Conventional clay bricks are heavier in weight which increase the overall dead load of the structure. Its formation creates smoke, loss of agricultural land and high energy consumption. To avoid these problems, Lightweight concrete is used in the construction due to its applications such as reduction of dead loads, seismic loads, environmental pollution and labor cost. In this study, the lightweight concrete is used to make lightweight concrete bricks/blocks. The lightweight materials used are; shale aggregate, expanded polystyrene and gypsum, paper pulp. The compressive strength and weight test of the samples were carried out. The papercrete was selected because of its lightweight, reasonable price and local availability. The results indicate that the papercrete bricks are 15% lighter in weight than conventional clay bricks. Due to low compressive strength these bricks are acceptable only for non-load bearing walls and are potentially ideal material for earthquake prone regions
