Thermal Performance of Concrete with Recycled Aggregates from CDW Plants

Performance of High-strength Concrete Made with Recycled Ceramic Aggregates

Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...

Low Cycle Fatigue Behavior of Concrete with Recycled Concrete Aggregates

A comparison of concrete containing recycled concrete coarse aggregates and natural coarse aggregates subjected to high strain, low cycle compressive fatigue is presented. Using a strain based feedback control loop, concrete cylinders are compressed at 15µε/s to a specified strain then unloaded to zero stress for 10 cycles. After cycling, all samples are loaded to a strain of 0.008. Direct conc...

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

Life Cycle Assessment of Sustainable Concrete Made With Recycled Aggregates

The results of an environmental study on concrete manufacture that follows the standard protocol of life cycle assessment are shown in this document. The study has been done for seven types of concrete: one conventional and six containing cement kiln dust (10%), marble sludge (10%) and demolition waste (10%, 80% and 100%) respectively, in partial or total substitution of natural aggregate. Six ...

Thermal properties of concrete with various aggregates

Concrete is the most common building material with a high thermal mass, and it is of interest to study how thermal mass of buildings influences such factors as their peak power consumption and their thermal comfort. We have studied whether it is possible to improve the thermal properties of concrete for buildings with high thermal mass by using aggregates with high heat capacity and/or material...
