“…Fly ash [8][9][10] and blast furnace slag [11][12][13] are two commodities that have been successfully commercialized for construction materials and received positive feedback. Meanwhile, rice husk ash [14][15][16], bagasse ash [17][18][19], palm oil waste [20][21][22], and Kaolin [23][24][25] are among the materials being researched as alternatives for cement replacement.…”

Concrete is considered one of the construction materials that contribute the most significant carbon dioxide in the world. Meanwhile, according to various studies, concrete production will continue to rise through 2050, especially in developing countries. According to several reports, cement manufacture is one of the largest sources of carbon dioxide in the concrete sector. In addition, overexploitation of aggregates due to concrete production also causes unavoidable natural damage. Bottom ash waste was used as a replacement for cement and fine aggregate as sustainable construction materials. It is envisaged that this research would allow industrial waste to be utilized to its full potential, resulting in a concrete that is more environmentally friendly and minimizes carbon dioxide emissions during the manufacturing process. This study is divided into bottom ash as a cement substitute and bottom ash as a fine aggregate substitute. The engineering properties of the concrete were checked during the experiments in this study when it was fresh and hardened states. The slump test is used to determine the workability of fresh concrete. While for the hardened properties tests consist of compressive strength, splitting tensile strength, flexural strength, and mass density. The usage of bottom ash as a cement replacement demonstrates that as the composition of bottom ash increases, the performance of the hardened properties of concrete decreases. While using bottom ash as a fine aggregate replacement reveals that the performance of hardened properties has improved as the proportion of bottom ash utilized has increased.

“…Ensemble ML uses multiple learning algorithm to obtain better predictive performance as compared to any constituent learning algorithm alone. Therefore, individual and ensemble ML techniques have been compared in this study to identify the superlative model for predicting the hardened properties of concrete (Chou and Pham, 2013;Pouriyeh et al, 2017;Salami et al, 2021;Tantri et al, 2021aTantri et al, , 2021bTantri et al, , 2021cPrayuda et al, 2020;Prasad et al, 2021).…”

“…The concrete used for infrastructure of modern days is not restricted to only cement and aggregate. Mineral and chemical admixtures have been used extensively for better adaptability based on situational demand (Chou et al , 2011; DeRousseau et al , 2019; Kovler et al , 2000; Balendran et al , 2002; Ghanbarpour et al , 2010; Prayuda et al , 2020). Since concrete is a heterogeneous material, prediction of exact compressive strength with its influencing factors is quite complicated.…”

Purpose The compressive strength of concrete depends on many interdependent parameters; its exact prediction is not that simple because of complex processes involved in strength development. This study aims to predict the compressive strength of normal concrete and high-performance concrete using four datasets. Design/methodology/approach In this paper, five established individual Machine Learning (ML) regression models have been compared: Decision Regression Tree, Random Forest Regression, Lasso Regression, Ridge Regression and Multiple-Linear regression. Four datasets were studied, two of which are previous research datasets, and two datasets are from the sophisticated lab using five established individual ML regression models. Findings The five statistical indicators like coefficient of determination (R2), mean absolute error, root mean squared error, Nash–Sutcliffe efficiency and mean absolute percentage error have been used to compare the performance of the models. The models are further compared using statistical indicators with previous studies. Lastly, to understand the variable effect of the predictor, the sensitivity and parametric analysis were carried out to find the performance of the variable. Originality/value The findings of this paper will allow readers to understand the factors involved in identifying the machine learning models and concrete datasets. In so doing, we hope that this research advances the toolset needed to predict compressive strength.

“…Industrial wastes that are not properly disposed of have become one of the research subjects for researchers as a substitute for cement or aggregate. Among them is blast furnace slag from steel production (Kim and Lee, 2013), as well as agricultural industrial wastes, such as rice husk ash, bagasse ash and palm oil ash (Saleh et al , 2019; Sijuvorakul et al , 2011; Prayuda et al , 2020). Additionally, one of the industrial wastes that are well-known and frequently used is fly ash and bottom ash from coal-fired power plants.…”

Purpose This study aims to investigate the properties of mortar made from a bottom ash substitute as a sustainable construction material. It is believed that the use of cement in concrete construction contributes to the release of carbon dioxide into the atmosphere, which has been a consistent increase in recent years. The utilization of bottom ash waste is expected to reduce pollution associated with cement production. Design/methodology/approach Bottom ash is used as replacement materials for cement and fine aggregate in the manufacture of mortar. Bottom ash substituted for cement of 10%, 20% and 30% of the total weight of the binder, whereas bottom ash substituted for the fine aggregate of 30%, 40% and 50% of the total weight of the sand. Binder properties were determined using scanning electron microscopy and energy dispersive X-ray. Meanwhile, the fresh properties (slump flow) and hardened properties were determined (compressive strength and mass density). In the hardened properties test, two types of curing were used: water and sealed curing. Findings The compressive strength of mortar decreased as the amount of bottom ash as cement replacement. However, the compressive strength increased when bottom ash was used as aggregate replacement. Additionally, bottom ash was sufficient as a substitute for fine aggregate than as a substitute for cement. Originality/value This research presents test results that are more straightforward to apply in the construction site.
