Evaluation of the Effects of Crushed and Expanded Waste Glass .

Nov 25, 2017 . As a control group, a concrete specimen with natural fine sand is prepared, and its characteristics are compared with those of the specimens containing crushed and expanded waste glass aggregates. The obtained results support the usability of crushed and expanded waste glass aggregates as.

environmental impact of concrete recycling, coming from .

This paper presents the results of a research study on the environmental impact produced by the recycling of concrete originating from construction and demolition waste (C&DW). The aim of the study was to implement a life cycle inventory (LCI) of the concrete recycling phases. It was carried out in Spain, with data collected.

Mechanical Properties of Concrete Containing . - AIP Publishing

As one of the most important solutions to environmental and sustainability issues, recycling aggregates instead of using natural aggregates can limit the damage of construction activities to the environment. Therefore, the utilization of concrete that contains recycled concrete aggregate (RCA) and ceramic waste as coarse.

Construction and Demolition Waste Conference 2017.

Project Waste. Management. Plan. Our Aim is to recycle all arisings. i.e. “ZERO WASTE TO LANDFILL”. As Concrete makes up over 90% of the waste it is essential that the building is completely free of soft strip material prior to mechanical demolition. This enables the concrete arisings to be suitable for crushing and re- use.

Electro-fragmentation for the selective crushing of steel fibers .

Jul 21, 2017 . The works previously carried out during the HISER project have showed that electro-fragmentation technology is effective for the selective liberation of the steel fibers in reinforced concrete waste.
