In many traditional concrete engineering concrete polycarboxylate efficient liquor content, naphthalene-based, because of the limitations of technical performance, increasingly unable to meet the engineering needs. Concern at home and abroad of a new generation superplasticizer, polycarboxylate superplasticizer, due to the truly cement dispersion mechanism based on the design of effective molecular structure, with ultra-dispersed poly acid synthesis mother liquor can be prevented concrete slump loss without causing significant slow agglomeration acid liquor, played at low dosage high plasticizing effect, to maintain good liquidity, cement adapt to a wide degree of freedom of the molecule structure, synthesis and more, High Performance there is considerable room for concrete reinforcing effect is significant, can reduce concrete shrinkage, low content of harmful substances and other technical performance characteristics, gives concrete excellent workability, good strength development, excellent durability, Polycarboxylate superplasticizer has a good overall technical performance advantages and environmental protection, in line with the needs of modern concrete project. Thus, polycarboxylate superplasticizer is becoming the preferred preparation of high performance concrete admixtures. It is reported that Japan polycarboxylate admixture amount accounted for more than 80% of all high-performance equipment liquor polycarboxylate admixture products of the total, North America and Europe account for more than 50%. In China, superplasticizer has been successfully applied only in the Three Gorges Dam, Bridge, Tianwan Nuclear Power Plant, the Beijing-Shanghai high-speed rail and other large state water, bridges, nuclear power, railway projects and achieved remarkable results. [4] polycarboxylate superplasticizer concrete performance indicators Water Reduction /% bleeding rate of not less than 14 ratio /%, not more than 90 gas content /%≤3.0 coagulation time difference / min initial setting of -90 - + 120 final setting compressive strength /% shrinkage ratio of not less than 1d1403d1307d12528d120 /% and not more than 135 polylactic acid liquor content, Jincheng polycarboxylate liquor, high-strength high-strength building materials provided by the Building Materials Co., Linyi.
