The role of concrete superplasticizer Without changing the ratio of various raw materials, adding concrete superplasticizer will not change the strength of concrete, and can greatly improve the rheology and plasticity of concrete, making concrete construction Construction can be carried out by means of self-flow, pumping, and unnecessary vibration, which can increase the construction speed …
Dongke Polycarboxylate superplasticizer is produced by our monomer. Our own factory located in Fushun, it’s near the Fushun refinery- which is also the source of raw material EO. So when talking about the concrete superplasticizer, there’s 1 important index is the water reducing rate. The water reduction rate is the ratio of the difference between …
Superplasticizer is essentially a kind of building materials, in use will produce foam and bubble and other sol bubbles, and they have different characteristics and formation mechanism, is caused by ionic superplasticizer. After adding the superplasticizer to the concrete, the superplasticizer will be adsorbed on the surface of cement particles. Generally, about 80% of the superplasticizer …
In fact, as early as 1938, the technology using naphthalene sulfonate as the main component was patented in the United States, which is regarded as the predecessor of high-efficiency water-reducing agent; Because the design strength of concrete at that time was sufficient, it was possible to adjust the water consumption to achieve the required workability …
High-efficiency water-reducing agent is also called plasticizer or dispersant. Its appearance is divided into water agent and powder. It is a kind of water-reducing agent that can reduce the necessary unit water consumption in concrete and improve its workability under the requirements of the specified consistency of concrete Admixture. It is mainly divided into three …
The Japanese catalyst company Tsubaki Hengxiong invented the polycarboxylic acid water-reducing agent in the 1980s. Its molecular structure is no longer the same as the linear structure of the previous high-efficiency water-reducing agent. Comb-shaped molecular structure composed of chains and long polyoxyethylene side chains. Immediately afterwards, an ester-based carboxylate water-reducing agent obtained by copolymerization of …
Concrete additives for concrete are like salt for a dish. A dish is inseparable from salt, and concrete is inseparable from concrete additives.Its amount is very small compared to the total amount of concrete, but it is indeed essential. In many concrete projects, traditional high-efficiency concrete such as naphthalene is less and less able to …
Superplasticizers (SP’s), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with ca. 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and …
The additives in concrete areas following: Early strength agent, water reducing agent, retarder, quick setting agent, antifreeze, anti-seepage agent. The proportion of admixture in concrete is generally: 0.5 ~ 1%,Related extensions: Concrete admixtures are referred to as admixtures for short, which refers to substances added to improve the performance of concrete during the mixing of …
Polycarboxylic acid superplasticizer is a third-generation high-performance superplasticizer developed after ordinary superplasticizer represented by wood calcium and superplasticizer represented by naphthalene series. It is the most advanced and scientific and technological content in the world. A high-efficiency water-reducing agent with the highest, the best application prospect and the best comprehensive performance. The liquid is light …
