Early 1960s, Hebei ready-mixed mortar admixtures, appears on the foreign market three superplasticizer (or superplasticizer), ready-mixed mortar admixture buy, they are naphthalene sulfonic acid formaldehyde condensates, more PAHs sulfonate formaldehyde condensates and melamine sulfonate formaldehyde condensate. The early 1960s, Japan and Germany began using superplasticizer in concrete. China in the early 1970s started to develop superplasticizer, and the corresponding varieties can produce 2005 annual output of about 1.11 million tons, the output is still growing every year. In recent years, with the structural design requirements continue to increase the rapid development and concrete admixture technology, and now the construction of concrete slump, strength, impermeability, bending, antifreeze and other aspects of the increasingly high demand, Common superplasticizer has been difficult to meet the construction requirements. Development superplasticizer inevitable. The current domestic configuration of high-strength concrete superplasticizer are used, can be divided into four categories: Naphthalene (Naphthalin), multi-carboxylic (Polycarboxylic acid), three melamine-based (Melamine), amino acid-based (Aminosulfonic acid ). The above four categories superplasticizer, based on these four components of the main categories. In Japan are collectively referred to as high-performance AE water reducing agent. After incorporating concrete water reducer, superplasticizer hydrophobic groups adsorbed on the cement particle surface orientation, while the hydrophilic groups point to an aqueous solution to form a single molecule or molecular layer adsorption film. Since directional adsorption of surfactant, cement particles surface with a charge of the same sign, ready-mixed mortar admixture wholesale, so the role of sex repulsion, not only to make cement - water system in a relatively stable state of suspension, Also, make flocculent structure of cement in Canada early dissolution of the water formed dispersion, thereby flocculation released within the structure, to achieve the purpose of water reduction. After the reducing agent is added, not only can make fresh concrete to improve the workability, and because the concrete water-cement ratio have decreased greatly, so that the internal pore volume was significantly reduced cement, cement denser concrete resisting significantly improved compressive strength. Reducing agent to join, but also to cement hydration rate, setting time has an impact. In practice these properties are very important.
