摘要
为了处理堆积的锯泥,实现固废资源化利用,实验研究复合材料力学性能,试验工程应用.以水泥、石灰、粉煤灰作为改性材料,研究复合材料掺量和配合比对改性锯泥强度的影响.根据锯泥物理特性和化学特性,通过对锯泥掺入不同配比复合材料的方式对其进行改良,在浸水和不浸水条件下进行养护,测试不同方案的无侧限抗压强度.研究表明掺入复合材料可以有效提高锯泥强度,能够达到工程应用的技术要求,复合材料掺量为 6%时,既符合规范要求,且成本较低.
Abstract
In order to treat the piled-up saw mud and achieve solid waste resource utilization,the mechanical properties of the composites were investigated for engineering applications.Cement,lime and fly ash were used as modified materials to study the effect of the dosage of composite materials and proportion of mixture on the strength of modified saw mud.Based on the physical and chemical properties of the saw mud,improved the saw mud by way of mixing it with different ratios of composite materials.Maintenance was carried out under immersed and non-immersed conditions to test the unconfined compressive strength of the different solutions.The study shows that mixing composite materials can effectively improve saw mud's strength and meet engineering application technical requirements.The doping of composites at 6%meets both the specification requirements and has a low cost.
