摘要

本研究提出的目的是使用可持续材料,如拆除旧建筑的碎砖作为添加剂,以保护环境,减少能源消耗,降低混凝土成本,改善混凝土的性能,并获得高层建筑的轻质混凝土,在狭窄的地方有更多的流动性。此外,由于对最佳替代比率的了解仍然不多,因此讨论了最佳替代比率。使用并测试了三种混凝土混合料。以mix- 1为标准,其中mix-2采用碎砖骨料替代粗骨料,mix-3研究粉砖替代细骨料。在此分析中,只考虑了两个因素:砖骨料替代粗骨料的百分比(从0到50%)和砖骨料替代细骨料的百分比(从0到75%)。在龄期(7天和28天)养护后测试抗压强度。结果表明,砖骨料破碎后的混凝土降低了混凝土的单位重量,提高了混凝土的抗压强度。混合料-2在(7、28)日龄时抗压强度分别提高约9.7%和7%,重量减轻11%。混合料-3在龄期(7日龄和28日龄)抗压强度分别提高了59%和61%,重量降低了2%。

Using recycled bricks to improve the compressive strength of concrete and produce lightweight concrete
This research presents the aim of using sustainable materials like crushed bricks from the demolition of old buildings as additives to preserve the environment, reduce energy consumption, reduce the cost of concrete, improve the properties of concrete, and obtain lightweight concrete for high buildings with more fluidity for narrow places. Also, it discusses the best replacement ratios because the knowledge about them is still lake. Three mixes of concrete were used and tested. Mix-1was the standard, where the replacement of coarse aggregate with crushed brick aggregate has been used in mix-2, the mix-3 was to study the replacement of fine aggregate by powder brick. In this analysis, only two factors were taken into account: the percentage of coarse aggregate replaced by brick aggregate (from 0 to 50%) and the percentage of fine aggregate replaced by brick aggregate (from 0 to 75%).  Compressive strength was tested after curing at ages (7, and 28) days. The results showed that concrete with crushed brick aggregate reduces unit weight and increases of compressive strength of concrete. Using mix-2 increased the compressive strength by about 9.7%, and 7% at ages (7, 28) days respectively, and reduced the weight by 11%. Also, using mix-3 increased the compressive strength with high percentages of about 59%, and 61% at ages (7, and 28) days respectively, with a little percentage of reducing the weight by 2%.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
