This study evaluates the effect upon the compressive strength of ceramic masonry bricks when industrial byproducts known as soot are added. The research includes an analysis of the granulometric properties of the constituent components, performed manually with ASTM C136‐01 screens to determine particle size using apertures sized from large to small; an analysis by XRD of the mineralogical phases present; a compressive strength analysis performed using standard compression testing machinery; and a water absorption measurement calculated according to Colombian Technical Standard: 4017:2015—Methods for the Sampling and Testing of Masonry Elements and other Clay Products. Five trials were performed using different mixtures of clay and soot, at substitution rates of 20%, 30%, 40%, 50%, and 60%. These mixtures were prepared under identical conditions in order to ensure validity of the resulting comparisons. The results showed that bricks with 20%, 30%, 40%, and 50% added soot demonstrated superior structural strength compared to conventional units. Bricks incorporating 60% soot, however, were found to have lower strength and high porosity.

工业副产品骨料生产的Mansory砖的抗压评估

这项研究评估了添加工业副产品烟尘时对陶瓷砖的抗压强度的影响。该研究包括对组成成分的粒度特性的分析，该分析是使用ASTM C136-01筛网手动进行的，以使用从大到小尺寸的孔径来确定粒径。通过XRD对存在的矿物相进行分析; 使用标准抗压试验机进行抗压强度分析；根据哥伦比亚技术标准4017：2015计算的吸水率，该方法是对砖石元素和其他粘土产品进行抽样和测试的方法。使用黏土和烟灰的不同混合物进行了五项试验，替代率为20％，30％，40％，50％和60％。在相同条件下制备这些混合物，以确保所得比较的有效性。结果表明，与传统单元相比，添加了20％，30％，40％和50％烟灰的砖块显示出更高的结构强度。然而，发现掺有60％烟灰的砖具有较低的强度和高的孔隙率。
