Polycarboxylate belong to surfactants, polycarboxylate superplasticizer production, the surfactant molecules hydrophilic groups and hydrophobic groups of two parts, a hydrophilic group after adding water point solution, the hydrophobic group Mission directed air, liquid and solid non-polar alignment as to form a film directed adsorption reduce water surface tension and interfacial tension between two phases. The basic mechanism is that when the cement slurry was added water reducer, superplasticizer molecules adsorb hydrophobic groups oriented to the cement particle surface and lower surface energy. Hydrophilic groups point to the solution, the surface of cement particles single molecule or molecules adsorbed film is formed, the surface of cement particles to bring the same charge, showing the repulsive force between superplasticizer molecules adsorbed on the surface of cement particles steric repulsion of cement particles are dispersed, destroyed the cement flocculation, releasing large amounts of free water, increasing the fluidity of concrete mixture. During the test, if found concrete mixture workability is good, and when the slump loss does not exceed 50mm, can discharge. If it is found concrete mixture stirred bleeding occurs in the pulp, Fujian polycarboxylate water reducer, and grip (slurry bleeding to the surface, and close to the ground sinking sand, Polycarboxylate wholesale, difficult Shovel move), to see the situation after 1h, if no segregation after 1h, when the slump loss by no more than 50mm, can be as qualified to notify discharge; if after 1h concrete mixture also segregation, Description doped excessive water reducer, according to the slurry effluent from the mixing material size decreased by 0.1% ~ 0.3% of the content (within a distance of 50mm to take 0.1 percent from 0.3 percent in taking more than 120mm, the median Take 0.2%) and then redo, then unloading Eligible. If it is found by the time of the loss is too large concrete mixture should be returned (explanation of certain ingredients superplasticizer with cement or fly ash suited), please factory reformulation test again until qualified before use. This year, some cement manufacturers in order to save costs, the use of some industrial waste gypsum or anhydrite, efficient polycarboxylate water reducer, resulting in excessive slump loss, should promptly communicate with cement mix was home over time, adding the above prohibition minerals.
