More Details· The enzyme essentially pulls CO 2 from the atmosphere and forms calcium carbonize crystals that can quickly fill in small cracks—keeping larger cracks that require repair work from forming. "We spray a solution that is composed of enzyme, water and calcium," Rahbar says. "We then can blow CO 2 and fill the cracks in minutes, or use ambient CO 2 that will take longer to heal the cracks."
More Details· Concrete is the most widely used construction material in the world being cement one of its main components. Cement production accounts for 5-8% of anthropogenic CO 2 emissions into the atmosphere. Most of the world''s infrastructures are produced from reinforced concrete and cracking is one of the major drawbacks for its durability.
More Details2.1 Climate Change and Concrete Concrete is one of the most used building materials in the world, and therefore needs to be produced in high volumes. In 2016, concrete production generated about eight percent of the total global carbon dioxide emissions, and 90% of that total is due to cement production (Rodgers, 2018).

More Details· A variation of this process can be used to convert calcium carbonate (CaCO 3) into calcium hydroxide (Ca(OH) 2), which can then be used to make Portland cement without producing any greenhouse gas emissions. Cement production currently causes 8 percent of global carbon emissions.
More DetailsINTRODUCTION Concrete is widely used as construction material around the world due to its resistance, durability and low cost in comparison with other construction materials (1,2). However, it is susceptible to undergo deteriorations due to diverse physico-chemical and biological factors (3,4). These factors induce formation of cracks in internal structure of concrete causing irreversible ...
More DetailsThe invention relates generally to a cement or gypsum composition having improved properties, which is prepared by incorporating an enzyme into a cement material such as a cement, mortar, or concrete, or into a gypsum product. The invention also relates to methods of manufacturing improved cement compositions and gypsum products, methods of improving the compressive strength of cement ...
More Details54 mins ·. Concrete production is now responsible for nearly a tenth of global greenhouse gases – to put it another way, if concrete were a country, it would be second only to China and the USA in CO2 emissions. This new development is certainly a huge step in the right direction. Using an enzyme normally found in red blood cells ...

More DetailsEnzymes as drugs have two important features that distinguish them from all other types of drugs. First, enzymes often bind and act on their targets with great affinity and specificity. Second, enzymes are catalytic and convert multiple target molecules to the desired products. These two features ma …
More DetailsThis study investigated effects of cement dust on antioxidant enzymes activities of Obajana Cement factory workers. Sixty (60) workers in different units/sections exposed to cement dust and controls (unexposed to cement dust) were used for this study. Colorimetric method was used to analyze superoxide dismutase and catalase.

Commonly referred to as pectic enzymes, they include pectolyase, pectozyme, and polygalacturonase, one of the most studied and widely used [citation needed] commercial pectinases. It is useful because pectin is the jelly-like matrix which helps cement plant cells together and in which other cell wall ...
