Evaluating the time lag and decrement factor of mortar and concrete containing OPBC as an agricultural by-product lightweight aggregate

Replace the normal weight aggregate with wastes or by-products materials is an appropriate method for producing a sustainable cement-based material. The replacement helps to have an energy-efficient component that reduces environmental impact. Time lag and decrement factors are vital wall system var...
