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.

在5岁时进行的混凝土强度测试，包括废除玻璃瓶粉作为细骨料。混凝土的强度随火山灰的反应增加，并且强度增加与5岁年龄的比率高于1岁。特别是，当玻璃取代比为10％时，观察到最高的强度增加。然而，五岁时的弹性弹性模量低于1岁年龄的弹性降低，几乎与91天的年龄相等。从污水污泥的物理特性熔化的物理特性作为粗骨料的测试结果，磨损的百分比，碎屑值和碎屑值更高，而碎裂的强度则是粗凝块的强度。吸水的百分比满足了JIS标准，但它比碎石高。当使用混凝土干燥收缩时，新鲜混凝土的倒塌和空气含量不受炉渣取代率的影响，但是随着炉渣替代比的增加，冻融耐药性降低了。与正常混凝土相比，200万个周期时的压缩疲劳强度略有下降。当假定“ K”在混凝土结构的标准规格的疲劳强度，JSCE粘贴的标准规格方程中，将“ K”保持在95％或更高。污水污泥熔融炉灶的物理特性的测试结果是良好的总骨料。使用污水污泥熔融矿渣作为细骨料的固定时间较早，并且随着炉渣取代比的增加而增加了出血比。炉渣取代比100％混凝土的强度与0％混凝土几乎相等。冻融耐药性也一样，与炉渣取代率无关。在完成300周期时，炉渣取代率的质量减小比100％混凝土和0％混凝土在同一，而25％，50％和75％混凝土为0％混凝土的5至8倍。较少的
