Abstract
With the increasing demand of concrete performance in modern construction engineering, the research and application of new high-performance concrete admixtures has become an important direction of concrete technology development. This paper focuses on the research and development and application of new high performance concrete admixtures, aiming at discussing their technical principles, types, performance advantages and specific application effects in engineering practice. The basic concepts and technical principles of new high performance concrete admixtures are summarized in this paper. New high performance concrete admixtures refer to specific chemicals added in the concrete preparation process, through their unique chemical and physical effects, significantly improve the performance of concrete, such as strength, durability, permeability resistance, crack resistance and so on. These admixtures are usually composed of a variety of functional components, through catalysis, complexation, dispersion and other mechanisms to achieve the optimization of concrete microstructure and macro performance improvement. The types and performance advantages of new high performance concrete admixtures are introduced in detail in this paper. According to the different functions, the new high performance concrete admixtures can be divided into water reducing agent, strengthening agent, water preventing agent, anti-cracking agent and other types. Water reducing agent can significantly reduce the water-cement ratio of concrete and improve the fluidity and strength of concrete. The reinforcing agent can improve the strength and durability of concrete by improving the crystal structure and chemical composition of concrete. Waterproofing agent can effectively prevent water penetration and improve the impermeability and durability of concrete. By optimizing the internal structure of concrete, anti-crack agent can reduce the crack and improve the crack resistance and toughness of concrete. These admixtures have significant advantages in improving the performance of concrete and can meet the high requirements of concrete performance in modern construction projects. This paper discusses the concrete application effect of new high performance concrete admixtures in engineering practice. Through the actual case analysis and experimental data verification, the new high performance concrete admixture has been widely used in high-rise buildings, large Bridges, tunnels and other projects, and has achieved remarkable results. These admixtures not only improve the strength and durability of concrete, but also reduce the difficulty and cost of construction, and provide a strong guarantee for the quality and safety of engineering.
