According to proof test , the error is lower than 2 mpa when producing middle , low grade recycled concrete with another recycled aggregate 通过验证试验,得出使用不同的再生骨料配制中低强度再生混凝土时偏差在2mpa以内。
A Proof test is a form of stress test to demonstrate the fitness of a load-bearing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items.
