Comparison of Environmental Effects of Steel

2005/06/02In order to create an environmentally-conscious building, the environmental impacts of the entire service life must be known. Life-cycle assessment (LCA), which evaluates the impacts from all life-cycle phases, from "cradle to grave," is the best method to achieve this goal. Get price

Energy absorption characteristics of cement

2017/12/31Cement-soil has been widely used for engineering application. However, no attention has been paid to the energy absorption characteristics of cement-soil under impact loading. In this paper, a series of split Hopkinson pressure bar (SHPB) tests have been conducted to explore the energy absorption characteristics of cement-soil, and the effects of confining pressure (from 0 to 2.0 MPa) Get price

The Environmental Impacts of Concrete

• Production of one tonne of cement results in 780 kg of CO2 • 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.Get price

Drying response of lime

2019/06/10When rain impacts a building faade, it is essential that once it has entered, it leaves by evaporation to help the building dry out. Accumulation of moisture can lead to internal dampness, mould and decay of valuable masonry by salt weathering.
