Abstract

In order to clarify the effect of consolidant, the artificial porous material with low intensity was manufactured using granite powder and Portland cement. We have prepared four kinds of alkoxysilane system consolidants, a acrylic resin and a epoxy resin and investigated about characteristics before and after consolidation. As a result of the research, Silres BS OH 100 was effective for density and surface hardness. SS-101 with hydrophobicity and Site SX-RO with hydrophilicity had the good durability over salts weathering. On the other hand, Syton HT-50 and Paraloid B72 were easily destructed by salt weathering because they were concentrated on surface area by the low penetration depth. Araldite 2020 was the most effective consolidant for improvement of physical properties.

이 연구에서는 석조문화재 강화제의 처리 효과를 정량적으로 규명하기 위해 화강석분과 포틀랜드시멘트를 이용하여 강도가 낮은 인공 다공질 시료를 제작하고, 여기에 4종의 알콕시실란계 강화제와 아크릴수지, 에폭시수지 등 상업화 된 6종의 강화제를 적용하여 처리 전과 후의 특성을 비교 분석하였다. 실험 결과, Silres BS OH 100은 밀도 및 표면 경도 향상에 효과적이며, 발수성의 SS-101과 친수성의 Site SX-RO는 염풍화에 대해 향상된 내구성을 보였다. Araldite 2020은 물리적 기능 향상에 가장 효과적이나, Syton HT-50 및 Paraloid B72는 낮은 침투율로 인해 표면 일부에 처리효과가 집중되어 전체적으로는 풍화에 취약한 것으로 나타났다.
