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...

Concrete Road Urgent Repair Material Concrete repair mortars, Pavement repairs, concrete repairs, fast cement repair works This material is the easy and fast way to repair concrete pavements, bridge decks, industrial floors, highways, airport runways,etc. 1. Special applicator was not necessary while operating, just need mixed repair material, sand and crushed stone with water in designed ratio, so convenient for operating. 2. This product can ensure working life more than 20mins with a higher strength. From mixing, concrete road surface resume working just need 4 hours, so it is an ideal urgent repair material for airport and expressway, etc. 3. For based on special rapid-hardening sulphoaluminate cement, this product have excellent sulfate-resisting and seawater, also can avoid the damage from alkali aggregate reaction. 4. Low rate of batch water with its slight expansion make this material have a high degree of compaction beside excellent capacity ab...

A Special Additive for Cement Mortars

Image
CSA binder is a hydraulic binder based on sulfo-aluminate cement, rather than calcium aluminates which are the basis of Calcium Aluminate Cement (Fondu cement) or Calcium Silicates which are the basis of Portland Cement. CSA binder is used in formulated products either as a hydraulic binder by itself or with the addition of Calcium Sulphates or in combination of Portland cement. When used as an additive, the following properties can be developed, such as: Fast setting time, Rapid hardening, the early strength and final strength gains, lower alkalinity (PH value), Good expansion value, Cracking resistance, corrosion resistance, it can also worked in low temperature. CSA binder can be applied to a wide range of products: Fast setting cement and mortars Rapid repair mortars Fast set tile adhesives Self levelling compounds Self smoothing mortars Non-Shrinkage grouts Water stopping mortars Glass Fiber Reinforced Concrete (GRC), etc.
