Effect of water consumption on performance of polycarboxylic acid water reducer The influence of water consumption of polycarboxylic acid water reducer is very obvious. In the practical application of concrete engineering, sometimes if the water consumption increases by 1~3kg/m3, the concrete will show serious bleeding, resulting in pitting, sanding, holes and other defects on the concrete surface. The uniformity of concrete pouring and construction quality cannot be guaranteed, resulting in the reduction of the strength and durability of the concrete structure.

In modern construction projects, concrete is a widely used building material, and its performance directly affects the quality and durability of the project. With the advancement of science and technology, the research and development of concrete additives has become a key way to improve the performance of concrete. Among them, HPEG Polycarboxylate superplasticizer monomer has become a major innovative breakthrough in the field of concrete technology in recent years with its excellent water-reducing performance and the characteristics of improving concrete workability.

Polycarboxylate superplasticizer is a new generation friendly environmental superplasticizer. It is a concentrated product, best high water reduction, high slump retention ability, low alkali content for the product, and it having high strength gained rate.It can be widely used in premix of common concrete, gushing concrete, high strength and durability concrete. Especially! It can be used in high strength and durability concrete having excellent capability .

Under the condition that the slump of concrete is basically the same, the admixture of mixing water can be reduced. According to the size of its water-reducing rate, it can be divided into ordinary water-reducing agent, high-efficiency water-reducing agent and high-performance water-reducing agent.

The common description of the performance of Polycarboxylic Superplasticizer is: high water reduction rate, very good adaptability to cement, good workability of concrete, no loss of slump in one hour, etc. In fact, the composition of cementitious materials is complex and changeable. From the perspective of adsorption dispersion mechanism, any admixture can not adapt to all situations.

From June 19th to 20th, the 37th International Fine and Specialty Chemicals Exhibition was held at the Düsseldorf Exhibition Center in Germany, attracting representatives from the global chemical and materials industries. As a company focusing on chemicals and materials, East Chemicals showcased its unique solutions at the exhibition with high-performance chemicals and advanced materials as its main line.

CPhI North America 2024 will be held in Philadelphia, USA from May 07-09. As the world's top professional exhibition for the pharmaceutical industry, CPHI North America is the only pharmaceutical industry event in the United States that covers the entire industry chain including drug research and development, production, and packaging.

On April 29, the three-day 16th Chongqing International Battery Technology Forum/Exhibition (CIBF2024) concluded successfully at the Chongqing International Expo Center. During this period, East Chemical shined at the venue with its hard-core products, providing one-stop solutions for chemical raw material manufacturers.

How much can the water reduction rate of polycarboxylic acid high-performance water reducer reach? First of all, we should know that the water reduction rate of polycarboxylic acid water reducer refers to the percentage of water consumption that can be reduced under the specified dosage, that is, the water reduction rate. For example, it was originally necessary to use 100g of water to make the mortar mix.

VAE Re-dispersible Polymer Powder is the powder formed after the polymer lotion is dried by spray, also known as dry powder glue. This kind of powder can be rapidly reduced to lotion after contacting with water, and maintain the same properties as the initial lotion, that is, the film will be formed after water evaporation. This film has high flexibility, high weather resistance and high adhesion to various substrates.
