Depending on the poly-carboxylic acid based superplasticizer products into its main chain structure of two categories: one acrylic or methacrylic acid-based chain, graft different side chain length of the polyether. The other is based maleic anhydride grafting different side chain length of the polyether. On this basis Polycarboxylate, it spawned a series of different characteristics of superplasticizer products. [2] before the polycarboxylate admixture occurs, there are lignin sulfonates admixtures, naphthalene sulfonate formaldehyde condensates, melamine formaldehyde condensate, acetone sulfonate formaldehyde condensate, an amino sulfonate formaldehyde condensate and the like. The early 1980s, Japan developed the first successful superplasticizer. A new generation of polycarboxylate type superplasticizer overcome some shortcomings of traditional Polycarboxylate superplasticizer applications, with low dosage, slump good performance, low shrinkage concrete, adjustable and strong molecular structure, high Performance of the potential, the production process does not use formaldehyde and other outstanding advantages. [3] Polycarboxylate while there are some problems: a slump lack high-temperature environment; 2 temperature sensitivity is strong, the same kind of Polycarboxylate in different seasons construction, concrete slump of the difference. far; 3. Functional products less Polycarboxylate production, it is difficult to meet the high, ultra-long distance concrete pumping, negative temperature construction, preparation of ultra strength concrete and concrete high durability requirements; 4. Polycarboxylate small high viscosity material, blending material in high and low water-cement ratio concrete preparation, the concrete viscosity is high, is not conducive to construction; 5 for sand and gravel aggregate clay content strong sensitivity. Polycarboxylate application, Haimen polycarboxylate water reducer, high-strength high-strength building materials provided by the Building Materials Co., Linyi. Linyi high-strength building materials Limited (www.lygqjc.cn) strong, credible, concrete and Shandong Linyi products and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead high-strength construction materials into the brilliant and you work for a better future!
