본 연구에서는 찹쌀풀, 전분풀, 해초풀의 농도에 따른 재료특성이 전통벽체의 마감층에 미치는 영향을 조사하였다. 찹쌀풀과 전분풀은 해초풀에 비해 점도가 낮기 때문에 곡물풀을 포함하는 모르타르는 상대적으로 높은 유동성을 가지며, 모든 농도에서 균열이 발생하지 않았다. 반면, 해초풀이 혼입된 모르타르는 해초풀의 높은 점성으로 인해 균열에 취약했다. 그러나, 균열 발생 위험성에도 불구하고 해초풀 사용시 곡말풀 보다 월등한 압축강도를 나타냈다. |

According to the current specifications of repair for heritage buildings, the sand coat wall should be plastered using organic additives.
However, the concentration of these additives that influence the finish and quality of the wall was not specified. The understanding of wall
finishing materials is currently low regarding concentration properties and has been too dependent on the experience and the sense of workers
in this field. In this study, the influence of material properties of three organic additives such as sticky rice, starch, and seaweed pastes on
the finishing layer of traditional walls were investigated. The viscosity of nine paste samples with various concentrations of 4.4%, 8.5%,
12.2% for sticky rice and starch pastes of 4.4%, 8.5%, and 10.3% for seaweed grass were measured. Experiments for mortar samples with
these pastes were performed involving workability, surface finishing observation, weight change rate, compressive strength, and
thermogravimetric analysis. As a result of this experiment, the mortar samples with grain paste such as sticky rice or starch paste had
relatively high workability and cracks did not occur at all concentrations since the paste had a lower viscosity than seaweed paste. On the
other hand, in the mortar sample with seaweed paste, cracks occurred in all samples except for the 4.4% sample due to the paste’s high
viscosity. Based on these obtained results, the risk of cracking was higher when using seaweed paste than sticky rice or starch paste at the
same concentration. However, despite the high risk of cracking, the samples containing seaweed showed outstanding strength compared to
other samples made evident in the combined effects of the filling of the viscous film in the seaweed paste and the carbonation acceleration.
The results of this study are valuable as evidence for determining the appropriate concentration of traditional organic additives when
developing or revising specifications. |
