Flexural behavior of rubberized concrete interlocking masonry walls under out-of-plane load
Waste and industrial by-products, such as crumb rubber and fly ash, are being utilized as raw materials for making various masonry products. Rubberized concrete interlocking brick (RIB) is a newly developed product incorporated 10 crumb rubber, as a partial replacement for sand, and 56 fly ash, as a...

The compressive strength of the developed loadbearing RIB was 18.4 MPa. The results of flexural strength, moment�curvature relationship, displacement responses, joint opening, and failure modes for masonry walls made of the developed RIB under lateral load parallel to the dry bed joints are discussed.

The compressive strength of the developed loadbearing RIB was 18.4 MPa.
