This study evaluates the potential use of glass powder residue as partial replacement of cement in the fibers cement industry. Fibers cement composites were elaborated according to slurry dewatering method. Three formulations were studied; two cementitious matrices with a partial replacement of cement by glass powder residue (20 and 50% by weight) and a cementitious matrix with a partial replacement of cement by 20% by weight of limestone (commonly used as mineral addition in the fibers cement industry). The effect of these mineral additions on the cement hydration was evaluated using isothermal calorimetry. Physico-mechanical properties of the composites were determined at 8 days and after durability tests. Moreover, the potential application of the glass powder residue into the fibers cement industry was evaluated by determine the energy demand of the production of cement and the energy performance of fibers cement composites elaborated from the glass powder residue.

The results showed that cement pastes containing the glass powder residue present a higher heat of hydration in comparison to the control. The partial replacement of cement by 50% by weight of glass powder residue increases the flexural strength of composites at 8 days and after durability tests. The results also showed that the production of 1 ton of cement partially replaced by glass powder residue requires lower energy than the cement partially replaced by limestone. Finally, according to the study, the use of the glass powder residue in production of fibers cement composites can provide important technical, environmental and economic benefits.

这项研究评估了玻璃粉残留物在纤维水泥工业中作为水泥的部分替代品的潜在用途。根据浆液脱水法对纤维水泥复合材料进行了细化。研究了三种配方；两种水泥基质，其中一部分被玻璃粉渣（20和50％重量）代替，另一种是水泥基质，其中一部分水泥被20％重量的石灰石代替（在纤维水泥工业中通常用作矿物添加剂） 。使用等温量热法评估了这些矿物质添加对水泥水化的影响。在8天和耐久性试验之后确定复合材料的物理-机械性能。此外，

结果表明，与对照相比，含有玻璃粉残留物的水泥浆具有更高的水合热。用重量百分比为50％的玻璃粉末残余物部分替代水泥，可以提高复合材料在8天及耐久性试验后的抗弯强度。结果还表明，与部分被石灰石替代的水泥相比，生产1吨被玻璃粉残渣部分替代的水泥所需的能源更低。最后，根据研究，在纤维水泥复合材料生产中使用玻璃粉残留物可提供重要的技术，环境和经济效益。
