wide array of pozzolans (fired materials) that enable to realize elevated energy and speed of set.
