Multi-recycling of polypropylene fibre reinforced concrete: Influence of recycled aggregate properties on new concrete
نویسندگان
چکیده
• Recycling of polypropylene fibre reinforced concrete was investigated. Three generations recycled aggregate were produced, tested and recycled. The content fibres recovered by recycling embedded in quantified. Results show the benefits using new concrete. Herein, an investigation multi-generational recyclability (PPFRC) performed. parent concretes produced with 0 6 kg/m 3 fibres. After recycling, obtained coarse aggregates (RCAs) used fibres, repeating for three always same quantities Properties RCA, mechanical properties concrete, recovery rate within RCA measured. results study that PPFRC offers significant to production. This is achieved through reintroduced into as well aggregates, leading increased residual tensile strength.

Performance of Continuously Reinforced Concrete Pavement Containing Recycled Concrete Aggregate
In 1995, the Texas Department of Transportation (TxDOT) began reconstruction in Houston on a section of IH-10 with continuously reinforced concrete pavement (CRCP). The unique aspect of this project was the use of crushed concrete as both coarse and fine aggregates in the new concrete. No virgin aggregates were used. The primary objectives of this study were to evaluate (1) the material propert...

In order to study the basic mechanical properties of basalt fiber reinforced recycled aggregate concrete, the concrete mix ratio, the length and the volume mixing ratio of chopped basalt fiber yarn are designed for changing factors. A total of 324 specimens have been completed for this investigation. The compressive strength, splitting tensile strength, elastic modulus and axial compressive str...
متن کاملAssessing relationships among properties of demolished concrete, recycled aggregate and recycled aggregate concrete using regression analysis.
Recycled demolished concrete (DC) as recycled aggregate (RA) and recycled aggregate concrete (RAC) is generally suitable for most construction applications. Low-grade applications, including sub-base and roadwork, have been implemented in many countries; however, higher-grade activities are rarely considered. This paper examines relationships among DC characteristics, properties of their RA and...
متن کاملApplications and Properties of Fibre Reinforced Concrete
In conventional concrete, micro-cracks develop before structure is loaded because of drying shrinkage and other causes of volume change. When the structure is loaded, the micro cracks open up and propagate because of development of such micro-cracks, results in inelastic deformation in concrete. Fibre reinforced concrete (FRC) is cementing concrete reinforced mixture with more or less randomly ...

This research is concerned with the mechanical and physical properties of hemp fibre reinforced concrete (HFRC). An experimental program was developed based on the statistical method of fractional factors design. The variables for the experimental study were: 1) mixing method; 2) fibre content by weight; 3) aggregate size; and 4) fibre length. Their effects on the compressive and flexural perfo...
