Abstract

Lime sludge is a residual substance came from the paper sector. The current research investigates that the effects of adding lime sludge to concrete as a cementitious substance on its mechanical properties. Lime sludge replaces cement in various amounts to provide the appropriate mechanical properties. The resulting material is then compared to standard concrete. The research on supplemental cementation resources that equivalent Portland cements's potency without compromising stability. According to the Indian standard (IS 10262–2009), the study used M20, M30, and M40 concrete. Lime sludge replaced cement 0 %, 10 %, 20 %, and 30 %. Also investigated were lime sludge and fly ash mixtures of 10 %, 20 %, and 30 % by weight. Mechanical parameters of concrete classes M20, M30, and M40 were measured at 7 and 28 days. The grades show that the 10 % lime sludge out performed normal concrete. This work represents can be applied as unique additional cementitious substance up to the definite proportions.

对掺入石灰渣和粉煤灰的二元混合水泥混凝土的系统分析

石灰污泥是造纸行业的一种残留物质。目前的研究调查了在混凝土中添加石灰污泥作为胶凝物质对其机械性能的影响。石灰污泥以不同的用量替代水泥，以提供适当的机械性能。然后将所得材料与标准混凝土进行比较。对补充胶凝资源的研究表明，等效波特兰水泥的效力不会影响稳定性。根据印度标准（IS 10262-2009），研究使用了 M20、M30 和 M40 混凝土。石灰污泥取代水泥的比例分别为 0%、10%、20% 和 30%。此外，还研究了石灰污泥和粉煤灰的混合物，重量百分比分别为 10%、20% 和 30%。在 7 天和 28 天时测量了 M20、M30 和 M40 级混凝土的力学参数。结果表明，10% 的石灰污泥比普通混凝土性能更好。这项研究表明，石灰污泥可以作为独特的额外胶凝物质应用到特定比例的混凝土中。
