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

1.空罐作为轻质填料的回收利用（1）开发了空罐内的塑料单元，并构建了由塑料单元制成的轻质填料，并运行了交通负荷。交通试验结果表明，9个空罐内的塑料单元所形成的轻质填料能够承受D型交通（12 t轮载）。(2)根据空罐在自然气候条件下暴露1个月至9年的抗侵蚀试验结果，判断无任何抗侵蚀性的塑料单元可以在5年内用作临时轻填土路堤.粉煤灰、火山灰和EPS废弃物作为建筑材料的回收利用（1）研制了粉煤灰、火山灰和粘土混合的新型瓷砖。(2)以粉煤灰、EPS废弃物、波特兰水泥和水为主要原料，研制了一种新型建筑材料（EPS废弃物灰），通过室内无侧限抗压试验和贯入试验，研究了EPS废弃物灰的抗压强度、抗压强度和抗压强度对EPS废弃物灰抗压强度的影响。 关于我们 对不同配合比、不同养护时间条件下的EPS垃圾灰试件进行了CBR试验，从EPS垃圾灰的室内试验结果来看，（水泥与粉煤灰的质量比（FA），C/F> 17%，确定了EPS废弃物与FA的质量比（<0.5%）和固化时间（28天）。(3)对EPS废弃物灰比C/F=20%和EPS/F=0.5%的软土地基加固薄层进行了1g小比例模型试验。地基模型试验结果表明，EPS粉煤灰加固软土地基的承载力q_d随EPS粉煤灰薄层深度D_f和宽度B的增加而增加。当地基深度D= 50 cm，基础宽度B= 10 cm，B= 20 cm时，当Df/D =0.044时，地基承载力比未加固地基提高2.4倍;当Df/D=0.11时，地基承载力比未加固地基提高3.0倍。(4)通过室内模型试验与现场模拟计算结果的对比，确定了弹粘塑性有限元模型参数，为EPS废弃物加固软土地基的设计提供了依据。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.
