ADVANTAGES

•  It increases the initial setting time, which helps in transportation of concrete.
• It significantly improves the workability of the concrete mix. In presence of the admixture, the slump value increases resulting in ease of placing the concrete mix.
• Addition of the admixture can reduce the water content of the concrete mix by 40% or more, which results in more dense concrete, thereby increasing the compressive strength. This improves the durability, impermeability and frost & water resistant properties of the mix.
• It decreases the amount of vibration and significantly reduces the risk of segregation.
• Economics in mix design can be achieved by reducing cement usage.

MECHANISM

When Portland cement is mixed with water, the cement agglomerates stick to each other due to insufficient mutual electrostatic repulsion. With the presence of CETEX-SPSR, the attraction between the particles is reduced and the cement particle disperse, hence a more cohesive and consistent mix is achieved.

CETEX SPSR

DIRECTION OF USE

CETEX-SPSR should be added to the concrete mix during the mixing cycle after addition of water. Never add the admixture to the dry mix.

PACKING

CETEX-SPSR is available in 25, 60 or 250 kg pack or bulk. Store in frost-free condition away from sunlight or extreme heat. For best result, use within one year.
