Innovation of lightweight concrete slab / Wan Nursafiizzati Wan Abd Manan

A traditional slab has several negative effects on the economy, environment, and worker productivity. Therefore, it is intended for the lightweight concrete slab to replace the conventional one in the construction industry. According to previous studies, the removal of non-structural concrete from the center of the slab allows for the creation of a lightweight concrete slab using coconut shells. In order to assess the usability of the lightweight concrete slab, tests for flexural strength and compressive strength were conducted. It turned out that after 17.6 % concrete reduction, the results of the testing showed that the lightweight specimen had superior readings to the standard specimen. Since the demand for lightweight concrete components is expected to increase and reach its peak in 2028, this lightweight concrete innovation also aims to replace the conventional concrete slabs. It can also do this by cutting manufacturing costs because, while raw material costs are rising, the lightweight slab uses less concrete compared to normal concrete.
