In this article, the effectiveness of the bioconsolidation technique applied to degraded structural materials is illustrated as a new method of consolidation and conservation of the existing building heritage in a less invasive way. Satisfactory results have been obtained by an experimental campaign carried out through non-destructive diagnostic tests, static destructive mechanical tests, and microstructural analyses on a series of natural stone material specimens and artificial stone materials before and after the use of bioconsolidants. The consolidated specimens have been tested after three to four weeks after the application of the M3P nutritional solution on each specimen. The effect on the microstructure of this technique has also been observed using scanning electron microscope and optical photomicrograph, the formation of new calcium carbonate crystals promoting the structural consolidation of the materials under examination was observed in all the specimens analyzed.
在本文中，生物固结技术应用于退化结构材料的有效性被阐释为一种以较低侵入性方式对现有建筑遗产进行固结和保护的新方法。通过对一系列天然石材材料标本和人造石材材料在使用生物固结剂前后进行无损诊断测试、静态破坏性力学测试和微观结构分析的实验活动，已取得了令人满意的结果。在对每个标本施用M3P营养液三到四周后，对固结后的标本进行了测试。还使用扫描电子显微镜和光学显微镜观察了该技术对微观结构的影响，在所有分析的标本中均观察到新碳酸钙晶体的形成促进了所检测材料的结构固结。
