Recycling of Brick Aggregate Concrete as Coarse Aggregate

Journal of Materials in Civil Engineering, 2015
An extensive investigation was carried out for recycling of demolished brick aggregate concrete as coarse aggregate. For this, demolished concrete blocks were collected from 33 different building sites of different ages and broken into pieces as coarse aggregate.

Influence of Recycled Aggregate Defects on the Durability of Recycled Aggregate Concrete

Key Engineering Materials, 2014
An experimental investigation was conducted on the durability of recycled aggregate concretes with the water to binder ratios of 0.26 and 0.60, including chloride ion penetration resistance test, freezing-thawing resistance test and water penetration resistance.

Study on the recycling of recycled aggregated concrete

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
With the development of recycled aggregated concrete researches, and the exhausting of construction materials, it's safe to predict that wider application of recycled aggregated to engineering construction is an inevitable trend. Here a practical problem is presented whether the concrete can be recycled again when the structure constructed by recycled ...

EVALUATION OF DIFFERENT ASPECTS OF RECYCLED AGGREGATE AND RECYCLED AGGREGATE CONCRETE

Malaysian Journal of Civil Engineering, 2018
Concrete is one of the most popular and widely used construction materials in the world. Concrete provides suitable features for construction such as durability, fire resistance, satisfactory compressive strength, availability and is economic as well compared to other construction materials.

Correlation between different properties of recycled aggregate and recycled aggregate concrete

AIP Conference Proceedings, 2019
The use of recycled aggregate (RA) in concrete has been increasing popularity over the last decades. Researches have been taken place in this field to develop information about strength properties of recycled aggregate concrete (RAC). In this research, three RA samples collected from different sources were used to produce different RAC mixes to ...

Durability of recycled aggregate concrete prepared with carbonated recycled concrete aggregates

Cement and Concrete Composites, 2017
Abstract The mechanical properties of recycled aggregate concrete (RAC) incorporating carbonated recycled concrete aggregates (RCAs) have previously been reported. However, the durability of RAC prepared with carbonated RCAs remains to be accessed. In this study, the durability properties of RAC prepared with non-carbonated RCAs and carbonated RCAs ...

Durability of Recycled Aggregate Concrete

2014
Recycled aggregates (RA) are now well-known to be suitable for structural concrete production. The employment of RA (obtained from concrete or ceramic waste) in recycled aggregate concrete (RAC) production as a structural material has been widely analysed and validated in many applications.

Effects of Recycled Aggregate Characteristics on Performance Parameters of Recycled Aggregate Concrete

SP-192: 2000 Canmet/ACI Conference on Durability of Concrete, 2000
This study points out the close relationship between several quality indicators of recycled aggregate and the performance of recycled aggregate concrete. Regarding the diversity in quality and composition of the recycled concrete products, three laboratory produced air-entrained-concretes with low, medium and high water-cement ratios and a non-air ...

Properties of recycled aggregate and recycled aggregate concrete: effect of parent concrete

Asian Journal of Civil Engineering, 2018
In the present investigation, an attempt was made to study the influence of the strength of parent concrete on the properties of recycled aggregates and recycled aggregate concrete. In this study, four grades of normal concrete mixes: M20, M25, M30, and M40 were considered as parent concrete to produce the recycled coarse aggregates and recycled ...
