Abstract

River sand is becoming increasingly scarce. As a result, an alternative material is required to replace river sand in order to save river sand. In the construction of quality concrete, artificial aggregate is now frequently employed as a substitute for river sand. Coconut fibre ash (CFA) aggregate obtained from Coconut fibre is prev - alent in India. Partially replacing river sand (fine aggregate) with presaturated CFA aggregate for self curing purpose is presented in the paper. Fine aggregates were replaced by CFA aggregate by 5%, 10%, 15%, 20% and 25% by volume. The workability and strength characteristics of the concrete are studied. Internal curing is the solution to today's water scarcity's insufficient curing. During compared to other mixtures, test results show that the concrete mix with 20% CFA aggregate produced better results when self curing.
预饱和椰子纤维灰粒对混凝土性能的影响
河沙越来越少了。因此,为了节约河砂,需要一种替代材料来代替河砂。在高质量混凝土的施工中,人工骨料现在经常被用作河砂的替代品。从椰子纤维中提取的椰子纤维灰分(CFA)骨料在印度很普遍。本文提出用预饱和CFA骨料部分替代河砂(细骨料)自养护。细骨料用CFA骨料代替,体积比分别为5%、10%、15%、20%和25%。研究了混凝土的和易性和强度特性。内部养护是当今水资源短缺的解决方案,养护不足。试验结果表明,掺加20% CFA骨料的混凝土自养护效果较好。
