Plastic wastes (LDPE type) were melted at temperatures between 180˚C-250˚C in a closed system and mixed in different proportions (70:30, 60:40 and 50:50) with granite-dust, sand and clay to ...
Recycled aggregates (RA) from construction and demolition waste (CDW) instead of natural aggregates (NA) were analysed in the manufacture of new eco-friendly concrete. Fine (FRA) and coarse (CRA) recycled aggregates were used in different percentages as substitutes of natural sand and gravel, respectively. The results revealed that the use of RA in …

Such is the quality of the recycled sand and aggregates it extracts from C&D waste, its 100 per cent recycled sand is BSI-approved for structural concrete. Current concrete strength specifications allow for …
recycled aggregates prohibited the exploitation of natural resources to a great extent. As the government banned the extraction of river sand in India, it was of utmost requirement to have some alternatives of river sand. As per the market survey and observation, manufactured sand (MS) has been introduced in the con-

Highlights Mineral processing has been long applied to CDW recycling, although few researches focus on the production of recycled sand. The sand fraction originally present in crushed C&D waste represents around 50% of the total waste. This paper presents a technology that permits the production of high quality recycled sand. The total comminution …

The present study investigates the use of PET as a replacement for sand in concrete. In this study, a concrete mix with a 28-day compressive strength of 35 MPa was prepared, and then natural sand was replaced by 10%–50% of crushed recycled plastic to determine the impact of substitution levels on concrete properties.
