기능성 방청혼화제 혼입율 변화에 따른 모르타르의 방청성능 평가

In this study, fundamental properties of mortar with the variation of dosage of anti-rust agent has been tested to evaluate the effect of the anti-rust agent. Dosage of anti-rust agent was fixed as 0,3,6,9%, respectively. The variation of the flow, compressive strength and diffusion speed of chloride ion has been tested to evaluate the effect of the anti-rust agent. Results showed that flow has been smally increased. For the compressive strength, compressive strength increased with the increase of dosage of agent. For the diffusion speed of chloride, the speed decreased with the increase of dosage of the anti-rust agent. For the overall consideration, it could be identified that when the dosage of anti-rust agent was fixed as 3-6%, the mortar showed the optimum performances.
