| description | Lightweight concrete (LWC) is used in the construction of partition and panel walls in framed structures because it reduces the dead load acting on the structure. Rubberized lightweight aggregate concrete is made by using waste rubber tyre chips as a partial replacement of coarse aggregate which increases the ductility, and toughness and minimizes the impact effect of concrete. The presence of rubber content decreases the compressive strength and bond strength, which affects the durability of concrete. Nowadays, nanomaterials' application has received much attention to enhance concrete properties. Due to the nano-filler effect and the pozzolanic reaction, the microstructure becomes more homogeneous and less porous, especially at the interfacial transition zone (ITZ), which leads to reduced permeability. Among the nano-materials, nano-silica has gained particular attention compared to conventional mineral addition due to its better performance in concrete. Incorporating a small number of nanoparticles in concrete can modify the nano-structure of cementitious materials, thus producing high strength and durability. This study is to investigate the durability properties of rubberized LWC containing nano-silica at dosages of 1%, 3%, and 5% by replacement of cement, respectively. Durability under a marine environment is to be analysed based on compressive strength, bond strength, and resistance to the penetration of chloride ions for 28 and 56 days. |
