The invention provides phosphogypsum concrete. The phosphogypsum concrete is prepared from the following raw materials (by weight): 7-9% of cement, 28-40% of limestone powder, 20-28% of stone, 9-27% of phosphogypsum, 8-10% of medium fine sand and 10-12.6% of water. By adding limestone powder and medium fine sand into the raw materials, smaller thickness specifications of concrete blocks or road bricks can be manufactured; and by adding phosphogypsum into the raw materials, density of a concrete product is enhanced so as to increase strength of a whole concrete block or road brick. Meanwhile, environmental pollution problem caused by stockpiling of phosphogypsum can be relieved, and resource utilization of phosphogypsum is promoted actively. The phosphogypsum concrete has good economic benefit and environmental protection benefit.
