Supplementary Cementitious Materials
Supplementary Cementitious Materials (SCMs) are materials that, when used in conjunction with portland cement, portland limestone cement or blended cements, contribute to the properties of hardened concrete through hydraulic and/or pozzolanic activity. Examples of supplementary cementitious materials include NewCem®: ground granulated blast furnace slag (GGBFS), a by-product of the iron industry, and fly ash, a by-product of coal combustion in power plants.
Supplementary cementitious materials offer sustainable and performance advantages for those who build and occupy structures of all kinds. The growing use of these environmentally friendly materials is due in part to numerous performance factors, including improved workability and consolidation, flexural and compressive strengths, pumpability, resistance to chlorides and sulfates, lower temperatures for mass concrete, mitigation of alkali silica reaction, and decreased permeability.
The use of cementitious blends not only results in stronger, more durable high-performance concretes, but also helps reduce global climate impact by lowering energy consumption and greenhouse gas emissions.
These materials provide a significant contribution to sustainable construction. The use of these materials in concrete production consumes less energy and offers improved efficiency and building performance. These materials can contribute to the achievement of LEED (Leadership in Energy and Environmental Design) points.
