With the development of concrete technology, the requirements for polycarboxylate superplasticizers are more refined, not limited to the basic performance advantages such as water reduction rate and moisture retention. Since the polymerization of polycarboxylate superplasticizer is designable, polycarboxylate water reducing agent with special functions can be prepared according to specific engineering requirements, such as slow release type, early strength type, anti-shrinkage type and low bleed type. , low viscosity type, etc. The main steric hindrance group of the polycarboxylate superplasticizer is the longer polyoxyethylene side chain. The nature of the water-soluble nonionic polyoxyethylene soft segment allows its conformation in aqueous solution to vary. The conformational state of the side chain has a great influence on the water reducing agent.
For all kinds of concrete admixtures, the role of the precipitant is mainly to reduce water consumption, increase the density and elasticity of the concrete, and make the concrete durable. The air entraining agent can improve the solubility of the concrete, and reduce the internal crack of the concrete by improving the internal structure of the concrete, so that the concrete can improve its antifreeze and impermeability. For concrete with higher frost resistance requirements, it is possible to properly perform bleed air or a mixture of precipitation additives. For concrete with higher impermeability requirements, the density of concrete must be increased by high-performance precipitants. At the same time, the air entraining additive is used to reduce the occurrence of water seepage and improve the impermeability of the building structure.
Cement is a very basic material in the construction industry and plays a very important role in the development of the national economy. However, in the cement production process, the energy consumption is high and the utilization rate is low, mainly due to the accumulation of fine powder particles during the grinding process, which causes the paste ball and the adhesive liner to reduce the grinding efficiency, so that about 80% to 90 % of the energy is consumed in the form of heat. In order to improve this situation, it is common in the industry to add a small amount of grinding aid to the grinding material to improve the grinding effect.
Rate and reduce the energy consumption of grinding.
Our company will have the Chinese New Year holiday from February 1st to February 13th, 2019.
Since the logistics company will stop transport operation in around January 25th, our company decides to only accept orders during this period and does not arrange shippment till the end of the Chinese Spring Festival.
Hereby inform the customer

Triisopropanolamine (TIPA) is a surface active material that can greatly reduce the surface tension of water. When the cement is stirred with an aqueous solution doped with a trace amount of triisopropanolamine (TIPA), the surface tension of the solution is changed. The effect of the solution on the emulsification, wetting, permeation, adsorption and dispersion of the cement particles is remarkably enhanced, and it is easier to expand and adsorb on the surface and inside of the cement particles, so that the deep layer of the cement continues to be hydrated. Triisopropanolamine (TIPA) has a strong polarity due to its spatial three-dimensional molecular structure. It can play a good role in dispersing particles during cement grinding, so that cement particles do not agglomerate and form a larger ratio. Surface area, thus achieving a grinding effect.
