Concrete admixtures, referred to as admixtures for short, refer to substances added before or during concrete mixing to improve the properties of fresh concrete and/or hardened concrete. The characteristics of concrete admixtures are many varieties and
small dosage, which play an important role in concrete modification. With the gradual development of the construction industry, the demand for concrete in engineering projects continues to increase, and at the same time, there are higher requirements for the performance and quality of concrete. In this context, as an important engineering material that can greatly enhance the performance of concrete, concrete admixtures have become an indispensable fifth component in modern concrete besides cement, sand, stone and water.
High-performance water-reducing agent Water-reducing agent is mainly divided into three categories: ordinary water-reducing agent, high-efficiency water-reducing agent and high-performance water-reducing agent. The development of superplasticizers has gone through three stages: the first generation of ordinary superplasticizers represented by wood calcium, the second generation of superplasticizers represented by naphthalene series, and the third generation of superplasticizers represented by polycarboxylate superplasticizer series. Generation of high-performance superplasticizer stage. Polycarboxylate superplasticizer has the advantages of low dosage and high water reduction, and can be used to formulate high-strength, ultra-high-strength, high-durability and super-fluid concrete; The process has no waste liquid, waste gas, waste residue discharge and other factors. It is a green and environmentally friendly high-performance water reducing agent, and has obvious advantages in environmental protection and efficiency. With the expansion of production capacity and the improvement of permeability, polycarboxylate superplasticizers have become the main varieties of superplasticizers currently produced and consumed in my country.
In the context of the "steady growth" expected to continue to heat up, the increase in the demand for concrete brought about by the increase in the planning of major engineering projects and the advance of the construction schedule will increase the demand for concrete admixtures at the same time. In addition, according to the government work reports issued by various provinces, infrastructure construction such as transportation and water conservancy projects account for a large proportion of major projects, and the above-mentioned projects have higher performance requirements for concrete, and high-performance water reducers are required to meet the requirements of concrete. Compared with other types of admixtures, the pumping construction needs and the vibration reduction and even vibration-free needs of special concrete projects have obvious advantages. Therefore, the proportion of the demand for high-performance water-reducing agents that can achieve "tailor-made" engineering projects will be expected to increase further.
Jufu Chemical Company's functional material business other than the main business of superplasticizers reflects the underlying product logic that is very different from its competitors. In the future, it will be able to replicate the success of the superplasticizer business, and the market space ceiling is much higher than that of superplasticizers.
