Abstract

A study was conducted to explore the effect of palm oil boiler ash (POBA) on foamed concrete by varying the percentage of POBA over sand quantities (0, 4, 8 and 12%). This paper primarily discusses the water absorption test, uniaxial compressive strength, and dry density findings. It indicates that substituting sand with POBA greatly enhances the strength of foamed concrete. When the quantity of POBA was raised up to 12% throughout all curing times, the compressive strength steadily increased in the range of 4.34–13.50 N·mm–2. Furthermore, the dry density of foamed concrete was shown to be directly related to the fraction of POBA in the mixture. The dry density of foamed concrete increases as the amount of POBA increases. Despite this, water absorption shown that increasing POBA increases water absorption percentage in foamed concrete from 7.4 to 10.4%. This is due to the fact that a composition with a high POBA percentage will generate more pores than a mixture with a low POBA percentage.

棕榈油锅炉灰（POBA）部分替代泡沫混凝土中砂的可行性研究

研究了棕榈油锅炉灰（POBA）对泡沫混凝土的影响，通过改变POBA相对于砂量（0%、4%、8%和12%）的百分比来进行。本文主要讨论了吸水性试验、单轴抗压强度和干密度的结果。结果表明，用POBA代替砂可以大大提高泡沫混凝土的强度。当POBA的用量在所有固化时间内提高到12%时，抗压强度在4.34–13.50 N·mm–2范围内稳步增加。此外，泡沫混凝土的干密度与混合物中POBA的含量直接相关。泡沫混凝土的干密度随着POBA用量的增加而增加。尽管如此，吸水率表明，增加POBA可将泡沫混凝土的吸水率从7.4%提高到10.4%。这是因为具有高POBA百分比的组合物将比具有低POBA百分比混合物产生更多的孔隙。

期刊介绍： Scientific Review Engineering and Environmental Sciences [Przegląd Naukowy Inżynieria i Kształtowanie Środowiska] covers broad area of knowledge and practice on fields such as: sustainable development, landscaping of non-urbanized lands, environmental engineering, construction projects engineering land management, protection and land reclamation, environmental impact of investments, ecology, hydrology and water management, ground-water monitoring and restoration, geotechnical engineering, meteorology and connecting subjects. Authors are welcome to submit theoretical and practice-oriented papers containing detailed case studies within above mentioned disciplines. However, theoretical papers should contain part with practical application of the theory presented. Papers (in Polish or English languages) are accepted for publication after obtaining positive opinions of two reviewers. Papers published elsewhere are not accepted.
