Specialty cement technology-Rapid set CSA cement, High performance of concrete and mortars

Image
CSA cement, full name is Calcium Sulfoaluminate cement, was invented and developed in China since 1970's. It is 100% cement, get ready to use. As the third generation of cements, it is widely used on construction for decades in China. The cement has been used on concrete for bridges, airports, concrete road repair, winter construction and many other applications where early strength and time needed.As well as high strength concrete, high performance of mortars, like Self levelling compounds,tile adhesives,Non shrinkage grouts,etc. The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate and dicalcium silicate. Suitable gypsum and 0-10% limestone shall be blended with clinker during manufacture of rapid-hardening sulphoaluminate cement. The rapid-hardening cement product is hydraulicity binding material. It has high early strength. The code no is R-SAC. Specific surface are...

CSA Expansive agent - Shrinkage compensating cement additive

CSA Expansive agent / Cement additive / Shrinkage compensating cement additive  High-efficiency CSA expansive agent is obtained by blending suitable natural anhydrite with a specially manufactured clinker which consists essentially of calcium sulphoaluminate and CaO. CSA expansive agent is always mixed with ordinary cement. When mixed in the proper proportions with ordinary cement and hydrated, cement mortar or concrete expands during the early stages of hydration. This expansion, when restrained, makes it possible to minimize drying shrinkage. Moreover, when the ratio of shrinkage reducing admixture to ordinary cement is increased its high expansion qualities make it ideal for use in prestressed concrete. High-efficiency shrinkage reducing admixture is being used in all sections of the construction fields and by a wide variety of concrete products manufacturers. Expansive Cement Additive is used to chemically pre-stress concrete, providing compensation for drying shrinka...

CSA Self-Leveling Material

CSA Self-Leveling Material     General characteristics CSA cementitious self-leveling materials consist of a blend of selected cements, superplasticizer, and aggregates modified with polymers and flow agents. It is used in conjunction with Polar Bear Primer. Polar Bear cementitious self-leveling materials are supplied as pre-blended powder which requires only the addition of water on site to produce a self smoothing, free flowing material. These materials are designed for installation by a continuous mixer pump, but can also be applied by hand. Functionally they are divided into two categories: underlayments (CSA-II and CSA-III) and overlayment (CSA-I). Properties 1.      Fast application by pump, enables large areas of floor to be completed in a working day. 2.      Rapid hardening and curing allows speedy access for foot traffic and overlaying with carpet, vinyl etc. 3. ...
