| dc.description.abstract | When industrial products go mass production, it also brings a large amount of wastes need to be disposed of. If the recycling measure is insufficient, both the living environment and enterprise development will be badly affected. On the other hand, due to the limitation in mining natural aggregates, the demand in aggregates remains high and the cost keeps increasing. Therefore, the use of industrial wastes as a replacement for natural aggregates has became a critical issue. Many industrial wastes can be reprocessed as recycled aggregate, in order to replace natural aggregate. This will help to ease up the lacking in aggregate supplies.
This research is to examine the supply and demand of aggregates for the construction industry. The moving average approach was used to predict the demand in aggregates for the next 5 years. The demand in aggregates was analyzed individually for various applications, including road base aggregate, CLSM, plain concrete, the engineering fills, and ground improvement material. The results can be used as an analyzing basis. Nowadays the recycling techniques has greatly improved, many studies have demonstrated the suitability of recycled aggregates in engineering applications. Although the recycling skills have progressed a great deal, the lack of construction specifications and of confidence by potential users has limited the market development for waste applications. Three industrial wastes (TCS, EAF slag, cast-iron scrap, and incinerator fly ash) were selected to conduct a strategic planning. SWOT technique was used to analyze and evaluate the 3 cases to come up with best strategy to promote the use waste materials as aggregates. The results show that an environmental certificate will help in promoting the application of wastes in a positive way. | en_US |
