Compressive strength analysis of mortars with partial replacement of aggregate by Crushed Porcine Bone (CPB)

The field of construction is directly associated with environmental pollution due to the processes and materials used, including cement, which is the main component of mortar. Therefore, it is particularly important to find new construction materials that in addition to meeting the current regulatory requirements, contribute to sustainable development and circular economy. Based on this, the present research aims to analyze the compressive strength of mortars with partial replacement of the fine aggregate by crushed porcine bone (CPB) to assess the feasibility of their application in the construction sector. For this purpose, 162 mortar cubes were manufactured, with different substitution levels (2- 10%) tested at 7, 14, and 28 days. According to the results obtained, the highest compressive strength was found for the cubes with 2% CPB substitution and a lower strength for the cubes with 10% substitution, demonstrating an inversely proportional relationship between the percentage of fine aggregate substitution by CPB (replacement of 0 gr, 44 gr, 88 gr, 132 gr, 176 gr, and 220 gr for the 9 mortar cubes) and the compressive strength of the mortar. Likewise, it was possible to show that to prepare these mixtures, these required greater quantities of water compared to a conventional mortar, due to the greater absorption of the proposed replacement material. The objective of analyzing the behavior of porcine bone in cementitious mixtures is mainly due to the fact that this subject is scarce in the literature to date, which is why this type of research is important for the development of this new topic.
