Abstract: The growth and the actual configuration of our cities has led to diminish the presence of green areas. This has led to a growing interest in the development of novel solutions that can help to increase the presence of green areas and to provide better living environments in our cities. During the last years our research group has been working in the development of a new concept of green façade that considers the use of a novel material with enhanced bioreceptivity [1], by using low-pH magnesium-phosphate cements (MPC). The enhanced bioreceptivity of MPC and carbonated OPC mortars was evaluated under laboratory conditions showing the larger bioreceptivity and colonisation by algae in the MPC mortars [2]. Nevertheless, natural colonisation experiments did not allow to obtain a visible biological growth and similar colonisation of MPC and OPC samples by bacteria and fungi [3]. This work presents some preliminary results in the up-scaling and industrial validation of the mortars referenced above. This work has considered the optimisation of the dosages to be used under the industrial environment of a precast concrete factory. We discuss the use of super adsorbent polymers (SAP) to increase the water availability for biological growth. on different Furthermore, preliminary results are given on the effectiveness of different strategies to promote biological colonisation on this materials by using different pre-inoculation alternatives.
