“…For the creation of fresh concrete, the constituent elements were properly mixed, and then the needed amount of water was added. Throughout the mixing procedure, a 12 (0.5) water to cement ratio was used (Ponnada et al 2020). (BS EN 12350-2:2019) to confirm the uniformity of the concrete mixtures.…”

“…With around 60% replacement, the strength qualities were improved. Ponnada et al (2020) studied the strength and workability of concrete containing fine aggregates of untreated sea sand and quarry dust. For 50% untreated sea sand and 50 percent quarry dust, the best concrete mixture was obtained.…”

“…It was found that the flexural strength of concrete with 25% and 100% quarry dust were, respectively, 2% and 4.3% higher compared with ordinary concrete. In addition, the optimum CRD replacement level for strength properties of concrete was 20% (Febin et al, 2019;Kumar & Ram, 2018;Ponnada et al, 2020).…”

Concrete industry is challenged by sustainability and technical concerns. Sustainability includes minimization of raw material usage, energy consumption, and emission of greenhouse gases, while technical concerns comprise the enhancement of mechanical properties and durability such as compressive strength, resistance to chloride, acids, and elevated temperatures. Therefore, recycling of industrial waste in manufacturing of green concrete has become a robust viable alternative to disposal, due to the limited natural resources and raw materials which contribute to sustainable construction. Consequently, this research aims to develop an approach using a multicriteria decision-making algorithm based on Analytical Hierarchy Process (AHP), to select the most suitable industrial waste to achieve the desired green concrete properties. The research starts by determining the alternatives including 18 industrial wastes, and the criteria including 14 properties of concrete. After that, an experimental database for the influence of the alternatives on the criteria is established based on the literature. Then, an algorithm is developed using a python script to analyze the influence of incorporating each of the industrial waste alternative on both the mechanical and sustainable properties of concrete. Subsequently, the efficiency of the proposed algorithm is validated using three case studies that present different circumstances of concrete specifications. Based on the proposed approach, the decision-maker can assign the appropriate residual waste to be incorporated into the concrete mix according to its application in a user-friendly manner. Such approach can support both sustainable use of waste materials and enhancement of concrete properties.

“…Even the corrosive rate was decreased for geopolymer-reinforced concrete with sea sand. Untreated sea sand can be utilized in CC to reduce the use of natural river sand [33,34]. The results of various studies have indicated that the CC with crushed limestone has shown improved mechanical and rheological properties [35].…”

The aim of this research was to find the best alternative for river sand in concrete. In both geopolymer concrete (GPC) and cement concrete (CC), the fine aggregates are replaced with various sustainable mineral ashes, and mechanical and durability tests are conducted. Specimens for tests were made of M40 grade GPC and CC, with five different soil types as river sand substitute. The materials chosen to replace the river sand are manufactured sand (M-sand), sea sand, copper slag, quarry dust, and limestone sand as 25%, 50%, 75%, and 100%, respectively by weight. GPF50 and CC50 were kept as control mixes for GPC and CC, respectively. The test results of respective concretes are compared with the control mix results. From compressive strength results, M-sand as a fine aggregate had an increase in strength in every replacement level of GPC and CC. Additionally, copper slag is identified with a significant strength reduction in GPC and CC after 25% replacement. Copper slag, quarry dust, and limestone sand in GPC and CC resulted in considerable loss of strength in all replacement levels except for 25% replacement. The cost of GPC and CC is mixed with the selected fine aggregate replacement materials which arrived. Durability and cost analyses are performed for the advisable mixes and control mixes to have a comparison. Durability tests, namely, water absorption and acid tests and water permeability and thermal tests are conducted and discussed. Durability results also indicate a positive signal to mixes with M-sand. The advisable replacement of river sand with each alternative is discussed.
