Abstract: Background: Durability and strength are two inseparable indices of concrete and mostly in areas where the concrete is being subjected to severe exposure conditions. Bayelsa state alongside most states in the Niger Delta Region of Nigeria, in searching for a stable foundation for buildings, locate their footings at submerged levels below natural ground water table. The effect of continuous immersion of concrete on weight loss and strength for varying brands of Nigerian....

Abstract: Pervious concrete is an eco-friendly construction material that helps in reducing urban flooding and protecting groundwater by allowing water to flow through its porous structure. This research investigates how different sizes of coarse aggregate affect the workability and strength of pervious concrete with focus on refining its mix design for practical use in city. The study examines the relationship between aggregate size and workability parameters such as slump and compacting factor and also compressive and flexural strength and permeability. The research methodology involves creation of concrete samples with different aggregate sizes and then testing their workability, strength and permeability.....
