To date, almost none modern construction site can do without the use of cement. Ease of use and financial accessibility make this material indispensable for most construction works. Therefore, it is very important that the cement stone obtained during construction meets the necessary requirements when erecting construction projects. The theoretical aspect of the issue of dependence of the water-cement ratio on strength is considered in the article. A number of experiments were performed, taking into account the experience of other researchers with the aim of determining the reliability of data, obtained earlier. The results obtained during the experiment confirmed that the increase in water-cement leads to a decrease in the strength of the cement stone.

Cement is the main building material, which is an inorganic artificial binder. The popularity of cement is due to its properties, which are unique to it, namely: cement is gaining strength even in wet conditions. The most common cement is concrete cement. From the water-cement ratio of concrete mix depends first of all the strength of hardened concrete. The theoretical aspect of the issue of dependence of the water-cement ratio on strength is considered in the article. A number of experiments were performed, taking into account the experience of other researchers with the aim of determining the reliability of data, obtained earlier. The results obtained during the experiment confirmed that the increase in water-cement leads to a decrease in the strength of the cement stone.
