Reuse of Construction and Demolished Concrete Waste

From the building site, concrete wastes were composed by big blocks and the crushing into small elements and better mixing with molding were required. The recycling of the C&D concrete wastes was conducted at TRINITAS GROUP LTD, a company specialized in producing concrete blocks with natural sand and aggregates with a mixing design of Therefore, eco-friendly reclamation approaches to recycling concrete waste into sustainable building materials has been developed, and the collected concrete waste is commonly prepared into recycled materials and further reutilized in new cement concrete products. Portland cement, waste glass, and iron slag have been Sustainability Special Issue : Recycling of Concrete Wastes

Capacity to Develop Recycled Aggregate Concrete in South

The global sustainable construction aimed to minimize the ecological impacts of constructed facilities’ lifetime. In construction, concretes are the major materials utilized in South East Asia. Thus, it makes environmental and economic sense to utilize recycled materials in the production of new concretes for diverse uses. This review Recycled cement was produced through burning a 2-year-old waste cement paste at 4 different temperatures (120 °C, 450 °C, 750 °C and 1150 °C) and then grinding into powder. The selected temperatures were the temperatures where there was a significant weight loss based on the thermogravimetric analysis (TGA) result of the old Recycled cement ScienceDirect

Multirecycled concrete aggregates in concrete production

From the third generation onward, the produced concrete is basically mortar. However, the number of recycling cycles could increase with equivalent addition of new natural aggregate (NA), which is both advisable and rational, given the limited of waste material available. 12.2. Multirecycled concrete aggregates. 12.2.1.The concrete construction and demolition waste (CDW) is usually recycled as coarse aggregate. The fine fraction remains unused if recovered at all, it is for downcycling in backfilling. Part 1 of this article is dedicated to a technical study on recycling of the waste concrete powder (WCP) as supplement in blended cements.Open Access proceedings Journal of Physics: Conference

Recycling of concrete ScienceDirect

The results highlight that the concrete recycling system can reduce 99% of the EMF and 66–93% of the FMF compared with the baseline system, in which concrete waste is landfilled. All three recycling modeling approaches indicate that concrete recycling can considerably reduce EMF and FMF compared with the baseline system, primarily EOL fates involving burning of plastic waste were found to be hotspots for CC. In India, open burning, incineration and cement kilns accounts for 8% of plastic waste EOL while contributing to 38% of total CC. In Indonesia, open burning accounts for 36% of plastic waste EOL, but contributes to 91% of total CC.Life cycle assessment of plastic waste end-of-life for India and Indonesia

Chemical recycling and use of various types of concrete waste

The theories of techniques for recycling and reusing concrete waste by using chemical methods tend to take advantage of the characteristics of concrete waste. Concrete contains ∼70% aggregates and ∼30% hydrated cement. The aggregates are small stones and sand, which are chemically inactive.Huge number of studies have been primarily focusing on the reuse of concrete waste as aggregate. It is a viable alternative for concrete production, which can reduce depletion of natural resources, avoids waste disposal in landfills and preserves environment [4], [5], [6], [7].The concept of complete recycling of construction and Quality improvement of recycled concrete aggregate by
