Currently, the major foreign markets superplasticizer accounts for about 50% of naphthalene superplasticizer and other water reducer 25% each; the domestic market accounted for 75% of naphthalene superplasticizer, polycarboxylate-based Save agent close to 15%, 10% other additives. Advantages of naphthalene superplasticizer flooring is better adaptability, Guangdong-acid liquor, but because of its high content of formaldehyde, poly acid liquor, large-scale production process pollution, its application is gradually restricted. Especially for medium-sized cities, the future trend will inevitably lead to increased cost of production of naphthalene water reducer, superplasticizer gather from abroad is much higher than the market share of naphthalene water reducing agent will be able to see it . But as the project quality requirements and extend the life of Taiwan polycarboxylate liquor, naphthalene superplasticizer can not guarantee the durability of concrete. If the Fe-Al tetra-calcium content is high, it is relatively slow rate of hydration is also adsorbed more water reducer, and tricalcium aluminate hydration resulting crystals consumes more water, leading to its fluidity is reduced. Form gypsum cement impact on retention fluidity Polycarboxylate great, Yunnan poly-carboxylic acid liquor, if hemihydrate gypsum content and its gypsum reacts with water to consume more water, so that the net paste fluidity loss quickly. In addition to cement, concrete raw fly ash, slag, stone and clay have a significant impact on superplasticizer application performance. Adding fly ash and slag of better help to improve the initial mortar flow and liquidity retention.
