ProMatrix 90
DESCRIPTION
ProMatrix 90 is a new generation superplasticiser for concrete. It contains polycarboxylate ether polymers and is specially formulated for ready-mix concrete where slump retention, high strength and durability are required in hot climates. The excellent dispersion effect makes ProMatrix 90 the ideal admixture for the ready-mix concrete industry. The ability to work with low water /cement ratios and still obtain extended slump retention allows for the manufacture of high quality concrete. ProMatrix 90 is free of chloride and complies with MNS ASTM C 494/C 494 M, and is also compatible with all cements meeting recognised international standards.
RECOMMENDED FOR
• faster mixing logistics during large jobs
• highly durable concrete
• ready-mixed concrete
• mass concrete
• long distance transport
• pumped concrete
• hot weather concreting
• concrete with less water content than with conventional admixtures

APPLICATION
Dispensing
ProMatrix 90 is a ready-to-use admixture to be added to the concrete mix as a separate component. Optimal mixing water reduction is obtained if ProMatrix 90 is poured into the concrete mix right after the addition of the mixing water. Avoid adding the admixture to the dry aggregates. A separate dispenser and feed line must be used.
DOSAGE
Dosage of ProMatrix 90 depends on the mix design, ambient conditions and degree of water reduction and workability required. ProMatrix 90 is dispensed at a rate of 1.0%-2.0% of cementitious material. Other dosages may also be used depending on the specific working conditions. Trial mixes should be made with job materials to determine the optimum dosage required for a specified job requirement.
PACKAGING
ProMatrix 90 is available in 900KG IBCs or by bulk delivery.
SHELF LIFE
ProMatrix 90 can be stored for 12 months if stored at a temperature above 5ºC and in tightly sealed original containers. If frozen, thaw it and completely reconstitute by mild agitation. Do not use compressed air.
PRECAUTIONS
Health: ProMatrix 90 does not contain any hazardous substances requiring labelling. It is safe for use with standard precautions followed in the construction industry, such as use of hand gloves, safety goggles, etc. For detailed Health, Safety and Environmental Recommendations, please consult and follow all instructions in the product Material Safety Data Sheet.
