The developers, AET and Cemstone, wanted to design a strong concrete mix that was made from as much recycled material as possible. By analyzing the recycled concrete aggregate through a microscope, they learned there is always unhydrated cement available to form cement paste in the new "green" concrete mix.

Abstract. Recycled aggregates extracted from the construction and demolition waste of brick and concrete building are mixed recycled aggregates (MRA), which comprise concrete recycled aggregate (CRA) and brick recycled aggregate (BRA). The components of coarse aggregate used in concrete incorporated with MRA are natural aggregate (NA), CRA, and
A case study on using recycled aggregates in a construction project in Hong Kong is used to illustrate the barriers that must be overcome to facilitate the wider use of recycled aggregates in concrete in Hong Kong. Keywords: construction and demolition (C&D) waste; recycled aggregate; recycled aggregate concrete. 1. INTRODUCTION.
This initiative aims to advocate for improved packaging design for recycling, facilitating the transition to a more circular economy. The guide offers retailers and manufacturers a systematic approach to designing recyclable packaging across all types. In parallel, the WPO is diligently developing country-specific Waste Stream Mapping Guides.
🕑 Reading time: 1 minuteQuantities of materials for concrete such as cement, sand and aggregates for production of required quantity of concrete of given mix proportions such as 1:2:4 (M15), 1:1.5: 3 (M20), 1:1:2 (M25) can be
The recycled aggregate is used as soon as it is processed. Recycled concrete currently supplies about 5% of aggregate use. The bulk of recycled aggregates – about 68 % – is used as road base. The remainder is used for new concrete mixes (6%), asphalt (9 %) and fill. Recycling concrete features both cost savings and environmental benefits:
