The Role of Geometry on a Self-Sustaining Bio-Receptive Concrete Panel for Facade Application

Bio-receptivity refers to the aptitude of a material allow for natural growth small plant species on stony surfaces with minimum external influence. Despite numerous associated environmental benefits, mosses and lichens facades has always been viewed as negative phenomenon due random shabby conditions. This research dealt design self-sustaining bio-receptive concrete facade system an aim create more sustainable green construction industry. The used surface geometry variable facilitate moss panels in ordered systematic manner. exercise was attempt not only address functional aspect bio-receptivity but also its aesthetical quality, which primary influence people’s perception can promote mass use this type material. conducted top-down approach, where first, through by research, six distinctly designed were fabricated using adapted composition (blast furnace cement 75% slag, 0.6 water/cement, sand 0–4 mm gravel 5–8 mm) boundary condition. mixture together no curing policy resulted highly porous panels, suitable properties. Next validation phase, geometry/roughness water retention ability subsequent evaluated vitro experiments. experiment based quantitative measurements weight, relative humidity temperature at several time intervals. moss-growing carried out within ideal greenhouse condition initially inoculated spores; results qualitative observation period 4 months. According comparative analysis these results, same composition, Panel 2 showed highest bio-colonization owing prominent geometry, whereas 5 least plain despite high absorption capacity. Thus, role extensively proven outcome set general guidelines have formulated panel, bio-receptivity.
