Polylactic acid-based additive application beginning in the name of "higher than Naphthalene family" label, from the publicity also too much emphasis on the advantages and weaken even mention its shortcomings, so that the user will be its expect too much, polycarboxylate liquor content in the practical application discovery advertisement moisture. I think there are advantages and disadvantages of each material, poly-carboxylic acid liquor prices, the performance of the two aspects exist simultaneously. Adaptability Polycarboxylate admixtures and cementitious materials and aggregate adaptability and compared with other series of additives, no obvious advantage. First, polycarboxylate liquor manufacturers, and adaptability cementitious materials, with different varieties and different brands of cement adaptability is vastly different, adaptability is not very good, often in cohesion terms of concrete mixture, water aspect is even worse. Of admixtures, such as fly ash quality requirements is still relatively high, conforming Ⅱ Ⅲ grade level or quality of fly ash, some indicators relatively high, the performance of concrete mixture significantly deteriorated, including liquidity, slump, air content, slump losses. According to the survey, China superplasticizer product manufacturers are only a few independent research and development, production enterprises from most other universities or research institutes Institute of the introduction of technology, poly-carboxylic acid liquor, or the introduction of technology from other companies launched produced. Due to limited manufacturer's own technology, for the production of superplasticizer technology deep enough understanding, difficult to adapt to raw materials, a variety of changes in technology, product quality and stability does not arise. It is therefore recommended superplasticizer producers actively with universities and research institutes jointly, to fully understand the various factors superplasticizer product performance, adjust synthesis parameters, in order to stabilize the quality of products, and through joint or independent research and development, strengthen technical reserves to meet market demand in addition, superplasticizer raw material standards as soon as possible and the stability of superplasticizer raw materials prices, to ensure superplasticizer stability of product performance is also very important.
