0% cement concrete - M&R geopolymer concrete a South African first!!

High production costs of concrete in combination with the high CO2 footprint of cement has instigated the research, development and application of concrete utilizing by-products and wastes as partial or entire binder replacements. Due to the Murray & Roberts' constant pursuit of innovation and sustainability, the geopolymer concept was driven strongly as the balance between environment, social consciousness and economics. The use and removal of waste/by-products for the benefit of communities and the environment is understandable, the more difficult issue of economical feasibility was the challenge to overcome. Through research and development Murray & Roberts have overcome these hurdles, and the geopolymer concept is beginning to reach fruition. Geopolymer concrete is the first goal to be realized; with applications in the mining, precast and road industries near to fulfilment. Since the historical applications from the Egyptian and Mayan pyramids to more recent structural applications at the University of Queensland's Global Change Institute, geopolymer concrete or 0% cement concrete is evolving as an alternative structural building material to conventional concrete. Geopolymer concrete has the standard beneficial properties of conventional concrete blended with the control mechanisms of resin-based materials while reducing by-product and waste materials that are increasing in quantities far beyond current needs across all industries. Additional benefits surmounting conventional concrete's limitations can be engineered into the geopolymer such as thermal shock resistance for smelters, additional bond strength for shotcrete applications, acid-resistance for high durability waste water treatment works and/or air-curing for convenience. These applications enhance Murray & Roberts' core values of Care, Integrity, Respect, Accountability and Commitment while aligning to our business principles of being South Africa's leading engineering, contracting and construction services company that subscribes to good corporate governance, good corporate citizenship and ethical business practices. The extended use of these by-products and wastes has also been a personal goal for the past 15 years with the incorporation of ARC technology to extend conventional concretes up to 85% with by-products to enhance durability and strength while reducing the massive impact of the construction industry on the environment. ======================================= www.Concrete.TV Facebook:   / concre.  .
