Shear behaviour and mechanical properties of steel fibre-reinforced cement-based and geopolymer oil palm shell lightweight aggregate concrete

The shear behaviour and mechanical properties (compressive, splitting tensile and flexural strengths) as well as the flexural toughness of steel fibre-reinforced cement-based and geopolymer oil palm shell lightweight aggregate concrete (OPS LWAC) were experimentally investigated in this paper.
