Defects such as falling and cracking of tiles installed in the bathrooms of apartment houses are frequently occurring. Therefore, in order to solve this problem, the A/S cost of construction companies and consumer complaints are increasing. The causes of tile defects include problems such as the selection of tile adhesive and lack of adhesive strength, the carelessness of the installer, the base surface, and the absorption rate of the tile. Therefore, in this study, an adhesive construction method using tile adhesives with high resistance to deformation of floors and tiles was studied. In addition, the properties and construction methods of tile adhesives were evaluated.

The aim of the research is providing a fundamental data on quality and constructability of direct tile setting method depending on various cement to sand ratio for tiling dry cement mortar. A large number of tile setting failures reported is related with the cement mortar and its construction for tiling. Because of different materials of tiles, the properties of tiling dry cement mortar, an adhesive for tiling, can influence on quality and constructability of tiling differently. Practically, the easiest way of controlling the properties of the tiling dry cement mortar is to control the proportion of cement and sand. Hence, in this research, sand to cement ratio (S/C) was controlled. Since there is no standarized method on evaluating performance of dry cement mortar for tiling, a several sensory evaluation methods were suggested and executed. According to the experiments conducted in this research, the adhesive performance of cement mortar for tiles can be different depending on the sides such as tile and substrate. Additionally, depending on S/C, finishability, initial adhesive performance, and tile shifting resistance can be changed for ceramic tile. Therefore, under the conditions of this research, about 5 of S/C can be recommended for appropriate performace of tiling dry cement mortar.

Polishing tiles among porcelain tiles are more durable and aesthetic than ceramic tiles, so their demand has recently increased. In particular, since polishing tiles have a very low absorption rate, organic adhesives with chemical bonds are mainly used. However, organic adhesives have low economic efficiency and some volatile organic compounds (TVOCs). Therefore purpose of this study was to evaluate the performance of polishing tile adhesion by developing organic-inorganic adhesives, which have chemical bonds and mechanical bonds. As a result, since the amorphous chain and chemical bonds of the polymer in the tile adhesives, both tensile and shear adhesion strength were satisfied with the KS L 1592, KS L 1593, and the rate of length change itself in the thermal cycling was lower than organic adhesives. So it is thought that it is possible to replace some organic adhesives.

The studies on the rural housing have focused on folk housing, but this study focuses on the contemporary rural housing with special reference to the roof types/materials and the outer wall materials. The research area of this study is the fourteen rural settlements in Jeju Island. The hip roof type, the hip/flat roof type, the simple-flat roof type, the gable roof type, and the eyebrow-and-flat roof type are the most frequent roof types. Among the roof materials, the precoated steel plate, the artificial slate, the cement, the cement/roof tile, and the cement/artificial slate are the most frequent materials. The cement holds more than a half of the outer wall materials, and the cement/basalt rock, the tile/cement, the tile, and the diverse siding are the next frequent outer wall materials. The comparison of the rural housing reveals that there are some clear differences between Jeju Island and Gyeongnam Province in terms of the roof types and the outer wall materials.

In this study, we prepared three kinds of substrate for the adhesion strength test of cementitious tile adhesive. As a result, the maximum adhesion strength is obtained from the concrete substrate specified in ISO 13007 regardless of curing condition of tile cement specimens.

This study dealt with an experimental study on development of tile grout cement complied with international standards criteria. Tile Grout Cement is divided two grade, 1 type and 2 type, in KS F 1592:2011. International Standards(ISO) is divided 9 grade. performance evaluation for cement content was measured according to KS L ISO 13007. water absorption test results are based on the cement content 30% were satisfied with International Standards criteria. strength test results are based on the cement content 25% were satisfied with International Standards criteria.

시멘트 업계에서 필연적으로 다량 배출되는 질소산화물(NOx)의 법적 규제치는 350ppm(산소 농도 13% 기준)이나 대부분의 시멘트 사업장에서 기준치를 초과하여 배출되고 있는 실정이다. 시멘트 산업은 석회소성로의 고온운전과 다량의 연료사용 등 시멘트 제조의 공정특성상 타 산업에 비해 많은 질소산화물을 배출하여 왔으나, 사업장 주변지역 환경에 질소산화물이 미치는 영향에 관한 연구가 전혀 이루어지지 않아 이에 대한 자료가 전무한 실정에 있다. (중략)

Selecting a proper tile cement for ceramic tile is important to secure tile construction quality. But there is some ambiguity in standards about evaluating adhesion test such as using KS L 1593 in Lab test but using KS L 1592 in site. So, this study aims to how to select proper tile cement for securing adhesion strength in site considering both tensile and shear adhesion strength of cement for ceramic tile. Also, when doing tensile adhesion test in site, there may be adhesion drop because of cutting tile with grinder. As a result, drop of adhesion strength is about 9% ans quality manager consider these factor and should select proper tile cement.
