In the country the past few years, in order to meet the development requirements of high-performance concrete and concrete construction technology, needs to have a large water reduction, good workability, adaptability good superplasticizer cementitious materials, and polycarboxylate just to meet this demand, and therefore should be widely applied. Aiming Polycarboxylate nature and concrete performance carried out tests of concrete, pointing out the presence of Polycarboxylate deficiencies. 1) According to local market conditions, choose a target cement C-1 test. 2) Target cement C-1 and poly-carboxylic superplasticizer slump experimental study carried out in Anhui mixed mortar admixture plant, Polycarboxylate content is 0.25% of ready-mixed mortar admixture plant, measuring cement pulp 0 min, 30 min, 60 min mixing polycarboxylate superplasticizer and not adding cement paste fluidity. Specific experimental procedure: ①, the glass plate is placed in a horizontal position Hefei mixed mortar additive plant, a glass plate with a damp cloth to wipe evenly blender and stir the pot, so that it does not wet the surface with water droplets; ②, the truncated cone round mold on the glass center, stand covered with a damp cloth; ③, cement weighed 500g, was stirred into the pot; ④, water was added 145g (admixtures of liquid, shall be deducted from its water content), stirred 4min; ⑤ , marinated paste rapid injection molding frustum round mixed mortar admixture plant in Hangzhou, with a spatula Calibrating the frustum circular mold lifting the vertical direction, at the same time, open the stopwatch to take with a ruler amount 30s The maximum diameter of the cement paste flowing in both directions perpendicular to each other, taking the average as the initial fluidity of cement paste. This is no longer pour cement paste by stirring the pot; ⑥, has been determined through the mud flow of water should be discarded, no longer stirred into the pot. When the cement paste parked, apply a wet cloth covering stirring the pot; ⑦, remaining in the cement paste stirring the pot, add water to 30,60min, open mixer, mixing 4min, cement paste fluidity measured response time of ready-mixed Anhui mortar admixture plant, high-strength materials, ready-mixed mortar admixture plant provided by the high-strength Materials Co., Ltd. Linyi City. Linyi high-strength building materials Limited (www.lygqjc.cn) located in Linyi City Hedong District One kilometer away-car supermarket North Road East.
