碩士 === 國立海洋大學 === 河海工程學系 === 89 === The purpose of this study is to evaluate the effect of pozzolanic materials on mechanical properties, physical properties and durability of concrete. Fly ash and/or slag were used in the mixes to distinguish the various effects. Lab tests include compressive strength test, electrical resistance measurement, absorption test, gas penetration test, chloride diffusion test and corrosion test. Test results show that the compressive strength increases for fly ash and slag concretes , the optimum replacement is 20% fly ash +20%slag.In addition , the electrical resistance becomes higher , absorptivity becomes lower , and gas permeability coefficient becomes lower for fly ash and slag concretes. It appears fly ash and slag can densify concrete micro-structure and improve its durability.
