Hcsa High Performance Concrete Expansive Agent

Main Features:1. High inflation performance, 7d between the water limit expansion can reach 0.15 ~ 0.2%, 4 ~ 8 times that of ordinary expansion agent.2.Expansion rate is appropriate, the 3d water limit amount of expansion can be up to 70 ~ 80%, 7d was above 85%.3.Under the condition of unique wet, It can still maintain larger expansion.4. The performance is stable.Index100 type130 type160 typeFinenessSpecific surface area (m2/kg) a Y2002001.18mm triage (%)a 0.50.5Setting time (min)Initial setting (min) a Y4545Final set (min) a 600600Limit inflation (%)In the water 7d a Y0.1000.130In the air 21d a Y-0.020-0.010Compressive strength (MPa)7d a Y202028d a Y4038Note: the limit expansion ratio in the table is mandatory, the rest is recommendedMeasurement accuracy of 0.001 mmSet freely acquisition conditions, manual or automatic tracking continuous measurementWhere data is stored in graphics, Excel spreadsheets or text formWhen measuring the expansion and shrinkage stress of concrete changeApplication:1.make all kinds of high-grade special mortar and grouted material;2.waterproof concrete structural engineering;3.crack concrete engineering;4.crack of mass concrete seepage control;5.the use of concrete filling pile, can save material and time limit for a project.Packaging and storage:Lining with moisture-proof plastic bag packaging, net weight 50Kg
