Evaluation for pressure-feeding property of concrete
专利汇可以提供Evaluation for pressure-feeding property of concrete专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a sample in the same state as that in the actual feed under pressure, by performing a test such as slump test with a pressure tester comprising a cylinder member and a piston member. CONSTITUTION:A lid body 13 of a cylinder member 1 with a piston member 2 retracted is removed to fill it with a sample K from the free end 12 thereof. Then, after the free end 12 of the cylinder member 1 is closed with the lid body 13, the sample K is pressurized with the piston member 2 using an hydraulic jack or the like at a driving section 3 based on a pressurizing program. After the pressurization as specified, the lid body 13 is removed and the sample K is extruded with the piston member 2 to take out the sample K following the pressurization. Finally, a slump test and a strength test is conducted using the sample K withdrawn and the results are compared with the required nature of concrete.，下面是Evaluation for pressure-feeding property of concrete专利的具体信息内容。
