The hydration procedure is exothermic, meaning that ambient temperature performs a major role in just how long it takes concrete to set. Often, additives (for example pozzolans or superplasticizers) are A part of the combination to improve the Bodily Attributes from the soaked mix, delay or accelerate the curing time, or usually modify the finished content. Most structural concrete is poured with reinforcing แผ่นพื้นสำเร็จรูป products (like steel rebar) embedded to offer tensile power, yielding bolstered concrete.
