Product Technical bulletin

Cement retarder – 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.. 



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.

Dose : 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. 

Feature :

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.

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.

 

CEMENT BONDING Chemistry : 

Cement Chemistry with water for SETTING :

Cement contains C3S,C2S,C3A,C4AF

And C3A is responsible for initial setting because it react first from the water after addition .

Respectively heat of hydration can be serialized as follows :C3A>C3S>C4AF>C2S

Here we can observe C2S responsible for Cement strength.
