摘要

本研究涉及通过生物质热解获得的纳米/微粒的使用。将 Camara(植物)转化为生物炭,并通过球磨进一步将其减小到纳米/微米大小。生物炭是在 550°C 的惰性环境下热解产生的。生物炭以水泥重量的 0%、0.05% 和 0.1% 的比例添加到水泥混合砂浆中。对早期龄期特性进行了检测,并与对照试样进行了比较。结果显示,密度、抗压强度和稠度降低,凝结时间和抗折强度增加。由此得出结论,添加 Camara 的生物炭可以提高水泥砂浆在某些参数上的性能。因此,通过添加废弃植物的生物炭,可以生产出绿色环保、性能更高的水泥基产品。这也将增加全球关注的碳封存。

Lantana Camara Plant-Biochar Added Cementitious Mortar for Carbon Sequestration: Effect on Early-Age Properties
Present study deals with the use of nano/micro sized particles acquired through pyrolysis of biomass. Lantana Camara (plant) was transformed into Biochar, which was further reduced to nano/micro size by ball milling. Biochar was produced by pyrolysis at 550°C in an inert environment. The biochar was added to cementitious mortar mixes in quantities of 0, 0.05, and 0.1% by weight of cement. Early age properties were examined and compared with those of the control specimens. The results showed reduction in density, compressive strength and consistency and an increase in setting time, and flexural strength. It is concluded that the addition of the biochar of Lantana Camara enhances the performance of the cementitious mortars in some parameters. Hence, green, and more performing cementitious products can be manufactured by adding the biochar of the waste plant. This will also add to Carbon sequestration, which is a global point of concern.
