Abstract

Penetration depth of inorganic waterproofing agent is difficult to assess quantitatively because inorganic waterproofing agent for concrete is not an internal waterproof membrane. However, evaluation of penetration depth of inorganic waterproofing agent is one of the most important evaluation index to secure efficiency in a consistent penetration. Therefore, this paper was proposed penetration depth measurement method of inorganic waterproofing agent for concrete and the penetration depth of the conventional inorganic waterproofing agent have been evaluated through the proposed penetration depth measurement method. As a result of test, the measured penetration depth throught the proposed penetration depth measurement method of inorganic waterproofing agent showed that more than 90% reliability.

콘크리트용 무기계 방수제는 내부 막을 형성하지 않기 때문에 무기계 방수제의 침투깊이 정량적으로 평가하기 어렵다. 그러나 무기계 방수제의 침투깊이 평가는 일관된 침투효율을 확보하는데 있어서 매우 중요한 평가지표 중 하나이다. 따라서 본 논문에서는 콘크리트용 무기계 방수제의 침투깊이 측정방법을 고안하였으며, 고안된 침투깊이 측정방법을 통하여 기존 무기계 방수제의 침투깊이를 평가하였다. 실험결과 고안된 무기계 방수제의 침투깊이 측정방법을 통하여 평가된 침투깊이는 90% 이상의 신뢰성이 있는 것으로 나타났다.
