is a high performance Superplasticizer admixture based on PCE polymers with long chains specially designed to enable the water content of concrete to perform more effectively.
ROBUSTO HRWRA 279 is a high performance Superplasticizer admixture based on PCE polymers with long chains specially designed to enable the water content of concrete to perform more effectively.
This admixture is effective in improving the day to day production efficiency of a concrete plant by rapidly dispersing cementitious contents in concrete mixtures, the minimizing mixing time.
ROBUSTO® HRWRA 279 is a new generation super plasticizer that is specially designed to produce ready mixed concrete. It helps in water reduction and improves the fresh concrete characteristics.
ROBUSTO HRWRA 279 is used for the following:
Trials should be conducted to determine the optimum dosage of ROBUSTO HRWRA 279 to meet the performance requirements by using the materials and conditions in actual use. However, the normal dosage ranges between 0.3 to 1.2 % by weight of total cement or cementitious content.
Robusto Chemicals provides technical advisory service for on-site assistance and guidance on mix design, optimum dosage evaluation of trials.
ROBUSTO® HRWRA 279 is an improved Superplasticizer based on advanced PCE technology which gives the following:
ROBUSTO® HRWRA 279 complies with IS 9103:1999 and ASTM C494, Type-D, Water Reducing and Retarding admixtures depending on the dosage used.
