Bio-Board"s Surface Coating Processing Technology that Add Charcoal

&nbsp;&nbsp;Research result for charcoal processing surface coating material used gas concrete as material that intercept priority, because of high thermal conductivity of charcoal characteristic nature of charcoal itself. therefore intercept problem is drawn addition method of material have much, and add material that gap structure has consecutiveness and supplement shortcoming with research results.<BR>&nbsp;&nbsp;Therefore, this research investigated basis properties of matter of Bottom ash and foretell being nonpoisonous sex availability and choose match method.<BR>&nbsp;&nbsp;Also, being muck that add to Bottom ash, and controlled mixing rate (0%, 10%, 20%, 50%, 60%) of yellow soil. Styrofoam etc ... experiment each union ashes mixing ratio by 1:1, 1:2, 1:3 (yellow soil addition amount) and drew result.<BR>&nbsp;&nbsp;Change W/B to such result, yellow soil+bottom ash&quot;s surface coating material. and drew conclusion such as that apply from 10% to 30% and experiment the bottom ash addition amount.<BR>&nbsp;&nbsp;1. This research must secure enough workability by water - that union discretion required to give concrete fluidity Bottom Ash&quot;s the principal parts rate increases regardless of W/B gets into game that decrease, and deteriorates workability reducing concrete liquidity because also Bottom Ash&quot;s particle is bigger than sand relatively being done. compound material and water at concrete manufacture that use Bottom Ash - W/B&quot;s adjustment.<BR>&nbsp;&nbsp;2. Normal concrete that use general sand by low weight of Bottom Ash than general sand was expose that concrete that unit capacity weight is 2.488 and Bottom Ash&quot;s the principal parts rate is 100% is weight decrease effect about 43% by 1.764.<BR>&nbsp;&nbsp;3. Change of compressive strength and tensile strength by Bottom Ash&quot;s the cup aggregate s/a rate water - concrete that is s/a rate 100% about W/C 50% and general concrete that the s/a rate is 0% both 60% displayed marked compressive strength decrease by about 50% level, but showed good value to s/a rate 30%.<BR>&nbsp;&nbsp;Surface coating material that add yellow soil and Bottom ash on the basis of result of something wrong could know appropriateness to surface data of charcoal.
