Strength Properties of Hardened Concrete Produced with Natural Aggregates for Different Water/Cement Ratios

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...

Investigating properties of fresh and hardened self-compacting concrete made of recycled aggregates

Self-compacting concrete is a new high performance concrete with high ductility and segregation resistance. In recent years, construction material manufacturers have focused their attention on lightweight concrete and have strived to use lightweight concrete, if possible, in load-bearing parts of buildings. Concrete with both self-compacting and lightweight properties is favourable in this cont...

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...

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

Effect of Different Moisture States of Surface-Treated Recycled Concrete Aggregate on Properties of Fresh and Hardened Concrete

This study examined the properties of fresh and hardened concretes as influenced by the moisture state of the coarse recycled concrete aggregates (RCA) after surface treatment. Surface treatment was performed by immersing the coarse RCA in a calcium metasilicate (CM) solution. The treated coarse RCA was maintained in three controlled moisture states, namely, air-dried, oven-dried, and saturated...
