The development and improvement of the road network is a strategic task of the Islamic Republic of Afghanistan. To develop the sparsely populated territories of the country, it is necessary to build and repair thousands of kilometers of highways, a significant part of which is located in the piedmont and mountainous areas. Considering the fact that the Republic of Afghanistan is characterized by a dry and hot climate, as well as a variety of soil and hydrological conditions, one of the main road building materials for solving this problem is road cement concrete, which has recently become the subject of intensive research. This article presents the results of researching the effect of the Adinol Rapid 2H additive (which is a hardening accelerator additive) on the technological properties of the concrete mixture and the strength of cement concrete.
