Concrete Repair Products

Melbourne, Victoria, Australia

We are offering concrete repair products . The company is a chief manufacturer, exporter and supplier of concrete repair products (crp ec30). The concrete repair product (crp ec30) is an environmental alternative to prime coats and is designed to penetrate 12mm to 25mm into the base and sub-base of stabilized imestone, gravel and caliche bases. Traditionally known as cutback asphalts, prime coats (aka. Primes), have been known to most effectively cure sub-base and base materials, while at the same time been scrutinized for its un-environmental application methods. features

• bond the hma layer to the base
• penetrates deeper than conventional emulsified asphalts, 12mm to 25mm of base
• cures and evaporates faster than traditional cut backs
• does not contain hydrocarbons
• can lay hma faster
• does not require blotter sand to absorb excess material
• dries in 2 to 3 hours
• does not require heat to maintain in applicable conditions, reducing energy costs and liability issues regarding transportingheatedtrucks, orheatedtanks in location
• dust control
• does not contain hydrocarbon related voc gases
• substantially reduced epa concerns on air and water contamination
• reduced environmental and human liability when applying inhaling handling cutbacks materials
• note : preliminary investigations have led to positive results with all requirements for the products applications; however, further investigation is needed to create a workable platform for contractor traffic after 72 hours application. Current tests indicate a degrading performance if ec-30 is applied if contractor trafficisopened immediately after application. technical data
  • boiling point (oc) : 100oc
  • specific gravity ( h20 = 1) : 1.02
  • vapor pressure : 17.535 ( gauge)
  • percent volatile : 0
  • solubility in water : miscible
  • appearance and odor : brown liquid, odourless
  • flammability : non flammable in both water based and dry state
  • guidelines for use and application : depending upon the openness of the surface to be treated and under preliminary investigation, it was concluded that desirable results were found after an application rate of 0.5 to 1 litre per square metre. Like traditional tack coats and curing membranes, the crp EC30 should be applied with well-calibrated distributors. Spray bar and distributor nozzles should be sized and set to deliver to the desire shot rate. Air and pavement temperatures should be sufficiently high to allow the emulsion to fully cure, and there should be no imminent threat of rain. storage and handling : crp ec30 is a water based suspension, and should not be exposed to freezing temperatures below 5o or overheating over 50oc. The emulsion is chemically stabilized, so care should be taken not to upset the chemicals balance with contamination by chemicals, over-exposure to air, or adverse mechanical or thermal conditions. Before being filed, tanks and trucks should be examined for possible contaminants. Tanks may be circulated top to bottom with a pump, but over-pumping is to be avoided. Recommended use and storage temperatures are given in the table. precautions : do not dilute with additional water. Do not apply when temperatures are minimum order quantity : Available in 20 Ltr 200 Ltr 1000 Ltr
