RXSOL-67-6706-220 Cement retarder recommended for piling and mass concrete pours with improved cohesion and temperature control.
Application
RXSOL-67-6706-220 used as concrete retarder, water reducing agent. Specifically developed by use in high quality concrete for workability retention at low water content. Also sodium gluconate as a retarders keep concrete workable during placement and delay the initial set of concrete. This is an additional admixture which uses in mortar/concrete to Provides good pumpable concrete.
These admixtures slow down the hydration process. They may also reduce the setting time of cement. Retarding admixtures fall into two categories: regular and extended-set. Regular, most commonly referred to as just “retarders,” are used to place concrete in hot climates when long travel times are expected or, in cases of emergency, when placement is delayed. They are also commonly used for mass concrete pours to prevent cold joints. Extended-set control admixtures are those used to delay hydration for many hours or even days. These are usually two-component admixture systems. The first component is a retarder (stabilizer) which delays the setting of concrete. The second component is an accelerator (activator) which overcomes the retarder. The concrete typically reaches the initial set in a few hours after the activator is applied. In the precast industry, retarding admixtures are also used as surface retarders. Surface retarders are used in making exposed aggregate architectural precast. They are typically sprayed or rolled onto the forms. The concrete is then cast into the forms. The next day, the retarded cement is water blasted or brushed off the concrete’s surface, producing an exposed aggregate finish.Precautions
Advantages of using RXSOL Cement Retarder Admixture:
- Retarding admixtures extend the setting time of concrete and maintain the workability and cohesion for extended period of time
- In the large construction projects, concrete retarder prevents cold joints formation in successive lifts and make concrete workable throughout the concrete placing
- With the use of concrete retarders, you can compensate for the accelerating effect of high temperature towards the initial setting time and minimise risks of long-distance delivery in hot weather.
- Use of retarding admixtures improves pumpability of concrete by delayed setting period and improved workability of concrete.
- Concrete retarders help to reduce segregation and bleeding in concrete in which poor sand grading is unavoidable.
- It improves the workability of concrete.
- The appearance of the concrete is greatly improved.
- Drying shrinkage and creep rate are also increased.
Good control of water content and setting time helps concrete to gain full strength and power. Our WATER Reducing Super Plasticiser RXSOL-67-6706-220 is absolutely free from CHLORIDE content.
Proper doses of WATER Reducing Super Plasticiser RXSOL-67-6706-220 ensures that workable in excess 3 hours at +20°C. Workability loss is dependent on temperature, and on the type of cement, the nature of aggregates, the method of transport and initial workability.
Concrete should be properly cured particularly in hot and dry climates.
Stock and disposal control :::
Super Plasticiser RXSOL-67-6706-220 leakage and spilage can be controlled by absorbent saw dust and excess materials can be shift to other suitable container. And after stripping and absorption area can be flushed with water.
