While you may be presented with some challenges when pouring concrete in colder temperatures, many often find that the extra effort and additional procedures taken pay off in the end. In the winter & colder temperatures, concrete must be continuously protected from freezing and freeze-thaw cycles in its early stages. Extra steps must be taken to ensure that the concrete doesn’t get cold too quickly, which would result in the concrete weakening, increasing the risk for cracking and breaking. By taking certain precautions, you can pour concrete in the winter.
What is Ready-Mix Concrete?
In its basic form Ready Mix Concrete is the mixture of sand, stone, cement and water. The cement (a dry fine powder) is combined with water to form a paste which is than mixed with fine and coarse aggregates (sand and stone respectively) to form a solid material when cured. The sand acts as a filler between the larger pieces of stone in ready mix concrete. There can be other cementitious ingredients added to concrete such as fly ash, ground granulated blast furnace slag and silica fume, in addition to a range of admixtures that can be used to enhance and change the properties of ready mix concrete.
