The extensive consumption of clayey soils to manufacture bricks has caused the depletion of these non-renewable natural resources. In this paper, in a bid to reduce clay consumption and recycle waste glass, 20 wt% crushed household glass was added to clayey soils from Jun and Guadix (Granada, Spain) to manufacture handmade and extruded bricks fired at 800, 950 and 1100 °C. The presence of carbonates in the soil from Jun favored the development of new Ca-(Mg) silicates such as gehlenite, diopside, wollastonite and anorthite, while mullite developed in the bricks made with clay from Guadix. The addition of glass altered the porous system of the bricks, which absorbed less water and dried more quickly than conventional bricks. As regards the manufacturing procedure, extruded bricks turned out to be less porous than handmade ones. The porosity of both handmade and extruded bricks fell as the firing temperature increased. Bricks with added glass were more resistant to compressive strength tests than those made exclusively with clay. These results were confirmed by ultrasound measurements from which we observed that the compactness of bricks increases in line with the increase in the firing temperature and by adding glass. Accelerated ageing tests (freeze-thaw, salt crystallization and wet-dry) revealed that the addition of glass provides the bricks with more compactness, strength and durability than those without glass fired at the same temperature. 20 wt% proved to be the ideal proportion for waste glass added to the clay used in the production of high-quality compact bricks.

大量消耗粘土来制造砖块已经导致这些不可再生自然资源的枯竭。在本文中，为了减少粘土消耗和回收废玻璃，将 20 wt% 的碎家用玻璃添加到 Jun 和 Guadix（西班牙格拉纳达）的粘土中，以制造在 800、950 和 1100° 烧制的手工砖和挤压砖C。Jun 土壤中碳酸盐的存在有利于新的 Ca-(Mg) 硅酸盐的发展，例如钙长石、透辉石、硅灰石和钙长石，而莫来石则在用 Guadix 的粘土制成的砖中发展。玻璃的加入改变了砖的多孔系统，与传统砖相比，它吸收的水更少，干燥得更快。至于制造过程，事实证明，挤压砖比手工砖的多孔性要小。手工砖和挤压砖的孔隙率都随着烧成温度的升高而下降。添加玻璃的砖比仅用粘土制成的砖更能抵抗抗压强度测试。这些结果通过超声波测量得到证实，我们从中观察到砖的致密性随着烧制温度的增加和添加玻璃的增加而增加。加速老化试验（冻融、盐结晶和湿干）表明，在相同温度下，添加玻璃的砖比没有玻璃的砖具有更高的致密性、强度和耐用性。20 wt% 被证明是添加到用于生产高质量致密砖的粘土中的废玻璃的理想比例。
