Operational Reliability and Durability of Roads with Cement Concrete Coatings

Cement-coated roads are widespread in the world. The leaders in the length of the network of roads with cement concrete coatings are countries such as the USA, Belgium, Germany, Italy and China. Modern technologies for the production of building materials and products based on them must meet at least five fundamental criteria: technological availability and efficiency, resource and energy conservation, environmental safety, natural balance, biocompatible and economic feasibility, ethical acceptability of the use of materials in practice. All these criteria correspond to methods for improving the operational characteristics of cement compositions by activating a mixing fluid with various material and field effects. It is shown that, compared with control non-activated samples, the strength of samples in the cement-water system increases by an average of 33%, of cement-sand samples by 20%, and at the same time of cement-concrete samples by 25%. Thus, the activation of water in the cement-water system will ensure the operational reliability of roads with cement concrete pavement.
