Rockconcer CD-51

Rockconcer CD-51 is a highly effective powder synthetic admixture, free from chlorides for concrete and cement mortar . It has been specially formulated for combined action as water reducing agent with acceleration in setting time.

Properties

Application & Recommendation

-Reduces initial set 2-5 hrs, depending on the dose as well as concrete temp

-Improves the workability

-Reduces water cement ratio

-Helps to achieve high early strength, hence reduces time required for removal of shuttering

-Normal Portland cement can be used instead of rapid hardening cement, thereby reducing cost

-Extremely low dosage (0.15% of weight of cement)

AREAS OF APPLICATION:

. Low temperature concrete

. For pre-cast concrete

. For All grades of concrete requiring high early strength

. Concrete brick / block manufacturing unit

. Floor slabs, roads and runway pavement, where early strength development is required

. Under water concrete / tremie concrete.

METHOD OF APPLICATION:

1- The correct quantity of Rockconcer CD-51 should be measured with recommended dispenser and should be thoroughly dispersed with approx 25% of the recommended water content (based on mix design by weight )

2- Mix concrete constituents along with balance approx .75% of the recommended water content (based on mix design by weight) for 3 minutes.

3- As soon as step 2 is over , the admixture dispersed in water (as in step 1)is to be added to the wet concrete and mix it further for 2-3 minutes to get a homogeneous mix.
