Keyword: «lean concrete»

The accumulated experience in the operation of road surfaces in the climatic conditions of the Republic of Sakha (Yakutia) shows that one of the options for increasing the period between repairs of roads is the use of a hard surface – asphalt concrete pavement on a cement concrete base. To reduce shrinkage and temperature deformations inherent in cement concretes, it is advisable to use «lean» concretes, i.e., concretes with a low binder content. The use of mechanical activation technologies in the production of «lean» concrete is an effective way to control the performance properties of building materials.
