cement concrete (PCC) highway: Replacement with a new PCC pavement, replacement with hot mix asphalt (HMA) pavement, and cracking, seating and overlaying (CSOL) the existing pavement with HMA. Each LCA includes an appropriate maintenance schedule so that the pavements will have a 50 year life span and can be reasonably compared. The environmental
per year. Waste cement is a suitable source material for PCC production via mineral carbonation and can be recovered from waste concrete as a byproduct of aggregate recycling practices. The objective of this research was to investigate the possibility of sequestering CO 2 by producing PCC via the recovery and carbonation of waste cement calcium.

Materials. Waste sample: The flaky mica scrap (K 2 O.3Al 2 O 3.6SiO 2.2H 2 O) sample was collected from one of the mica exporter based in the Jharkhand state of India. The light-coloured soft to touch mica samples having an average size between 5 nm and 25 mm was further processed in a mortar grinder (Retch model 200 M) to produce finer sizes for the purpose of our experiment.
A Portland Composite Cement (PCC) is produced by inter-grinding the clinker with waste generated by the pharmaceutical industry, silico-manganese slag and fly ash. An evaluation of the clinker and the PCC is performed and compared with a commercially available Ordinary Portland Cement (OPC).

Abstract Shredder is the equipment used for ferrous scrap grinding that enables the recycling of steel in steel mills. The scrap is mostly originated from end-of-life vehicles (ELV).Therefore, this residue is known as automotive shredder residue (ASR). Throughout the world, is estimated that more than 25 million vehicles turn into an ELV every year, and most of their resources end up in ...
