The purpose of this study is to develop eco-friendly finishing materials of acrylic emulsion-modified mortars using lightweight aggregate carrier which contains pyroligneous liquid. Four types of light-weight aggregate carriers such as perlite, vermiculite, charcoal and zeolite are selected. The acrylic emulsion-modified mortars are prepared with light-weight carrier replacements to dolomite of 0, 5, 10, 15, 20%, and tested for flowability, adhesion in tension, water absorption coefficient and antibiosis. As a result, the flowability of acrylic emulsion-modified mortars using zeolite light-weight is improved with increasing light-weight carrier content. The adhesion in tension of acrylic emulsion-modified mortars using lightweight carrier is satisfied with KS requirement. Especially, the adhesion in tension of acrylic emulsion-modified mortars using light-weight aggregate carrier at a high temperature of 40oC are better than the low temperatures of 0oC and 20oC. The water absorption coefficient of acrylic emulsion-modified mortars using light-weight aggregate carriers is increased with increasing light-weight carrier content. However, the water absorption coefficient is satisfied with KS requirement. The antibiosis of acrylic emulsion-modified mortars using zeolite light-weight carrier is remarkably improved with increasing light-weight carrier content.

The development of functional finishes for the improvement of indoor air quality is one of important issues in the fieldof building materials. Indoor air quality can be affected by gases, particulates, microbial contaminants or any mass thatcan induce adverse health conditions. The purpose of this study is to develop eco-friendly internal material of acrylicemulsion mortars using light-weight aggregate carrier which contains pyroligneous liquid. Four types of light-weightaggregates (perlite, vermiculite, charcoal and zeolite) those are functionally used in interior finishing materials are selectedand the properties such as flowability, adhesion, water absorption coefficient, crack and impact resistance are evaluatedin accordance with KS F 4715. As a result, the properties of acrylic emulsion mortars using light-weight carrier in thisstudy are satisfied with KS requirements. Among the four types of mortars with light-weight carrier, properties of acrylicemulsion mortars using zeolite carrier is more excellent than those of other light-weight carriers.

This study was carried out to obtain the optimal ammonia removal efficiency using pyroligenous liquid for the economical and environment-friendly odor removal at a petty livestock farmhouse. The ammonia removal efficiencies were evaluated due to changing dilution rates(×10, ×20, ×30, ×50 and ×100 times) and different spray amounts(10㎖ and 20㎖) of pyroligenous liquid. The wet scrubber device was used to remove odor in closed-type livestock farmhouse. According to dilution rate of the pyroligenous liquid, the optimum rate was 20 times and the removal efficiency increased by decreasing dilution rates. In the case of spray amounts with the optimum dilution, the amount was 20 ㎖ and the removal efficiency increased by increasing spray amount. Also, the removal efficiency by using wet deodorizing device was 83.0～97.0% with 20 times diluted liquid.
