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.

WATER Reducing Super Plasticiser RXSOL-67-6706-220 High range water reducing property allows the production of high quality concrete without excessive cement contents- ensures improved durability.

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.

Difference between Cement Retarder and Cement Accelerator

Retarding Admixtures

Retarding admixtures helps and work as water reducing agent and Cemenrt retarder keep concrete workable during placement and delay the initial set of concrete. Chemically retarder slow the setting rate of concrete, are used to counteract the accelerating effect of hot weather on concrete setting. High temperatures often cause an increased rate of hardening which makes placing and finishing difficult. Retarders keep concrete workable during placement and delay the initial set of concrete. Most retarders also function as water reducers and may entrain some air in concrete. Retarder use for increase setting time of cement.

Accelerating admixtures

Accelerators make concrete set faster rapidly after mixing with concrete. This product can be added to a concrete batch either immediately before or during mixing to kick the set time of a batch of concrete into high gear and initiate setting time one to three times faster than normal mortar and concrete. On the other hand Accelerating admixtures increase the rate of early strength development, reduce the time required for proper curing and protection, and speed up the start of finishing operations. Chloride Free and Accelerating Compund for Concrete and Mortar. Accelerator is use for reduce setting time.

Accelerating admixtures are especially useful for modifying the properties of concrete in cold weather.

Note

Increasing the setting time of cement helps High workability for longer periods and if cocrete is going to pump for high rise presence of RXSOL-67-6706-220 in cement Lower pumping pressure also.

WATER Reducing Super Plasticiser RXSOL-67-6706-220 Reduced thermal peaks, Acts as a highly effective hydration control admixture especially in blended concrete.
Delayed setting with longer workability, Higher workability levels are maintained for longer than with sulphonated and naphthalene admixture.
Higher ultimate strengths, Better rheological properties for concrete made with double or triple blends without abnormal retardation.

Improved durability and Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability by reducing permeability.

WATER Reducing Super Plasticiser RXSOL-67-6706-220 is compatible with all types of Portland cements and cement replacement materials such as PFA GGBFS and microsilica.

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.

Cement reacts with water to form a hardening paste that binds the aggregate together to produce hard concrete. This hardening process is called hydration. And materials used to slowing down hydration process is called Retarder.

Best dose rate can be determined in trial batch mixes. While In normal concrete a dosage of between 0.7-2.0 litre for 100kg. total cementitious material. In a high performance, low water cement ratio concrete, a dosage of between 1.5-3.5 litre / 100kg total cementitious material to to improve strengths. The addition of the admixture will allow the removal of water from the mix whilst maintaining workability.

Higher dosage of WATER Reducing Super Plasticiser without causing any adverse effects upon the concrete. RXSOL-67-6706-220 Cement retarder is a chloride free. Superplasticising admixture based on selected polymer modified naphthalene sulphonate dispersives. RXSOL-67-6706-220 Cement retarder disperses by electro kinetic action in the concrete mix. Enable the water phase of the concrete to perform more effectively.

After initial trials. Minor modifications to the overall mix design may be made to optimize performance.

Note : Initial trials should be made with normal concrete mix designs. The use of a combination of admixtures in the same concrete mix and or cement replacement may alter the setting time. Trials should always be conducted to determine such setting times. Never mix RXSOL-67-6706-220 Cement retarder directly to cement the admixture should be added to the concrete with the mixing water.

Overdose : Always take batch trial before uses of cement retarder. High dose will increase retardation effect and more curing required, How ever this may reduce the strength of concrete. But overdosing can be done if sulphate resisting cement or cement replacement materials are used.

Why RXSOL Cement Retarder is the best?

Uses of RXSOL Cement Retarder

To improve the effectiveness of the water content of a concrete mix
To help maintain the workability of ready mixed concrete deliveries in hot weather at usable levels.
To extend working times of concrete and minimise problems of delay in transportation
Particularly suitable for use in mixes with low cohesion.

Advantages of RXSOL Cement Retarder

Water reduction significantly improve compressive strengths at all ages and enhances durability through the production of low permeability concrete
Controlled retardation extends working life and stiffening in time for ease of construction
Control of stiffening improve slip forming and assists in preventing the formation of cold joints in large pours.
Minimised transportation delay problems, maintains place ability and reduces
Slight air entrapment improves cohesion in mixes with poorly graded sands or a lack of fine material, minimising bleed and segregation.
Allows specified strengths grades to be met at reduced cement content or increased workability.
Chloride free, safe for use in pre-stressed and reinforced concrete.
