Recyclability of recycled concrete products in cement
5TH INTERNATIONAL CONFERENCE ON TECHNOLOGIES & BUSINESS MODELS FOR C IRCULAR ECONOMY: BOOK OF ABSTRACTS, 2022 This research addresses the recycling possibilities of a concrete product that contains coarse concrete aggregate as recycled material. The use of this finely milled product is proposed as an active addition to cement that already includes by-products in their composition.

Recycled Concrete as Aggregate for Structural Concrete Production [PDF]
Sustainability, 2010 A comparative analysis of the experimental results of the properties of fresh and hardened concrete with different replacement ratios of natural with recycled coarse aggregate is presented in the paper. Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns. Three types of concrete mixtures were

Recycled Flexible Resins in Concrete [PDF]
Polymer Journal, 1997 Depolymerization of poly(ethylene terephthalate) (PET) waste was performed in presence of manganese acetate catalyst. Different ratios of diethylene glycol (DG) to propylene glycol (PG) was used for glycolysis. The weight ratio of PET to the glycols mixture was 1:0.65. The hydroxyl value of the glycolyzed products were determined and the amount of free

USE OF RECYCLED CONCRETE AGGREGATE IN CONCRETE: A REVIEW
Journal of Civil Engineering and Management, 2013 The use of recycled concrete aggregate (RCA) in concrete as partial and full replacements of natural coarse aggregate is growing interest in the construction industry, as it reduces the demand for virgin aggregate. In addition, the use of RCA leads to a possible solution to the environmental problem caused by concrete waste and reduces the negative ...

Study on Recycled Concrete Powders as Mineral Admixture in Recycled Concrete
IOP Conference Series: Earth and Environmental Science, 2019 Abstract The process of recycling waste concrete generated fine powders with a particle size of less than 0.16mm; it contains a large amount of hardened cement and unhydrated cement and has high activity. In order to meet the requirement of sustainable development in concrete industry, this study aims to improve the recycle use level of ...

Concretes with nanoadditive of fired recycled concrete
Nanotechnologies in Construction A Scientific Internet-Journal, 2020 The practice of using recycled concrete from the broken concrete of substandard reinforced concrete products can become widespread in practice. The undoubted relevance of this topic is explained by the program for the renovation of the housing stock in the city of Moscow, which provides for the demolition of 5-storey residential buildings until 2032 ...
