The effect of surfactants and water-cement ratio on abrasion resistance of hydraulic concrete are presented. A series of laboratory tests and field surveys of hydraulic structures were carried out to determine the effect of various factors on wear resistance of hydraulic concrete to abrasive effects. Studies were carried out by comparison of laboratory tests for abrasion of mortar and concrete. Sulfite-alcohol bard (SAB) was used as a hydrophilic surface-active additive and as a hydrophobic soap. Structural changes of properties were studied by electron microscopic analysis. The presence of dependencies of the abrasion of concrete on several factors was established: water-cement ratio and strength, the type of filler, the fineness of cement grinding, the age of the samples, the use of surfactant additives, and the method of laying.
