Concrete Polycarboxylate Superplasticizer Mother Liquid

Polycarboxylate Superplasticizer (Polycarboxylate Superplasticizer) is a high performance Water Reducing Agent, which is a cement dispersant in the application of cement concrete. Widely used in highways, Bridges, DAMS, tunnels, high-rise buildings and other projects.

The product is green, non-flammable, non-explosive, and can be safely transported by train and car.

In many concrete projects, traditional high efficiency concrete such as naphthalene series can not meet the engineering needs more and more due to the limitation of technical performance. A new generation of water reducing agent that has attracted much attention at home and abroad, polycarboxylic acid series high performance water reducing agent, because it has truly designed an effective molecular structure according to the action mechanism of dispersed cement, has a super-dispersed type, can prevent the loss of concrete slump without causing obvious retarding, and plays a high plasticizing effect under low content. Good fluidity retention, cement to adapt to a wide range of molecular structure, large degrees of freedom, synthesis technology, high performance of a large room for strengthening concrete significantly, can reduce concrete shrinkage, harmful substance content is very low technical performance characteristics, The concrete is endowed with excellent construction workability, good strength development, excellent durability, polycarboxylic acid series of high-performance water reducer has good comprehensive technical performance advantages and environmental protection characteristics, in line with the needs of modern concrete engineering. Therefore, polycarboxylic acid series high performance water reducing agent is gradually becoming the preferred admixture for the preparation of high performance concrete. It is reported that the use of polycarboxylic acid admixtures in Japan has accounted for more than 80% of the total number of high-performance admixtures, and North America and Europe have also accounted for more than 50%. In China, polycarboxylic acid superplasticizers have been successfully applied only in the Three Gorges Dam, Sutong Bridge, Tianwan nuclear power plant, Beijing-Shanghai high-speed railway and other large national water conservancy, bridge, nuclear power, railway projects, and achieved remarkable results.

At the same time, polycarboxylic acid superplasticizer also has some problems: 1. The slump retention under high temperature environment is insufficient; 2. Strong temperature sensitivity, the construction of the same polycarboxylic acid superplasticizer in different seasons, the slump retention of concrete is very different; 3. With fewer functional products, it is difficult to meet the requirements of ultra-high and ultra-long distance concrete pumping, negative temperature construction, preparation of ultra-early strength concrete and high durability of concrete; 4. High viscosity, in the preparation of high blend material and low water-binder ratio concrete, the concrete viscosity is high, which is not conducive to construction; 5. Strong sensitivity to the mud content of sand and stone aggregate. [2] The adaptability to machine-made sand is also poor, and the sensitive content affects the construction.

Good compatibility with all kinds of cement, good slump retention performance of concrete, extend the construction time of concrete.

2, low content, high water reduction rate, shrinkage.

3, greatly improve the early and late strength of concrete.

4, this product has low chloride ion content and low alkali content, which is conducive to the durability of concrete.

5, the production process of this product is pollution-free, does not contain formaldehyde, in line with ISO14000 environmental protection management international standards, is a green environmental protection products.

6, the use of polycarboxylate water reducer, more slag or fly ash can be used to replace cement, thereby reducing costs.

Except PCE, concrete formula also need other additives such as Defoamer, Air-Entraining Agent, fibers, retarder and so on.
