Abstract

Due to rapid urbanization there is a great increase in building construction, so is the demoli-tion. There is no proper disposal of the demolition waste. About 530 million tons of C&D waste is generated annually. But only a few amounts of demolished concrete is recycled or reused. In this study, experimental investigations have been carried out to evaluate the effect of complete replacement of fine aggregate by dem-olition waste on compressive strength, which is compared with a conventional block. The concrete blocks were made in M20 mix. Further, the test was carried out in concrete paver block, in M40 mix design. The concrete paver blocks show 91% strength attainment at 28 days and it is only a marginal deterioration in the compressive strength. Therefore, the concrete blocks made with demolition waste can be used in low load bearing pavements.

利用再生拆除废料生产混凝土铺路砖

由于快速的城市化，建筑建设大增，拆迁也大增。拆迁垃圾没有得到妥善处理。每年产生约5.3亿吨拆建垃圾。但只有少量被拆除的混凝土被回收或重复使用。在本研究中，进行了实验研究，以评估用沸石废料完全取代细骨料对抗压强度的影响，并与传统砌块进行了比较。混凝土砌块是用M20混合料制成的。此外，在M40配合比设计中，在混凝土摊铺机块上进行了试验。混凝土摊铺机砌块在28天时显示出91%的强度，并且这只是抗压强度的边际退化。因此，利用拆迁垃圾制成的混凝土砌块可用于低承载力路面。

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
