The hydration system is exothermic, meaning that ambient temperature plays an important part in how much time it takes concrete to set. Generally, additives (like pozzolans or superplasticizers) are A part of the combination to Increase the physical Houses from the moist blend, hold off or accelerate the curing time, or normally modify the concluded material. Most structural concrete is poured with reinforcing components (which include steel rebar) embedded here to supply tensile toughness, yielding bolstered concrete.
