In the early 1990s, the United States firstly put forward the concept of high performance concrete (HPC), from then on, a new era of the concrete water reducing agent was opened. The lignosulfonate water reducer with the pulp as the main raw material was published patent in the early 1950s, and which was gradually marginalized from the concrete market, most of the concrete water reducer manufacturers basically have not sale the lignosulfonate water reducer alone. However, considering the environmental protection and the its cheap price, the lignosulfonate water reducer is regularly used as a component of early strength agent, early strength water reducer, retarding water reducer, pumping aid, waterproofing agent and so on. Additionally, the lignosulfonate water reducer still could prepare high performance water reducing agent compounding with the aminosulfonic acid, melamine, naphthalene formaldehyde and polycarboxylic water reducer. By 2016, the market share of the lignosulfonate water reducing agent is less than 2%.
The naphthalene formaldehyde water reducer was published the first patent as early as 1938, which is still in use today. Then, the melamine water reducer was successfully developed and put into production by Japan kao corporation in 1962. one year later, the first generation of melamine water reducing agent was also successfully developed and put into production in Germany. Along with the development of China's reform and modernization, in the 1970s, the naphthalene formaldehyde water reducer and melamine water reducing agent technology were introduced into China and put into production successfully. By 2016, the market share of the naphthalene formaldehyde water reducer in the field of water reducing agent is about 38% because of its excellent compatibility and good workability.
According <2017 Market Research Report on Global and China Concrete Water Reducer Industry>,the water reducing rate of the aminosulfonic acid water reducer could reach 30%. However, the characteristics of easy bleeding and the high cost limit the development of it. By 2016, the market share of the aminosulfonic acid water reducer is less than 5%. The aminosulfonic acid water was usually compounding with naphthalene formaldehyde water reducer, which could solve the compatibility problem between naphthalene formaldehyde water reducer and cement and reduce the exudation rate of the aminosulfonic acid water reducer.
Due to the wide applicability between the aliphatic water reducer and cement and the obvious enhancement effect, which was widely used as a component of water reducing agent with particular function, such as pumping, retarded, early strength, freeze protection and so on. In the field of water reducing agent market. With the rise of polycarboxylic water reducer, the market share of the aliphatic water reducer is becoming less and less along with the naphthalene formaldehyde water reducer and aminosulfonic acid water reducer. By 2016, the market share of the aliphatic water reducer in water reducer market is less than 7%.
In the 1980s, the first generation of polycarboxylic water reducer was produced in Japan. Then, the international chemical giant Japan kao, BASF and SIKA company had also successfully developed the polycarboxylic water reducer.
With construction activity of all of the countries construction, especially the emergence of high-speed railway, The market share polycarboxylic water reducer increased year by year with its special characteristic of low dosage, high water reducing rate, small shrinkage deformation. By 2016, the market share of polycarboxylic water reducer in the global is about 48% in the whole market of water reducing agent.
Currently, it is difficult to further enhance the water reducing rate of the polycarboxylic water reducer. In order to avoid homogeneity competition, many water reducing agent company launched numerous multi-function polycarboxylic water reducer with the special function such as early strength, shrinkage, crack, antifreeze, retard, waterproof, etc. In essence, it is mainly compound with all sorts of small material in polycarboxylate water-reducer. There have been no breakthroughs with the molecular structure design of the polycarboxylate water-reducer.
As the second largest economy of the world, the water reducing agent Industry of China have achieve a small peak in 2014, After over 30 years of urbanization construction, with the slowdown in the development of domestic economic, the water reducing agent market growth is become slowing. The Middle East and Africa is expected to become one of the fastest growing market because of the post-war construction and urbanization, Europe and North America is a major consumer of multiple high efficiency water reducing agent.
