| Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 92 === Often staying in the aggressive environment a hydraulic concrete structure should have abrasion erosion resistance. The abrasion resistibility of concrete surface will govern the durability of hydraulic structures. In this research two new developed waterborne sand and gravel flow abrasion test apparatus were adopted for test that simulates the abrasion erosion of concrete that takes place in the field.
The slag was added in concrete to improve the abrasion resistibility. Five water to binder ratios (w/cm) and four slag contents were selected for the mixture designs to make concrete specimens for abrasion test. Test results show that adding slag in concrete can obviously enhance its abrasion resistance. Concrete made with a w/cm ratio of 0.35, the abrasion erosion rate was the minimum for the 45% slag content namely, such a concrete has the best abrasion erosion resistibility.
