Abstract：Dry-hard recycled concrete is a type of rapid hardening green materials with early strength,and it accords with development needs of construction industry modernization. According to pressure forming requirements of test block,a type of dry-hard concrete test block sleeve pressure forming device was designed based on plastic mould. The preparation of dry recycled con-crete with 100% recycled coarse aggregate replacement percentage was carried by this device. Results indicate that:the strength of dry-hard recycled concrete first increases and then decreases with the increasing of molding pressure. When the water temperature is (25士3)℃,water curing is better than standard curing and it can improve the compressive strength of dry recycled concrete by about 20%.
