This article presents an overview of the bibliographic picture of the design parameter's influence on the mix proportion of self-compacting concrete with recycled aggregate. Design parameters like water-cement ratio, water to paste ratio, and percentage of superplasticizers are considered in this review. Standardization and recent research on the usage of recycled aggregates in self-compacting concrete (SCC) exploit its significance in the construction sector. The usage of recycled aggregate not only resolves the negative impacts on the environment but also prevents the usage of natural resources. Furthermore, it is necessary to understand the recycled aggregate property's role in a mixed design and SCC properties. Design parameters are not only influenced by a mix design but also play a key role in SCC's fresh properties. Hence, in this overview, properties of SCC ingredients, calculation of design parameters in mix design, the effect of design parameters on fresh concrete properties, and the evolution of fresh concrete properties are studied.
本文概述了设计参数对再生骨料自密实混凝土配合比影响的文献情况。本综述考虑了水灰比、水胶比和高效减水剂百分比等设计参数。自密实混凝土(SCC)中再生骨料使用的标准化和近期研究凸显了其在建筑领域的重要性。再生骨料的使用不仅解决了对环境的负面影响,还避免了自然资源的使用。此外,有必要了解再生骨料性能在配合比设计和自密实混凝土性能中的作用。设计参数不仅受配合比设计的影响,还在自密实混凝土的新拌性能中起关键作用。因此,在本综述中,研究了自密实混凝土成分的性能、配合比设计中设计参数的计算、设计参数对新拌混凝土性能的影响以及新拌混凝土性能的演变。
