24-hour Fire Produced Effect on Reinforced Recycled Aggregates Concrete Beams

High Performance Reinforced Concrete Beams made with Sandstone Reactive Aggregates

An investigation on the flexural behaviour of reinforced high performance concrete (HPC) has been conducted. Crushed sandstone known as reactive aggregate was used for both fine and coarse aggregates. In addition, mineral admixtures such as silica fume and fly ash combined with superplasticiser was used. The beams were made with concrete having compressive strength in the range of 74 88 N/mm 2 ...

Finite Element Modeling of Reinforced Concrete Beams Exposed to Fire

Abstract: The practical implementation of performance-based fire safety design of reinforced concrete (RC) structures hinges on the availability of accurate numerical simulation tools for the behavior of RC members exposed to fire. This paper presents a three-dimensional (3D) finite element (FE) model for the accurate prediction of both the thermal and the mechanical behavior of RC beams expose...

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

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...
