Concrete is currently the most widely used building material, and my country is the largest user of concrete in the world. As a kind of concrete admixture, water reducer has only a history of several decades, but its development speed is very fast, and it plays a pivotal role in the development of high-strength and high-performance concrete technology.

Since the advent of polycarboxylate superplasticizer in the 1980s, due to its outstanding advantages such as low dosage, good slump retention, and low concrete shrinkage, it has attracted more and more attention from the industry, and has now become a ready-mixed concrete. The main type of water reducing agent is widely used in high-speed railways, highways, bridges, tunnels, subways, high-rise buildings and other national key projects, solving a series of technical problems.

Although concrete water reducer has a very broad market prospect, the complex structure of modern buildings and the harsh construction environment of high temperature and dryness put forward more and higher requirements for the performance of concrete materials, and high-performance concrete water reducer as a New chemical materials are also facing serious environmental problems. These current situations have prompted the research and production units of concrete water reducers to continuously carry out technical innovations on concrete water reducers.

With the current large-scale promotion of housing industrialization, rail transit and other urbanization construction and the international opportunity of the country’s “Belt and Road”, the water reducing agent will help the concrete industry and usher in its own spring. For a long period of time in the future, polycarboxylate superplasticizers will occupy a dominant position in ready-mixed concrete in special structures such as ultra-high-rise buildings and ultra-large spans and in harsh environments such as high temperature.
