Research on Recycle of Living and Industrial Wastes as a Constracting Materials

1.空罐轻填材料的回收利用(1)开发了空罐内的塑料单元，构建了塑料单元的轻填料，并对交通负荷进行了操作。交通试验结果表明，9个空罐内的塑料单元制成的轻质充填体能够承受D型交通(12t轮重)。(2)通过1个月至9年的自然天气下暴露的空罐抗冲刷试验结果，判断5年内无任何防侵蚀的塑料单元可用作临时轻填土路堤。利用粉煤灰、火山灰和聚苯硫醚废料进行建筑材料的回收利用(1)研制了以粉煤灰、火山灰和粘土为主要原料的新型瓷砖。(2)以粉煤灰、聚苯乙烯废料、硅酸盐水泥和水为原料，研制了新型建筑材料(以下简称聚苯硫醚废料灰)。对…进行了室内无侧限抗压试验和渗透试验对不同配合比、不同养护时间的EPS废灰试件进行了CBR试验。从EPS废灰的室内测试结果来看，EPS废灰的混合比(水泥与飞灰的质量比，C/F&GT；17%，EPS与FA&lt的质量比；(3)进行了EPS灰分调节C/F=20%、EPS/F=0.5%的软基改良薄层1g小比尺地基模型试验。地基模型试验结果表明，随着EPS废渣薄层厚度D_f和宽度B的增加，加固后的软土地基的承载力Q_d增大。在粘性土地基深度D=50 cm、基础宽度b=10 cm、B=20 cm的条件下，土层厚度D=50 cm、基础宽度b=10 cm、B=20 cm时，地基承载力比未加筋地基提高2.4倍、3.0倍。(4)通过模型试验和计算结果的对比，确定了弹粘塑性有限元模型参数，为现场缩尺模拟试验设计提供了指导。较少

1.Recycle of empty tins as Light-Fill Materials(1) The plastic unit within the empty tins was developed and the light-fill made by the plastic unit was constructed and traffic load was operated. As the results of traffic experiments, the light-fill made by the plastic unit within the 9 empty tins was clarified to be able to sustain D type traffic (12t wheel load).(2) As the results of the proof erosion tests of empty tins exposed under the natural weather during 1 month to 9 years, It has been judged that the plastic units without any proof erosion can be used as the temporary light-fill load embankment within 5 years.2. Recycle of coal ash, volcanic ash and EPS wastes as a constructing materials(1) New tile mixed by coal ash, volcanic ash and clay was developed.(2) New constructing material(hereafter, called EPS wastes ash)mixed by coal ash, EPS wastes, Portland cement and water was developed.Laboratory investigation was carried out unconfined compression tests and penetration tests a … More s like as CBR tests on the EPS wastes ash specimen with various conditions of mix proportion, and curing time.From the results of laboratory testing of EPS waste ash, the mix proportion of compertibility (the mass ratio of cement to Fly ash (FA) , C/F>17%, the mass ratio of EPS wastes to FA<0.5%) and curing time (28 days) for the thin layr improvement material for soft clay ground were determined.(3) The 1g small scale footing model tests for the soft clay ground improved thin layr with the EPS wastes ash regulated C/F=20% and EPS/F=0.5% was carried out. As the results of the footing model test, the bearing capacity, q_d of the improved soft ground is increasing with increase of the depth, D_f and width, B of thin layr of the EPS waste ash. The increase of bearing capacity to compare with unreinforced ground is 2.4 times at Df/D=0.044, and 3.0 times at Df/D=0.11 under the condition of the clay ground depth, D=50cm, the footing width, b=10cm and B=20cm.(4) The model parameters of the elasto-visco/plastic FEM were determined with the comparison of both model tests and calculated results for the design guide of the soft clay ground improved thin layr with the EPS wastes by in-situ scale simulations.
