Development of high-strength concrete with the addition of a universal superplasticizer

Abstract

Automobile roads perform a particularly important, responsible function in the movement of every automobile, transport equipment. The quality of automobile roads determines the reliability of road construction and automotive equipment, the resource of their work, and, most importantly, ensuring traffic safety. However, the construction of roads and construction methods with the expiration of a certain time undergo significant changes associated with the intensive development of road transport, road construction equipment, an increase in the intensity and flow of traffic. In this regard, there is a need to build high-quality roads and cover roads with durable concrete, which can be achieved by upgrading with composite chemical additives in the composition of concrete - a modernized superplasticizer. The object of this work is a superplasticizer for producing wear-resistant concrete. The introduction of a superplasticizer into the composition of concrete makes it possible to obtain especially strong concrete with an increased service life, which in turn will significantly reduce material costs for raw materials, repair work, and labor resources. The purpose of this study is to obtain a highly effective superplasticizer and particularly durable wear-resistant concrete for road surfaces. To achieve this goal, it is necessary to solve the following tasks: prepare raw materials, develop an optimal component composition and obtain a superplasticizer; in laboratory conditions to obtain a prototype of concrete; determine the quality indicators of the resulting concrete by GOST; to conduct pilot tests for implementation in production.
