Assessment of the influence of water-cement ratio on the strength of concrete with activated cement
Incoming article date: 25.03.2017Cement 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.
