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

对废弃玻璃瓶粉作细骨料的混凝土进行了5年龄期强度试验。火山灰反应能提高混凝土强度，且5年龄期强度增长率高于1年龄期。特别是当玻璃取代率为10%时，强度增加率最高。从污泥熔融炉渣作为粗集料的物理性能测试结果来看，污泥熔融炉渣作为粗集料的磨耗率和压碎值较高，强度低于碎石。吸水率满足JIS标准，但高于碎石。当混凝土中掺加相同量的化学外加剂时，新拌混凝土的坍落度和含气量增加， 关于我们 混凝土强度随矿渣取代率的增加而降低。混凝土的干燥收缩不受矿渣掺量的影响，但其抗冻融性能随矿渣掺量的增加而降低。与普通混凝土相比，200万次抗压疲劳强度略有下降。JSCE混凝土结构、路面标准规范疲劳强度方程中，假定“K”为10时，生存概率保证为95%以上。污水污泥熔渣作为细骨料的物理性能测试结果满足JIS标准。污泥熔融矿渣作为细集料的混凝土，随着矿渣取代率的增加，凝结时间提前，泌水率增加。矿渣掺量为100%的混凝土强度与掺量为0%的混凝土强度相当。抗冻融性能基本相同，且与矿渣替代率无关。在完成300次循环时，矿渣替代率100%的混凝土和0%的混凝土的质量减少率相同，25%、50%和75%的混凝土是0%的混凝土的5至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.
