Review Use of Demolished Concrete in Pavement Construction

Abstract

Recycled aggregates consist of crushed, graded inorganic particles processed from the material that have been used in the constructions and demolition debris. The target of the present thesis work is to determine the strength characteristic of recycled aggregates for the application in concrete pavement construction. The scope of the thesis is to determine and compare the compressive strength, flexural strength and sulphate resistance of concrete by using different percentages of recycled aggregates. The investigation was carried out by using workability test, compressive strength test, flexural strength test and sulphate resistance test. A total of five mixes with replacement of coarse aggregates with 0%, 10%, 20%, 30% and 40% recycled coarse aggregates were studied. The water cement ratio was kept constant at 0.38. It was observed that workability of concrete was decreased with the increase in recycled aggregates in concrete. For the strength characteristics, the results showed that the strengths of recycled aggregate concrete were comparable to the strengths of natural aggregates concrete. I.

Use of Construction and Demolition Waste Material for Soil Stabilization

“…Kumar and Rathod, (2018) reviewed several literatures and finally suggested the usage of C&D debris to curb detrimental effect of wastes on environment and enhance soil properties. They also suggested the use of polypropene as an economical material with high strength, longevity and non-biodegradability which in turn could improve soil properties leading to soil stabilization [9]. Bhat and Gupta, (2018) examined and analyzed the various sorts of researches on the use of C&D waste in pavement subgrade.…”
