Make a unilateral concrete to reduce water consumption by 20% -30%. Compared with ordinary water reducer, superplasticizer even larger amount, the slump reached 20cm-30cm, Lianyungang polycarboxylate liquor, it will not cause excessive bleeding and segregation phenomenon occurs and delay setting time. Polycarboxylate superplasticizer is a kind of molecular structure was comb, containing more carboxyl polymer surfactants at low dosage, without changing at the same time concrete workability of concrete can be significantly reduced water consumption, and significantly improve the strength of concrete; or significantly alter the workability of the concrete in a low water-cement ratio and slump when small loss. Its low dosage, high water reduction, high slump performance, low shrinkage of concrete, and cement better compatibility, adjustable and strong molecular structure of high performance potential and environmental advantages make it increasingly The more widespread concern civil sector researchers. Development of high performance concrete and specialty mortars makes polycarboxylate superplasticizer admixtures will become the future trend of development and applications. Recognized as the world's excellent performance superplasticizer, polycarboxylate superplasticizer exhibited a series of very good performance. Early 1960s, appears on the foreign market three superplasticizer (or superplasticizer), which are naphthalene sulfonate formaldehyde condensates, polycyclic aromatic sulfonate formaldehyde condensates and melamine sulfonic acid formaldehyde condensates. Early 1960s, Yancheng polycarboxylate liquor, Japan and Germany began using superplasticizer in concrete. China in the early 1970s started to develop superplasticizer, and the corresponding varieties can produce, gather acid liquor, 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. Yangzhou liquor polycarboxylate, polycarboxylic acid liquor, high strength provided by the Linyi City Building Materials Co., high-strength construction materials. 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!
