摘要

在过去十年中,由于环境敏感性的提高,回收骨料的使用大大增加。这些材料所要求的性能水平取决于它们的应用。许多回收建筑废物在各种岩土工程应用方面具有足够的抗剪强度。然而,这些材料的一个可能的缺点是在重复加载过程中有破碎的危险。本文研究了两种废弃物:破碎混凝土和建筑碎片,它们都被视为建筑垃圾。还对传统上使用的碎石进行了测试,在这种情况下是玄武岩。这些材料在大型直剪装置中经受了反复加载。破碎量是通过对测试材料进行粒度分析来量化的。结果表明,两种再生建筑垃圾均易发生颗粒破碎。压碎量受垂直压力和…

REUSE OF CONSTRUCTION WASTE: PERFORMANCE UNDER REPEATED LOADING
The use of recycled aggregates has increased greatly over the last decade owing to enhanced environmental sensitivities. The level of performance required by such materials is dependent upon the applications for which they are used. Many recycled construction wastes have adequate shear strength in relation to various geotechnical applications. However, a possible drawback of these materials is the risk of crushing during repeated loading. The work reported in this paper examined two waste materials: crushed concrete and building debris, both regarded as construction wastes. Tests were also performed on traditionally used crushed rock, in this case basalt. The materials were subjected to repeated loading in a large direct shear apparatus. The amount of crushing was quantified by performing particle size analysis of the tested material. The results have shown that both recycled construction wastes were susceptible to particle crushing. The amount of crushing was influenced by both the vertical pressure and ...

期刊介绍: The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
