| Abstract |
The purpose of this study is to evaluate the properties of eco-friendly cementitious surface preparation materials using light-weight aggregate carrier which contains pyroligneous liquid. Four types of light-weight aggregates such as perlite, vermiculite, charcoal and zeolite are selected as a light-weight carrier containing pyroligneous liquid. The cementitious surface preparation materials using acrylic emulsion with light-weight aggregate carrier are prepared with various light-weight carrier replacements to silica sand and tested for flowability, adhesion in tension, water absorption coefficient, resistance about repeating warmth and coldness, crack and impact resistance, antibiosis. And the properties are evaluated in accordance with KS F 4716 and JIS Z 2801. As a result, the performance of cementitious surface preparation materials using acrylic emulsion with light-weight aggregate carrier are satisfied with KS requirements. Also, among the 4 types of light-weight aggregate carrier, the properties of the cementitious surface preparation materials using a zeolite carrier is more remarkable than those of other light-weight carriers. The cementitious surface preparation materials using zeolite light-weight carrier have a outstanding antibiosis over 99% at a light-weight carrier replacement of 20% for silica sand. |
