Comparing common methods of assessing pozzolanic reactivity assessment of pozzolanic reactivity for grinding spent bleaching earth ash (SBEA)

In order to reduce greenhouse gas emissions due to natural anaerobic degradation, SBE was used as a cement substituent on concrete, in addition, helping in improving the quality of the concrete formed. The significance of this study is to learn about the performance of SBEA in compressive strength,...

Mechanics of materials In order to reduce greenhouse gas emissions due to natural anaerobic degradation, SBE was used as a cement substituent on concrete, in addition, helping in improving the quality of the concrete formed. The significance of this study is to learn about the performance of SBEA in compressive strength, chemical, and physical properties. Besides that, this study was using SBEA as the waste material is becoming useful and makes benefits to the construction industry for a better and greener environment. To determine the potential of pozzolanic reactivity of SBEA in concrete, strength activity index (SAI), Chapelle test, and X-ray diffraction, (XRD) was carried out. In this project, the main objective is to determine the reactivity of untreated and ground SBEA using SAI, XRD, and Chapelle tests then compare the overall result of the tests. From the XRD test, Quartz is found as the main component in SBEA sample. Furthermore, the SAI value for untreated SBEA mortar, 120 and 240 minutes of ground SBEA mortar at later age is higher than the early age. Futhermore, in Chapelle test, the 240 minutes ground SBEA exhibits highest pozzolanic activity which is 911 mgCa(OH)2/g while the untreated SBEA exhibits lowest pozzolanic activity which is 146 mgCa(OH)2/g. This is due to the difference grinding time affect the particles size of pozzolan. The higher the total surface area of the pozzolan, the higher the pozzolanic reactivity. Therefore, SBEA is proved to exhibit high pozzolanic reactivity. 2022 Academic Exercise NonPeerReviewed text en https://eprints.ums.edu.my/id/eprint/35260/1/24%20PAGES.pdf text en https://eprints.ums.edu.my/id/eprint/35260/2/FULLTEXT.pdf Chea Wan Chin (2022) Comparing common methods of assessing pozzolanic reactivity assessment of pozzolanic reactivity for grinding spent bleaching earth ash (SBEA).
