The influence of complex additives
on the endurance strength of concrete

How does a new and complex additive, consisting of polycarboxylate ether as a water-repellent impregnation and a setting accelerator, effect the durability of concrete? The article discusses the influence of this additive on the shrinkage, swelling and sulphate-resistance of the cement mixture, and on the frost resistance, water resistance and porosity.

At present, issues connected with the development of concrete technology, the problem of quality improvement and the durability and profitability of different types of concrete are being addressed through the use of various chemical additives. The admixing of organic and inorganic compounds in concrete enables wide-ranging modification of its physical and mechanical properties, its structure and constituents, and has a posi­tive effect on the durability of concrete and reinforced concrete [1]. Nowadays, special attention is being paid to the development of complex additives that simultaneously...
