CSA binder CSA ,HCSA Binder is manufactured under a strict quality assurance systems GB/T 19001-2000 (i.e. ISO9001:2000) and GB/T 24001-1996 (i.e. ISO 14001:1996) CSA , HCSA Binder is normally supplied in one-ton bag which include a moister resistant barrier. However, in common with all hydraulic binders HCSA Binder must be kept from moisture, and can retain its properties for up to six months when properly stored.The properties of HCSA Binder conform to the standards of the manufacturer and to the Chinese relevant standards.Main components(%)LOSSSiO2AL2O3Fe2O3CaOMgOSO3TiO2Total0.289.8832.512.2741.931.469.611.4499.38 Fineness Specific Surface Area: according to standard GB/T 8074-2008: Usually range: HCAS>360 -430m2/kg;Standards: HCAS >360m2/kg,Hydraulic Properties The characteristics of HCSA Binder have been tested in accordance with the Chinese standards: GB20472-2006.Setting time determined at 20°C±1, using Vicat needle according to GB/T 1346-2001.Strength testing by GB/T17671-1999 Physical properties Initial setting time(min)Final setting time(min)Flexural strength(Mpa)Compressive strength(Mpa)≥25≤1801d3d28d1d3d28d≥4.4≥10.0≥11.0≥20.8≥70.0≥80.0 Reactivity with Portland cement HCSA Binder may be used in combination with other mineral products, for example Portland cement, calcium sulphates and fillers, or with organics such as polymers in latex foam or in redispersible foam.Depending on the type of mixes and technology employed, HCSA Binder can be used to obtain and control various properties.The behavior of Portland cement is vary variable. In general, acceleration of set increases progressively with the addition of HCSA Binder. The amount of HCSA Binder needed to obtain a specific setting time varies considerably depending on the origin of the Portland cement and performance can be modified with the use of additives.The strength development of HCSA Binder/Portland cement and/or Calcium Sulphates depend on the nature of the Portland cement and/or Calcium Sulphates used. In general these mixes will develop mechanical strength at a very early stage (several hours). With some type of Portland cements and in formulated products containing additives which control the setting and hydration, the long term properties is similar to those of the original Portland cement, however it is necessary to check the behavior of each Portland cement used.
