PSC has many superior performance characteristics which give it certain extra ...
Portland slag cement is obtained by mixing Portland cement clinker, gyplum and Ifanulated sla,in suitable proportions and grinding the mixture to get I thorough and intimate mix between the consti tuents. It may also be manufactured by separately grinding Portland cement clinker, gypsum and granulated slag and then mixing them intimately.
— Maximal substitution of Portland cement clinker with these materials could have avoided up to 1.3 Gt CO2-eq. emissions (~44% of cement production and ~2.8% of anthropogenic CO2-eq. emissions) in ...
— Ordinary Portland cement, alkali-activated slag cement, and geopolymers represent three different cementitious materials with their own characteristics and properties. These three types of materials have been extensively considered in the last 10 years. However, only specific studies about one type of cement have been considered.
• Ordinary Portland Cement (OPC) is versatile, ... OPC cement is manufactured by grinding clinker, gypsum, and other materials like limestone, fly ash, or slag to a fine powder. This type of cement is known for its versatility and is used in various construction applications, such as building foundations, bridges, roads, and many other ...
Portland slag cement (PSC) is a cement type made by mixing Portland cement clinker, gypsum, and granulated blast furnace slag in a specific ratio before grinding. The key ingredient in the making of PSC is blast …
Heidelberg Materials Slag Cement and portland cement are both hydraulic cements that harden by chemically reacting with water to produce calcium-silicate hydrates (CSH), the primary binding agent in concrete. Heidelberg Materials Slag Cement reduces excess calcium hydroxide [Ca(OH)2] by producing more CSH.
Slag cement was the most effective at increasing the solar reflectance. The albedo values increased with increasing amounts of slag cement, and the highest obtained value was 0.582 at 70% replacement of Portland cement with slag cement. The next best material to increase solar reflectance was white sand followed by latex.
— Portland Slag Cement (PSC), because of its lowest carbon footprint compared to other commercially available cement such as OPC, Portland Pozzolan Cement, Portland composite cement, Portland Limestone Cement, and others, can be considered as an appropriate cement in the present scenario. PSC is produced when …
For instance, one combination of portland and slag cement, in combination with a highly reactive aggregate may need as much as 70 percent slag cement to mitigate ASR, while a less reactive aggregate, combined with a lower alkali cement and slag cement may only need 25 percent.
