钦博拉索省的一项重要经济活动是粘土砖、砌块、铺路材料和石质材料（骨料）等建筑材料的制造和生产。这些材料必须满足最低质量要求，以确保适当的机械性能，并且不会缩短民用建筑的使用寿命。本研究对2012年至2015年全省所有工厂生产的粘土砖、混凝土砌块、铺路砖和混凝土用天然骨料的质量进行了评估。将获得的结果与厄瓜多尔标准化研究所 (INEN) 提供的质量标准进行比较。所有物理和机械性能表征的测试程序均遵循美国测试与材料协会 (ASTM) 和英国标准协会 (BSI) 制定的指南。本文介绍了钦博拉索州 10 个区（州）258 家工厂生产的建筑材料的质量评估结果。研究表明，混凝土铺路砖和骨料的性能优于粘土砖和混凝土块。混凝土砌块样品的不符合规格百分比最高，结果分布也最广泛。钦博拉索各区都发现建筑材料生产存在质量问题。
An important economic activity in the province of Chimborazo is the manufacture and production of construction materials such as clay bricks, blocks, pavers and petrous materials (aggregates). These materials must meet minimum quality requirements to ensure proper mechanical behaviour and not reduce the lifespan of civil constructions. In this study, the quality of clay bricks, concrete blocks, paving bricks and natural aggregates for concrete produced in all the factories of the province from 2012 to 2015 was assessed. The results obtained were compared with the quality standards provided by the Ecuadorian Institute of Standardisation (INEN). All testing procedures for characterisation of physical and mechanical properties followed the guidelines set by the American Society for Testing and Materials (ASTM) and the British Standards Institution (BSI). This paper presents the outcomes of the quality evaluation of construction materials produced in 258 factories located in the ten districts (cantons) of Chimborazo. The study revealed that paving bricks and aggregates for concrete performed better than clay bricks and concrete blocks. The samples of concrete blocks had the highest percentage of non-compliance specifications and the widest spread of results. Quality problems in the production of construction materials were found in all the districts of Chimborazo.
