Superplasticizer formulations the expanders technology development, accelerating agent expanders definition of technology transfer: the expansive agent is a chemical admixture added to the cement, when the condensation of hardening of cement, followed by volume expansion, since the shrinkage compensation and tensioned reinforced produce prestressed and fully fill the role of the cement gap. Now expansive agent market is chaotic performance 1: Addition and Low: 6 to 8 percent, its expansion rate is greater than that of UEA (commercially available) the expansion rate of 12% of the content; 2: alkali content is low: (K2O + Na2O) content of 0.3 to 0.4 percent, well below the 1.7 to 2.2% of the U-type expansive agent, its significant; 3: As the dosage to reduce, does not affect the early strength and late strength, truly the same amount instead of cement;: No increase the concrete slump loss, has a good construction performance.
