Recycled Concrete - an overview ScienceDirect Topics

Recycled concrete was produced by six different contaminated construction materials. Coir fiber was added to stabilize the heavy metals in the concrete. The coir fiber was treated with 2% NaOH so that various pores were generated on its service, which largely increased the combination between coir

Concrete Design - an overview ScienceDirect Topics

This chapter briefly describes the state-of-the-art of concrete design involving recycled aggregate and reviews present knowledge of the interfacial transition zone (ITZ) and recycled concrete modelling. A meso-scale, two-dimensional model is proposed to simulate stress distribution in the (natural, glazed and unglazed ceramic) aggregate/ITZ/cement matrix system when exposed to uniform external pressure.

Control Concrete - an overview ScienceDirect Topics

The recycled concrete with 100% carbonated RCA replacement percentage performs poorly because of excess water in the mixture. The 30-0-0 and 100-0-0 mixes achieve a middle-tier tensile strength result of about 3.43 and 2.96 MPa, respectively. The concrete made with 30% carbonated RCA replacement percentage realized an increased tensile strength performance when compared with the concrete with

Rebuilding with Recycled Concrete - ASME

2021-3-24  Now, after five years of weather and use, the recycled concrete has proven that it can perform as well as new concrete and often better. Not only that, but the recycled concrete can be recycled again and used a second and third time without its target strength being compromised, although the rate of strength gain is less with each use.

Rebuilding with Recycled Concrete - ASME

2021-3-24  In a paper published in Construction and Building Materials, Alam showed that recycled concrete could be as durable and strong as fresh concrete, and sometimes stronger. After five years of weather and use, the recycled concrete has proven that it can perform as well as new concrete. Image: UBC. The recycling process for concrete is simple enough.

Environmental perspectives of recycled concrete

2021-2-8  In this study, we assessed the environmental perspectives of recycled concrete powder (RCP) as a cement replacement, which is produced as a by-product in the concrete recycling process. First, the reference mixture was prepared and new mixtures were designed with replacement ratios 10, 20, 30, 40 and 50 % of RCP.
