The availability of different lithology with which concrete can be packaged could create substantial questions on the differences that they can provide to the same mixture. Different kinds of aggregates were analyzed individually to investigate their main characteristics, which allowed us to package five types of concrete mixtures. These five mixtures were compared to each other through compressive strength values. Furthermore, it was considered microscopically what possible differences could exist between these different mixtures, for example, differences in the cement/aggregate reaction. The chemical characterization of the aggregates, used as the skeleton of the cement mixes, was proposed as an important investigative phase in order to better understand the differences in the geotechnical and physical-mechanical characteristics and to verify the presence of any harmful phases for the durability of the concrete.
用于包装混凝土的不同岩性的可用性可能会引发关于它们对同一混合物所能提供的差异的大量问题。对不同种类的骨料分别进行分析以研究其主要特性，这使我们能够配制五种类型的混凝土混合物。通过抗压强度值对这五种混合物进行相互比较。此外，从微观角度考虑了这些不同混合物之间可能存在的差异，例如水泥/骨料反应的差异。作为水泥混合料骨架的骨料的化学特性被提议作为一个重要的研究阶段，以便更好地理解岩土和物理力学特性的差异，并验证是否存在对混凝土耐久性有害的任何相。
