  • Seven Misunderstandings of Polycarboxylic Acid Superplasticizer

    Polycarboxylic acid water reducing agent is a commonly used cement and concrete water reducing agent, which has the effect of reducing water and slumping. The rational use of polycarboxylic acid water reducer is more effective.1. The water reduction rate fluctuates, which is not easy to control in t

  • Causes of cracking in concrete

    Concrete is an important material used in engineering construction, and has many advantages such as low price and energy saving. But concrete is not a material with perfect technical performance, and the problem of shrinkage cracks is a problem that has not been solved for a long time. There are man

  • Polycarboxylic acid water reducing agent matters needing attention

    The precautions of polycarboxylic acid water reducing agent mainly include the following six points:1. There is a problem with the adaptability of cement. For some cements, the water reduction rate is low and the slump is large. Therefore, when the cement adaptability is not good, the concrete trial

  • Why we choose Polycarboxylate ethers as Construction Chemical

    In the early 19th century, dispersive admixtures were used. However, in the 1960s, sulphonated melamine formaldehydes and analogous naphthalene derivatives were introduced. Nowadays, new admixtures based on polycarboxylate ethers are being developed. Polycarboxylate ethers possess structural characteristics that provide more fluid concrete, which is more resistant to segregation and exudation as compared to that prepared with the previously known superplasticizers. Polycarboxylate ethers have been commonly utilized to enhance the flow ability of cementitious materials. Moreover, polycarboxylate ether is one of the most effective types of plasticizers, water reducer, and disperser which promotes excellent flow ability, high strength, workability, and pump ability, and efficient dispersion for gypsum, cement, and ceramic materials.

  • Definition of concrete segregation and performance of concrete segregation.

    Concrete segregation refers to that the amount of the pumping agent exceeds the saturation point of the cementing material, and the resistance between the particles of the cementing material decreases and the displacement accelerates.
