Abstract

To reduce the negative environmental impacts of waste glass, this research aims to incorporate mixed types of municipal waste glass in cement block mortars. The waste glass was first crushed, milled and screened with #18 and #20 meshed sieves to obtain the waste glass powder (WGP). The WGP, grouped into 3 sizes; smaller (P#20WGP; 95% finer than 125 μm) and larger than #20 mesh-sieve (T#20WGP), as well as an equal mix of both sizes (M#20WGP), was used to replace sand in 0-100% ranges. The specific strength of mortars was enhanced by increasing the WGP contents. X-ray diffraction analysis suggested that carbonation at the early age observed in the P#20WGP-mortars could accelerate strength development. The extended working time test showed that the fresh WGP-mortars had the potential for casting in the first 120 min. The hand ramming method of the mortars using different amounts of WGP did not show a significant difference in mechanical properties suggesting that WGP could replace sand at all percentages. The surface temperature change, as a function of solar irradiated time, of both mortar blocks was similar.

用市政废玻璃混合制成的铺路砌块砂浆

为了减少废玻璃对环境的负面影响，本研究旨在将混合类型的城市废玻璃掺入水泥砌块砂浆中。将废玻璃先粉碎、磨粉，用18号和20号网筛筛分，得到废玻璃粉(WGP)。WGP，分为3个尺寸;小(P # 20生产总值;在0 ~ 100%的范围内，使用小于125 μm的95%细粒和大于20 #筛网(T#20WGP)，以及两种粒径的均匀混合(M#20WGP)来代替砂粒。增加WGP的含量可以提高砂浆的比强度。x射线衍射分析表明，p# 20wgp -砂浆早期碳化作用加速了其强度的发展。延长工作时间试验表明，新鲜的WGP-砂浆在前120分钟内具有浇筑的潜力。使用不同数量的WGP的砂浆的手夯法在力学性能上没有显着差异，表明WGP可以在任何百分比替代砂。两种砂浆砌块表面温度随太阳照射时间的变化相似。

期刊介绍： Waste and Resource Management publishes original research and practice papers on all civil engineering and construction related aspects of the resource management cycle, from the minimization of waste, through the re-use and recycling, to the management and disposal of residual wastes. Associated legislation, standards, socio-economic considerations and links with sustainable consumption and production are included. The range of subjects covered encompasses, but is not restricted to, strategies for reducing construction waste through better design, improved recovery and re-use, more efficient resource management, the performance of materials recovered from wastes, and, the procurement, planning, design, construction, operation and logistics of waste and resource management facilities.
