Polycarboxylic acid series high-performance water reducing agent is a new generation of high-performance water reducing agent appearing at home and abroad in recent years. Compared with naphthalene series and other traditional superplasticizers, polycarboxylic acid series high-performance superplasticizers have many unique technical performance advantages:
With the development of the modern construction industry, concrete technology continues to advance. Among them, HPEG as a new type of high-efficiency water-reducing agent, has attracted widespread attention due to its unique performance and environmental protection characteristics. This article will explore the use of polycarboxylate superplasticizer monomers in the construction industry and the benefits they bring.
1. Polycarboxylate Superplasticizer Powder adjusts the water consumption or sand ratio through experiments according to the concrete design requirements to reach the required water reducer dosage of slump, strength and setting.
HPEG adopts highly active catalyst and special synthesis process, with light appearance, accurate molecular weight, white appearance, narrow molecular weight distribution, low glycol content and high double bond retention.
With the continuous development of the global petrochemical and building materials industries, polycarboxylate monomer TPEG, as an important chemical raw material, is increasingly used in the industry, and market demand continues to grow. Recently, industry analysts have conducted in-depth discussions on the development trends of polycarboxylate monomer TPEG and have predicted future market prospects.
High-efficiency water reducer product overview High-efficiency water reducer is an important concrete additive, which can effectively reduce the water-cement ratio of concrete, thereby improving the strength and durability of concrete. Compared with traditional water reducers, high-efficiency water reducers have the following advantages:
1. TPEG has good adaptability to cement. 2. The cost of TPEG is much lower than that of other types of polycarboxylic acid raw materials. 3. With TPEG solid content of 22% and 1.1% concrete content, the water reduction rate can reach more than 30%.
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.
