Concrete of new technology to reduce carbon emissions

As one of the main causes of global warming, carbon dioxide has been the focus of international climate and environmental issues. In recent years, the world Conference on the prevention of global warming has been held every year. It can be seen that how to further strengthen the reduction of carbon dioxide emissions is an urgent need to deal with global climate change.



 A six-year, $20 million competition to capture Carbon dioxide emissions from running power plants and turn them into useful products has ended, foreign media reported. The competition produced two winners.

Canadian startup CarbonCure Technologies was one of the winners with a technology that pumps a highly specific amount of captured carbon dioxide into a concrete plant's resorter system and reacts with calcium ions in the cement to form a nanosized mineral, The mineral can be incorporated into concrete mixtures and increase their compressive strength by 10%. Another winner is from the university of California, Los Angeles (UCLA) CarbonBuilt team, its technology involved or cement plant of smoke in the air from the plant to capture carbon dioxide, and injected directly into the concrete mixture, it turn carbon dioxide and permanent storage, according to introducing, this method can reduce the carbon footprint of concrete by more than 50%, And reduce the amount of regular Portland cement needed by 60 to 90 percent, and best of all, it produces concrete that is just as strong and durable as conventional concrete.

Not only did the two winning teams prove that their methods could eliminate meaningful CARBON dioxide, keep their own CARBON footprint, land, water and energy use to a minimum, and produce concrete with compressive properties equal to or better than conventional materials, And this is also the concrete new technology from the conjecture to really can put into use important indicators.

Concrete, as a commonly used building material in civil engineering industry, plays a decisive role in ensuring the safety of building structure and the follow-up delivery period. Therefore, a series of performance tests are required for new concrete materials before they are put into use. According to GB/T 50107 concrete strength inspection evaluation standard, GB/T 50081 "standard of physical and mechanical properties of concrete test method" and other relevant concrete test standard, all the r&d and production test of microcomputer control hybrid servo pressure testing machine, robot automatic concrete pressure testing machine, etc., to meet the demand of concrete compressive strength test.

 This testing machine is suitable for the compressive strength test of cement, concrete and rock. With appropriate fixtures and measuring devices, it can also meet the splitting test and static compression elastic modulus test of concrete, and can expand multiple displacement measuring channels according to user requirements.



WANCE robotic automatic concrete compression testing machine is mainly composed of servo hydraulic compression testing machine, six degrees of freedom manipulator, pneumatic clamp, vision system, servo control system, hydraulic system and so on, to achieve the testing machine intelligent and automation, the whole process without the participation of test personnel, greatly improve the work efficiency.

Concrete is one of the most abundant materials in the world and an important frontier in the fight against global climate change. Through the Carbon Xprize competition, we learned how to use new technologies to avoid and reduce emissions from heavy industry, which is also a trend in the global fight against climate change in the future. As a supplier of material mechanical properties test program, Wantai also hopes that in the future, there will be more new technologies that can effectively reduce carbon emissions while ensuring material properties, so as to minimize the harm of greenhouse effect on earth organisms.
