Carbon reinforced concrete (CRC) materials have proven to be excellent candidate materials for concrete-based nZEBs since they are characterized by a significantly lower CO 2 consumption during component production and much a longer lifecycle. The corresponding CRC technology has been successively implemented in …

Khalid et al. investigated the performance of plastic wastes in fibre-reinforced concrete beams [20, 31]. In their research, ring-shaped PET (Figure 5) was loaded into the concrete in order to improve its fracture energy, compressive strength, beam flexural strength, and splitting tensile. It also illustrated that the plastic fibres added to ...

reinforced polyester (GRP) pipes (GRP-WPs) for asphalt mixtures as a filler and Sánchez-Cotte et al. [21] present the implicational possibilities of using recycled concrete aggregate (recycled concrete aggregate of a building and recycled concrete aggregate from a pavement) as a replacement for natural aggregates in road construction.

The mix designs of all the concrete mixtures are given in Table 2. As previously men-tioned, the target for all the concretes was a mean compressive strength at 28 days of 30 MPa and a slump of 125 ± 25 mm. At the same water–cement ratio, RA concrete achieves, generally, a lower strength than NA concrete [2–4].
