Mar 25, 2015  Typically available lightweight aggregates are usually produced using sintered fly ash, expanded clay and expanded shale [2,3,5,6,7]. They inherently have a large number of pores, which results in lower strength, stiffness and greater deformability [2,6]. Thus, weak lightweight aggregates affect the strength and failure of concrete .

Construction of Concrete Canoe using Light Weight

light weight concrete is achieved by using aggregates such as expanded clay, perlite, vermiculite, EPS beads etc[3,4,5]. The usage of light weight aggregates has drastically reduced the overall mass of concrete when compared to nominal concrete. However, attaining the characteristic strength of nominal concrete was indeed a challenge.
