The third and fairly important component of concrete is water. Thanks to the flowing chemical processes, thanks to which the gravity and subsequent hardening is obtained, cannot be realized without water. You need to know that all the surfaces of the concrete structure during hardening and finish set, be sure to keep in a wet state. If this process is not performed, then the mixture of cement will simply burn out, as a result of which it will only have a part of the desired margin of strength. For the correct hardening of the concrete mixture, only pure water is needed. If this water is from the crane, and you are confident in its purity, then you can do without all sorts of studies. It happens, then there is no near the central water supply, then it will be necessary to carry out additional studies for a detailed determination of the presence of substances harmful to the composition of concrete. At first glance, water can be quite suitable, but with a detailed analysis, it may reveal that it contains an increased content of salts, as a result of which the life of which will be significantly reduced.
Today, for individual construction, various additives began to be used, which accelerate and increase the processes of hardening and frost resistance, they also make the process of grasping faster. The most active component is calcium chloride, the people know it as an accelerator of hardening, as well as an anti -gun silicate supplement based on gypsum. But at the same time, the majority do not even imagine what irreparable consequences can be if you overdo it with these additives. Always know the measure, and your buildings will be strong and eternal.
