项目摘要

An industry by-product is discharged in the circulation type society with fine grain or powder types. Moisture content of the by-product influences the properties of concrete. The purpose of this study is to evaluate the performance of water-retention, and the storage of the by-products. So, the collection of the fundamental data and an experiment were enforced. A molten slag, a siliceous powdered waste and a waste clay roof tiles were made the target by the research. Furthermore, use to the way base course material for pavement was examined, too.The following studies were conducted in this research.(1)Molten SlagThe performance of water-retention of molten slag is equality to fine aggregate. As for wet condition to mixing, correspondence is possible by the compensation of the surface moisture.(2)Siliceous Powdered WasteThe performance of water-retention of siliceous powdered waste is bigger than a usual fine aggregate. A capacity of it becomes small in comparison with the dryness cond … More ition under the wet condition. The discharge of the water is difficult because the performance of water-retention is high when it absorbs the water once. It is returned in the powder when it dries the siliceous powdered waste of wet condition.(3)Waste Clay Roof TilesAs for the raw material of the same quality as well, the waste clay roof tiles has the much difference brings about in the density and the absorption by the difference in the grain diameter after smashing.Performance of fresh concrete can be controlled as well as usual fine aggregate. The properties of the harden concrete are equal to the usual concrete, too. But, an elastic modulus declines caused by the increase in the mixing rate.Both the water absorbing performance and the drainage performance are high.(4)Evaluating the performance of water-retention of the by-product of fine grain or powder types.It is possible that it eases heat island phenomenon by cramming various by-products in soil-bag and laying it. Molten slag is shown as suitable water-retention material. Less

一种工业副产品以细颗粒或粉末状排入循环型社会。副产物的含水量影响混凝土的性能。本研究的目的是评估保水性能，以及副产物的储存。因此，收集基础数据并进行实验。以熔融炉渣、硅质粉料和粘土质屋面瓦废料为研究对象。此外，本研究亦探讨其作为路面基层材料之应用。（1）熔渣熔渣的保水性能与细集料相当。至于湿润条件对混合的影响，则可以通过表面水分的补偿来实现。（2）硅质粉料硅质粉料的保水性能比一般细骨料大。与干燥条件相比，其容量变小。 ...更多信息在潮湿的条件下。吸水一次，保水性能高，排水困难。当它干燥潮湿条件下的硅质粉末状废物时，它以粉末形式返回。（3）废粘土屋面瓦对于同样质量的原材料，废粘土屋面瓦由于粉碎后粒径的不同，在密度和吸水性上有很大的差异，新拌混凝土的性能可以和普通细骨料一样控制。硬化混凝土的性能与普通混凝土相当。但是，弹性模量随着混合率的增加而下降，吸水性能和排水性能都很高。（4）对细颗粒或粉末状副产物的保水性能进行了评价，认为将各种副产物装入土袋中并铺设，有可能缓解热岛现象，熔融炉渣是比较合适的保水材料。少
