Net zero concrete - Beton Consulting Engineers

Jan 18, 2021  Like the comminution of the kiln feed components, grinding clinker is energy intensive and inefficient. Traditionally, producing one ton of portland cement also produced one ton of CO 2 emissions. Making portland cement clinker less energy intensive. Cement manufacturers have worked for decades to reduce the embodied energy in portland cement.

PARTICLE SIZE DISTRIBUTION AND PROPERTIES OF CEMENT.

The specific surface area of the cement (area per unit mass) can be calculated from the particle size distribution parameters. The greater the slope, the narrower is the distribution. For equal specific surface area, cements with a narrower distribution have a smaller position parameter x' and thus a higher proportion of the fine particles. The ...
