In order to achieve the goals of 'Sustainable Development', alternative (secondary) materials are being increasingly used as bulk-fill aggregate within pavement construction as substitutes for… Expand

Decomposed granite is one kind of material used as a construction aggregate. Decomposed granite is usually obtained from weathered stone sources and then is mechanically crushed to form a course gravel-like consistency.

Crushed concrete aggregates also called as recycled concrete aggregates are fragments and pieces of concrete buildings which are demolished or rebuild. These crushed concrete are cleaned from dirt and broken to smaller pieces to manufacture aggregate which is termed as recycled aggregate. Crushed concrete aggregate eliminates the need for ...

The construction industry uses large quantities of raw materials, such as aggregates and crushed rocks, and this significantly depletes the sources of natural aggregates.

Replacing the components of concrete like cement and aggregates with these alternative materials will help in saving energy and reducing the carbon footprints across the globe.

This predicament leads the researcher to look for possible substitutes for natural aggregates particularly sand by investigating the potential use of sawdust as alternative for sand as fine aggregate in a concrete mixture.

Recycling flexible pavement generates huge quantities of Reclaimed Asphalt Pavement (RAP) aggregates, which are sometimes deserted in landfills or open dump yards. Use of this otherwise waste material in concrete may be a viable option to reduce both the ever-increasing demand for natural aggregates and minimize the landfill area …
