Feasibility of Using Recycled Construction and Demolition Materials for Deep Soil Mixing

A study on use of recycled demolition debris in construction

The particle size distribution of output material is affected by type of crusher used .The demolition debris of particle size less than 37.5 mm. The inclusion of upto 15% of particle larger than 37.5 mm should not alter density significantly. Water absorption of coarse and fine particle of crushed brick aggregates passing 19 mm 4.75 mm respectively and retaining on 4.75 mm are 6.15 % and 6.20 %...

Laboratory Study Geotechnical Benefits of Mixing Construction and Demolition Screenings with Cement- Amended Dredged Materials

Fiber reinforced plastic composites using recycled materials

This work investigates the feasibility of using recycled high density polyethylene (rHDPE), recycled polypropylene (rPP) and old newsprint fiber (ONP) to manufacture fiber reinforced composites. The boards were made through air-forming and hot press. The effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...

Properties of Concrete Paving Blocks and Hollow Tiles with Recycled Aggregate from Construction and Demolition Wastes

In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two d...

Utilization of Recycled and Waste Materials in Various Construction Applications

More production equals more waste, more waste creates environmental concerns of toxic threat. An economical viable solution to this problem should include utilization of waste materials for new products which in turn minimize the heavy burden on the nation’s landfills. Recycling of waste construction materials saves natural resources, saves energy, reduces solid waste, reduces air and water pol...
