摘要

在建筑领域,混凝土是不可或缺的。非结构性用途占混凝土生产的很大一部分。发泡混凝土(FC)具有惊人的多孔性,随着空隙数量的增加,材料的热特性也会降低。由于这些用途需要大量混凝土,对它们进行研究可能会为优化混凝土的材料效率和更好地利用其废品提供有用的信息。FC 具有优异的压缩性能,但由于会产生多条微裂缝,因此拉伸性能较差。如果没有额外的加固元件,FC 无法承受外力引起的拉伸应力。因此,本研究调查了基于聚丙烯(PP)纤维的泡沫混凝土的机械性能。研究中使用了水泥、粉煤灰、硅灰和聚丙烯纤维等有效材料。本研究提出了一种用于设计和预测泡沫混凝土强度的新发明,并在 python 的帮助下确定了纤维增强泡沫混凝土的抗压强度、劈裂拉伸强度和抗折强度等强度性能,还确定了抗压强度的实验值和预测值。研究结果清楚地表明,可以有效利用粉煤灰和硅灰制造轻质产品,从而提高印度等发展中国家青年的盈利能力、可持续发展能力和创业能力。

Study on the Performance Behaviour of Fibre Reinfored Foam Concrete
In the construction sector, concrete is indispensable. Non-structural uses account for a significant portion of concrete production. Foamed concrete (FC) is incredibly porous, and as the number of voids increases, the material's thermal characteristics decrease. Since these uses need a substantial amount of concrete, researching them might yield useful information for optimizing concrete's material efficiency and making better use of its waste products. FC is excellent in compression but poor in tension because it creates multiple microcracks. FC cannot withstand the tensile stress induced by the applied forces without additional reinforcement elements. Hence, this research investigates the mechanical properties of polypropylene (PP) fibers based foam concrete. The utilization of effective materials such as cement, flyash, silica fume and PP fibre were used in this investigation. In this study, a novel invention is proposed for designing and strength prediction of foam concrete and find out the strength properties such as compressive strength, split tensile strength and flexural strength of fibre reinforced foam concrete were determined and the experimental and predictive value of compressive strength were also determined with the help of python. The results provide a clear idea of ​​the efficient use of fly ash and silica fume for the manufacture of light weight based products that promote profitability, sustainability and entrepreneurship for youth in developing countries such as India, and it is important by conserving natural resources through savings in the consumption of cement and aggregates.
