Abstract

Abstract The main problem is to raise the standard of construction, rethinking concrete's expanding potential as a construction material. The scarcity of river sand as a fine aggregate ingredient is currently a widespread issue for many concrete plants. As a result, quarried stones that were accessible locally were used as fine aggregate. Crushed Rock Particles, also known as crushed sand, performs better in terms of fresh characteristics since there are more fines present in CRF than in river sand. The current study additionally examines the relationship between plastic viscosity and the fresh and hardened SCC properties. As a partial substitute for Ordinary Portland Cement, Fly Ash and Ground Granulated Blast Slag blends are used to generate binary and ternary. The experimental tests satisfactorily validate the suggested blend design. The results shown that SCC mixture with ternary blend, binary blend with GGBS, fly ash, and blend with pure OPC are suitable for creating fresh characteristics. Additionally, it was found that a cohesive and workable mix was produced when 100 % CRF was used in place of sand.

基于流变配合比的高强自密实混凝土力学性能研究

主要问题是提高施工标准，重新思考混凝土作为一种建筑材料的发展潜力。河砂作为一种细骨料原料的稀缺性是目前许多混凝土厂普遍存在的问题。因此，当地可获得的采石被用作细骨料。碎石颗粒，也被称为碎砂，在新鲜特性方面表现得更好，因为CRF中比河砂中存在更多的细粒。目前的研究还研究了塑性粘度与新鲜和硬化SCC性能之间的关系。作为普通硅酸盐水泥的部分替代品，粉煤灰和磨碎的矿渣共混物被用来生产二元和三元水泥。实验试验满意地验证了所建议的共混设计。结果表明，SCC与三元共混物、GGBS二元共混物、粉煤灰共混物、纯OPC共混物均适合创造新特性。此外，当使用100% CRF代替砂土时，发现产生了一种粘性和可行的混合物。

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.
