Environmental and Qualitative Benefits of Supplementary Cementitious Materials

Concrete is the most widely used construction material in the world. Approximately 10 billion tons of concrete are produced each year. On average, 15% by weight of concrete is cement, and each metric ton of cement produced generates 900 kg of CO2, making cement production account for 9% of CO2 global emissions.

Options for Grinding Slag and Pozzolan for Use as Construction Materials

Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness.

Economic Evaluation of Projects

The most common way to assess the economics of a project is the discounted net present value (NPV) of cash flows. Before budgeting a new project, a company must assess the overall level of project risk relative to normal business operations. Higher-risk projects require a larger discount rate than the company’s historical weighted average cost of capital (WACC) and vice-versa for lower risk investments.
