Energy Consumption Benchmark Guide: Cement Clinker Production
1. Determine your plant’s energy use per tonne of clinker, by fuel type. (See the table on page 10 for the calculation method if these data are not readily available.) 2. Compare your plant’s per-tonne energy use with that of other cement plants (See Figure 4). 3a. If your plant energy use is equal to or better than the top

Research on Crushing Concrete Members by High-Voltage
High-voltage pulse discharge (HVPD) is an energy-saving, efficient, and green technique, which has broad prospects in concrete crushing. The finite element models of the concrete beam, slab, and column segments were established with ANSYS/LS-DYNA finite element software. Based on the principle of equal impact pressure, the shock wave generated by the fuse explosion caused by HVPD of 50

The Environmental Impacts of Concrete
• Of the total CO 2 output, 30% derives from the use of energy and 70% results from decarbonation • Important to realise is that although 5% of the worldwide generation of CO 2 is due to cement production, that level of output also reflects the unique and universal importance of concrete throughout the construction industry.

Concrete CO Fact Sheet
The process of mining sand and gravel, crushing stone, combining the materials in a concrete plant and transporting concrete to the construction site requires very little energy and therefore only emits a relatively small amount of CO2 into the atmosphere. The amounts of CO2 embodied in concrete are primarily a function of the cement content in
