EVALUATION OF CARBONATED PRODUCT FROM MINERAL CARBONATION OF MINING WASTE FOR CARBON SEQUESTRATION Umi Rukiah Abdullah, Faradiella Mohd Kusin, Wan Azlina Wan Ab Karim Ghani Planning Malaysia, 2024 Mining operations generate significant quantities of waste containing alkaline earth silicates, which are valuable for carbon sequestration. Hence, the goal of this study is to assess the possibility of using mining waste to store carbon through a process of mineral carbonation. The study tested mineral carbonation under low reactivity conditions, including ambient pressure and low temperature, to evaluate the effect of pH levels on process efficiency. The samples were discovered to have an alkaline pH, suggesting that they were suitable for mineral carbonation reactions from the beginning. The carbonation process of the mineral was conducted at different pH levels of 8, 10, and 12. The findings showed that the carbonation efficiency was approximately 3%, with the highest level observed at pH 12. Through thermogravimetric analysis, it was observed that there was a multi stage transformation of minerals, which indicated the formation of carbonates containing iron and magnesium. The process captured approximately 33 and 39 g of CO2/kg. The process indicates that mine waste can be used as a source material for mineral carbonation, as demonstrated by the formation of iron and calcium carbonate products. This research demonstrates that mine waste has the potential for long-term carbon storage, offering a beneficial method for waste management and carbon capture strategies.
Marble Waste Utilization in Geopolymerized Concrete Incorporating Outdoor Heat Exposure and Alkali Activated Material , Mohamad Adib Aiman Mohd Montare, Muhammad Amir Aizat Khamis, , Umi Rukiah Abdullah, , Faradiella Mohd Kusin, and International Journal of Integrated Engineering, 2024 Marble waste can be incorporated in the geopolymerized concrete production as supplementary cementitious material.Therefore, this study intends to assess physical and mechanical properties of a geopolymerized product through marble waste utilization under outdoor heat exposure (OHE) and use of alkali activated material (AAM).In concrete production, marble waste was used at 20% by ratio and the specimen was subjected to OHE of 3-5 days and AAM/cement ratio of 0.3-0.4.Compressive strength analysis was performed to evaluate performance of geopolymerized concrete under the influence of OHE and AAM.The mineralogical and microstructure composition of the geopolymerized concrete were determined using XRD and SEM analysis, respectively.On average, specimens with 0.3-0.4AAM/cement ratio and 3-5 days heat period have shown higher compressive strength than the control.The XRD and SEM analyses showed that the production of calcium silicate hydrate and other cementitious compounds were formed in the geopolymerized concrete product.Therefore, marble waste can be regarded as a suitable material to be used as supplementary cementitious material incorporating alkali activated material and outdoor heat exposure.This is in line with the concept of waste restoration in construction material for long-term environmental sustainability.
