The Effective Use of Life Waste, Abolition Glass Bottle and Sewage Sludge Molten Slag, as Material for Concrete

对废弃玻璃瓶粉作为细骨料的5年龄期混凝土进行了强度试验。火山灰反应提高了混凝土的强度，且5年龄期的强度提高率高于1年龄期的强度提高率。当玻璃取代率为10%时，强度提高率最高。但5日龄割线弹性模量的下降幅度小于1日龄，与91日龄基本持平。从污泥熔渣粗集料物性试验结果看，其磨损率和破碎值较高，且作为粗集料的熔渣强度低于碎石。吸水率满足JIS标准，但高于碎石。在掺量相同的化学外加剂条件下，随着矿渣替代比的增加，新拌混凝土的坍落度增大，掺量增加，混凝土强度降低。矿渣替代比对混凝土的干缩性能没有影响，但随着矿渣替代比的增大，混凝土的抗冻融性能降低。与普通混凝土相比，200万次循环的抗压疲劳强度略有下降。在JSCE混凝土结构铺装标准规范疲劳强度方程中，假设K = 10，保证存活概率在95%以上。污水污泥熔渣作为细骨料的物性测试结果满足JIS标准。污泥熔渣为细骨料的混凝土凝结时间早，随渣替代比的增加，混凝土泌水率增大。矿渣替代率为100%的混凝土与0%的混凝土强度基本相等。抗冻融性能基本相同，且与渣替代比无关。在完成300次循环时，矿渣替代率为100%的混凝土与0%混凝土的质量减量比相同，25%、50%、75%混凝土的质量减量比为0%混凝土的5 ~ 8倍。少

Strength tests of concrete at the 5-year age including abolition glass bottle powder as a fine aggregate were carried out. Strength of the concrete was increased with pozzolanic reaction, and the ratio of strength increase to the 5-year age was higher than it to the 1-year age. Especially, the highest ratio of strength increase was observed when glass substitution ratio was 10%. However, the secant modulus of elasticity at the 5-year age decreased less than that at the 1-year age and almost equal with that at the 91-day age.From test results of physical property of sewage sludge molten slag as a coarse aggregate, the percentage of abrasion and the crushing value were higher, and the strength of the slag as a coarse aggregate was lower than the crushed stone. And the percentage of water absorption satisfied the JIS standard, but it was higher than the crushed stone. The slump and the air content of fresh concrete, when using the same amount of chemical admixture for concrete, were incre … More ased and the strength of concrete was decreased with increase of slag substitution ratio. The drying shrinkage of concrete was not influenced of slag substitution ratio, but the freeze-thaw resistance was decreased with increase of slag substitution ratio. The compressive fatigue strength at two million cycles decreased a little when compared with the normal concrete. The survival probability was guaranteed for 95% or more when the "K" was assumed to be 10 on the equation of fatigue strength of standard specifications for concrete structures, paving of JSCE.The test result of physical property of sewage sludge molten slag as fine aggregate satisfied the JIS standard. The time of setting concrete using sewage sludge molten slag as a fine aggregate became early and the bleeding ratio was increase with increase of slag substitution ratio. The strength of the slag substitution ratio 100% concrete was almost equal with the 0% concrete. The freeze-thaw resistance was in the same, and it was not related with slag substitution ratio. At the time of completion 300 cycles, the mass decrease ratio of the slag substitution ratio 100% concrete and the 0% concrete were in the same and the 25%, 50% and 75% concrete were 5 to 8 times of the 0% concrete.
