‘Green’ research results in new geopolymer concrete technology
Inorganic polymer concrete (geopolymer) is a new kind of cement materials using “fly ash, one of the most abundant industrial products on Earth, as a substitute for Portland cement, the man most widely produced in the artificial material land.
Portland Cement production is a major contributor to CO2 emissions as a percent estimated five to eight of all human beings around the world generated by the atmospheric CO2 stems from the concrete industry. Portland Cement production is currently Toping 2.6 billion tons per year worldwide and growing at 5 percent annually.
Geopolymer concrete has the potential to substantially reduce CO2 emissions, produce a more resilient infrastructure capable of design life measured in hundreds of years instead of tens, the preservation of hundreds of thousands of hectares are currently used for the removal of products of coal combustion and protect aquifers and surface water bodies of fresh water through the disposal of fly ash landfill.
Compared with ordinary Portland cement (OPC), geopolymer concrete (GPC) offers enhanced corrosion resistance, fire resistance substantially higher (up to 2400 ° F), high compressive strength and traction, a gain of resistance fast, and lower shrinkage.
Such action is more concrete geopolymer potential life-cycle reduction of greenhouse gases, as much as 90% compared with OPC.
This technology, along with the research being carried out another important to meet future energy needs, it became clear in Louisiana Tech will have the technology to its Energy Systems Conference on November 5 at the Center for Technology Transfer in Shreveport.
