WATER Reducing Super Plasticiser

Retarders keep concrete workable during placement and delay the initial set of concrete.

Product Description: 

Cement retarder largest supplier in Fujairah - Middle East, Muscat Sohar Oman. RXSOL-67-6706-220 product classified as WATER Reducing Super Plasticiser with superior high range water reducer for high quality rheoplastic concrete and hydration control. Specially formulated for concrete with supplementary cementitious materials like GGBS, Microsilica, Fly ash.. We are keeping ready stock of WATER Reducing Super Plasticiser RXSOL-67-6706-220  at our FUJAIRAH Branch and Mumbai unit. 

RXSOL-67-6706-220 Cement retarder recommended for piling and mass concrete pours with improved cohesion and temperature control.

Retarding plasticizing admixtures not only delays the setting of the cement but are also efficient plasticizing water-reducers. They are used to give workability retention to the concrete, delay the setting time and increase initial workability.
 

 

Retarding admixtures are used to slow down the speed of the reaction between cement and water by affecting the growth of the hydration products and/or reducing the rate of water penetration to the cement particles. The factors influencing the degree of retardation are water-cement ratio, cement content, C3A and alkali contents present in the cement, type and dosage of the concrete retarder, and the stage at which the retarder is added to the concrete mix itself.
Product 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.

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.

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.

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.

Remarks: 

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.
