Abstract

ABSTRACT This paper presents the results of a testing program to examine the possibility of using crushed clay bricks as fine aggregate in concrete and mortar mixtures. A total of 90 specimens of concrete and mortar were cast at different percentages of crushed bricks (0, 25, 50, 75, and 100)% by weight as replacement of fine aggregate. Mechanical and physical properties of the specimens were conducted and presented in this paper. The experimental results indicated a decrease in compressive strength and splitting tensile strength of the concrete specimens. Also, the presence of crushed bricks aggregate in mixtures reduces the workability and flow ratio compared to the reference mix due to high water demand of the recycled aggregates than the normal aggregate. It can be noted that crushed bricks concrete is a convenient replacement in treading and finishing areas in buildings and in high floors in order to reduce the dead loads.

破碎粘土砖作为混凝土和水泥砂浆细骨料的回收利用

摘要:本文介绍了一个测试程序的结果，以检查在混凝土和砂浆混合物中使用破碎的粘土砖作为细骨料的可能性。总共有90个混凝土和砂浆样品以不同比例的碎砖(0、25、50、75和100)的重量来代替细骨料。本文对试样的力学和物理性能进行了研究。试验结果表明，混凝土试件的抗压强度和劈裂抗拉强度均有所降低。此外，与参考混合料相比，由于再生骨料比普通骨料需水量高，因此在混合物中存在碎砖骨料降低了和易性和流动比。需要指出的是，碎砖混凝土是一种方便的替代品，用于建筑物的踏面和精装区域，以减少高层的自重。

期刊介绍： The Australian Journal of Structural Engineering (AJSE) is published under the auspices of the Structural College Board of Engineers Australia. It fulfils part of the Board''s mission for Continuing Professional Development. The journal also offers a means for exchange and interaction of scientific and professional issues and technical developments. The journal is open to members and non-members of Engineers Australia. Original papers on research and development (Technical Papers) and professional matters and achievements (Professional Papers) in all areas relevant to the science, art and practice of structural engineering are considered for possible publication. All papers and technical notes are peer-reviewed. The fundamental criterion for acceptance for publication is the intellectual and professional value of the contribution. Occasionally, papers previously published in essentially the same form elsewhere may be considered for publication. In this case acknowledgement to prior publication must be included in a footnote on page one of the manuscript. These papers are peer-reviewed as new submissions. The length of acceptable contributions typically should not exceed 4,000 to 5,000 word equivalents. Longer manuscripts may be considered at the discretion of the Editor. Technical Notes typically should not exceed about 1,000 word equivalents. Discussions on a Paper or Note published in the AJSE are welcomed. Discussions must address significant matters related to the content of a Paper or Technical Note and may include supplementary and critical comments and questions regarding content.
