The strength and durability of precast concrete under different curing conditions were studied from the actual production of precast reinforced concrete member. The results showed that the early strength of concrete at room temperature for 24h, standard steaming for 12h and constant temperature steaming for 12h could all meet the concrete form removal requirements, but the concrete strength by constant temperature steaming for 7d, 28h was lower than room temperature curing and standard steaming. The durability of concrete in steam curing was lower than that in room temperature.
