Description
Summary:The pressing need for innovative green solutions in urban environments is evident. This study explores a novel concept of integrating green areas directly onto structural surfaces as a means to enhance urban infrastructure with real floral life. Specifically, the research focuses on the potential application of a newly developed bioreceptive concrete that promotes the growth of microorganisms on its surface. The concrete properties were carefully optimized to enhance bioreceptivity by altering the mix design and employing a different type of hydraulic binder to meet the conditions necessary for biological growth. This bioreceptive concrete was tested as an additional layer on top of normal OPC concrete which was used to manufacture to the supporting structure. The study primarily examines two key properties of the bioreceptive concrete: pH and porosity. The pressing need for innovative green solutions in urban environments is evident. This study explores a novel concept of integrating green areas directly onto structural surfaces to enhance urban infrastructure with real floral life. Specifically, the research focuses on the application of newly developed bioreceptive concrete, which is engineered to promote the growth of microorganisms, including mosses, lichens, and algae, on its surface. To achieve optimal bioreceptivity, the concrete's properties were carefully modified by changing the mix design and using Magnesium Phosphate Cement instead of traditional Ordinary Portland Cement. This substitution resulted in a significant reduction in pH, creating a more favorable environment for the life of plants and microorganisms. Additionally, an optimal formulation was developed with a suitable grain size distribution to achieve the desired porosity, which is critical for water retention and microbial establishment. This bioreceptive concrete was tested as an additional layer on top of normal OPC concrete which was used to manufacture to the supporting structure. The concrete properties were carefully optimized to enhance bioreceptivity by altering the mix design and employing a different type of hydraulic binder to meet the conditions necessary for biological growth. The study primarily examines two key properties of bioreceptive concrete: pH and porosity.
