Civil engineering materials experiment is the important link to master knowledge of civil engineering materials. Taking cement concrete anti-permeability test for example, optimizing and innovating the traditional cement concrete anti-permeability instrument and the test itself, creatively puts forward the development thinking, technical route and experiment mechanism of new cement concrete anti-permeability instrument. Analysis shows that new cement concrete anti-permeability instrument and its test, under the premise of keeping anti-permeability instrument test mechanism unchanged, creatively proposes appropriate increase of concrete specimen size, pre-embedded press-leading tube internally, etc key measures, avoiding seal procedure of the existing anti-permeability instrument cleverly. Moreover, the subsequent comparative tests and theoretical analysis are worth looking forward to. And technical route will be also prudently carried forward. Test and development scheme cover innovation characteristics obviously. Research achievement provides important references for civil engineering materials experiment and innovation,as well as other civil engineering courses, and provides lessons for civil engineering materials teaching and other courses teaching. Simultaneously, the achievement promotes amendment and improvement in traditional codes, bringing social benefit and economic value for concrete in civil engineering anti-permeability structure.
