·Pervious concrete has made a comeback as a green infrastructure solution for urban areas The fast adoption of the permeable pavement practice by many cities worldwide warrants an urgent response from researchers to address the lack of standards for mixture optimization pavement design and characterization methods which results in field placements
Recycled concrete powders RCPs are the main by product produced in the process of preparing recycled aggregate from construction and demolition waste CDW This paper reviews the reutilization of RCPs in detail and divides the review into three parts properties activity excitation and applications The physical and chemical properties of RCPs and their production methods
·The STR are incorporated into concrete and prepared as STR concrete STRC using a coarse and fine aggregate shell production process By optimizing the mixing method of STR slurry we obtained the best mixing process and studied the influence of STR dosage and water binder ratio w / b on the compressive strength of STRC
·Concrete is a durable building material made by combining aggregates binders and water The water reacts with the binder in a chemical process creating a solid cohesive structure
·Concrete workability decreased with an increase in WC along with producing low amount of CO 2 with high compressive strength Rashid et al 2017 Elçi 2016 investigated the use of crushed ceramic wall tile and crushed floor tile in concrete FA and CA were replaced by crushed ceramic tile up to 100%
·Geopolymer concrete s mass change was determined using thermogravimetric analysis and differential thermogravimetry Reutilization of granite waste in the preparation of fly ash based geopolymer concrete provides solution for issues related to waste management and improved several geopolymer concrete s properties
·Fresh and hardened concrete qualities were tested and the concrete replacement value for coarse aggregate was optimised at 40% partial replacement of natural coarse aggregate by PP plastic in
·The fresh concrete was cast in molds with dimensions of 40 × 40 × 160 mm to determine its mechanical properties including its elastic modulus and compressive strength according to the Chinese standard [23] After being stored in a standard curing room for 28 days the specimens were tested on a 100 kN electronic universal testing machine to
