The energy of concrete is measured in lbs . for each sq. inch or kilograms site for each sq. centimetre of pressure needed to crush a sample of the offered age or hardness. Concrete’s strength is influenced by environmental aspects, Particularly temperature and humidity. If it is allowed to dry prematurely, it could possibly practical experience unequal tensile stresses that in an imperfectly hardened condition cannot be resisted. In the method referred to as curing, the concrete is saved damp for some time immediately after pouring to slow the shrinkage that happens mainly because it hardens.

The hydration course of action is exothermic, which suggests that ambient temperature performs a substantial job in just how long it will take concrete to established. Usually, additives (such as ห้างหุ้นส่วนจำกัดสหคอนกรีตอัดแรง pozzolans or superplasticizers) are A part of the mixture to Enhance the Actual physical Homes with the wet combine, hold off or accelerate the curing time, or usually modify the finished content. Most structural concrete is poured with reinforcing supplies (for instance steel rebar) embedded to provide tensile power, yielding reinforced concrete.
