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.

In this study, to improve the required properties of tile cement mortar such as excellent water retention capacity (WRC), workability, open time, sag resistance, and tile adhesive strength, tile cement mortars containing the several additives with different ratio were compared and analyzed. By adding small amount of synthesized starch to hydroxypropyl methylcellulose (HPMC) which is used for improving WRC, the decrease of moisture evacuation from mortar surface was observed and the workability of mortar was improved with long open time. Polyacrylamide (PAAm) and ethylencvinyl acetate (EVAc) were also added in order to increase the adhesion of tile. As a results, the saggings of mortar itself and tile were decreased and the adhesive strength of mortar between base and tile was enhanced. By adding melment, the workability was improved by increasing the fluidity of mortar. It is postulated that the properties of tile cement mortar was improved by adding 0.80~1.20% of HPMC, 0.10~0.15% of starch, 0.001~0.015% of PAAm, 0.05~0.10% of EVAc and 0.003~0.005% of melment to the cement mortar.

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.

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.

Today, the conception of building architecture is changing the conception that it is a kind of product and the operator of construction try to produce excellent building through developing efficiency and materials of building component. This study improves the problematic point of the extenor tile setting, through making on experiment on the method of it and purposes doing to do the exterior tile setting of good quality as it selects out of the most conformable the method. The experimental materials choose the tile of 60$\times$108mm size which are using frequently in the exterior tile setting and mortar is made from sand of Han river and potland cement, which apply the volume mixing of the ratio 1：3. The water cement ratio (W/C)is made up 62％ The methods of tile setting utilise the method of the tile setting and laying the method of the tile improved setting and laying, the method ol the pressing adhesion, the method of the improved pressing adhesion and the method of setting adherent (the method of VIBRATOR).

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.

This study aims to find out the reason that tile adhesive(type III) for ceramic tile does not harden under some conditions especially high humidity even though long curing time. Bonding strength of adhesive between substrate and ceramic tile is evaluated depending on bonding conditions such as substrate kind(concrete, board), bonding material (tile adhesive, tile cement) and curing condition(humidity 50, 70%). Based on the results, this study aimed to establish the quality of tile adhesion strength under the relevant conditions.

This paper is to present the performance data for pressure setting method using some tile bonds for application on the Ondol-Heating floor system. For this purpose, powder and liquid tile bonds(Organic.Inorganic mixed tile bonds) were compared with the conventional tile cement for pressure setting method in the sight of the adhesive stability of porcelain tile. It tested for tiles after 14, 28days under standard condition and severe conditions. The severe conditions were water immersion and heat ageing($70^{\circ}C$). Another experimental factors concerned tile bond properties such as mixing ratio(in case of using liquid admixture), open time, which are supposed to affect the tensile strength of tile, were studied and discussed through the experiments.

Currently, polymer-based tile cement (Thin-bed method) and epoxy adhesive (Thick-bed method) are mainly used as tile adhesive for polishing and porcelain. In the case of epoxy adhesive, there is a low economic efficiency, there is a problem that the work efficiency is reduced by mixing the resin and the hardener. In particular, the epoxy contains a bisphenol A and amine component, there is a risk of workable disease when a worker is exposed to odor and harmful gases generated in the epoxy adhesive for a long time. Against this background, it is necessary to analyze the hazards of using epoxy adhesives indoors, and develop cementitious high performance tile adhesive products with significantly lower hazards than epoxy adhesives.

The production of Portland cement involves maximum use of resources and energy, which leads to destruction of tile ecological environment, raising in serious environmental issues such as acid rain and the greenhouse effect. In order to combat the arising problems associated with Portland cement, it thus is necessary that a non-clinker cement should be developed. In this study, non-clinker cement is produced by blending granulate blast furnace slag with phosphogypsum as main materials, and small amounts of hydrate lime or waste lime as activators. This paper aims to investigate compressive strength according to various condition of mixing ratio, blame, W/C ratio and curing temperature. Compressive strength of non-clinker cement increases continuously according to increase in curing age and blain. Although the compressive strength is fairly comparable to that of OPC in the early curing age, it reaches a higher lever in the later age than that of OPC due to the optimum mixing ratio and the continuous reaction of slag and phosphogypsum. Results obtained from this study have shown that non-clinker cement could be used as a replacement of OPC.
