What is White Cement? Use and properties
White cement is available throughout in North America. The manufacturing process of white cement to confirm a number of American Society for Testing Material ASTM. ASTM specification for white cement could be read as follows: cement should be white Portland cement confirming as per standard specification (ASTM C150). white cement is more expansive and costly than ordinary Portland cement because of changes in the manufacturing process and the material used. The cost of white cement is more than four times that of Ordinary Portland cement. The compressive strength of white cement is less than OPC cement.
What is Green Concrete? It's Material and Application
Green cement is known as sustainable construction material as it leaves noticeably less carbon foot prints than conventional cement when it comes to its manufacturing and usage. The composition of green cement consist of 95% recycled fly ash and 5% renewable liquid additives. The functional properties of green cement is almost similar to the conventional cement. Additionally, cement uses 20% less water compared to conventional cement. The market of green cement and concrete is at it nascent stage but it expected to witness steady growth in the forthcoming future.
Construction Green Cement To Become Billion Dollar Industry in Next Few Years
The industries across the globe are continuously engaging themselves in enhancing environmental sustainability and maintain a pollution free zone in the vicinity. The cement industry is one of the major industries in CO2 emission, accounting for more than 5% of global CO2 emission. The key reason behind the emission is the decarbonation of limestone as well as the enormous amount of energy needed to heat the raw materials.
Why cement emissions matter for climate change
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is only behind water as the planet's most-consumed resource.
