Review of Recent Developments Regarding the Durability Performance of Eco-Friendly Geopolymer Concrete

Abstract

The 21st century has witnessed a substantial increase in the demand for construction materials, mainly influenced by the growing population. This increase in demand has resulted in higher prices for these materials and has also placed considerable burdens on environmental resources, prompting the search for eco-friendly and economically viable alternatives such as geopolymer materials to replace traditional materials like cement. The benefits of geopolymer materials as substitutes for cement in concrete extend beyond their exceptional durability. Initially, geopolymer was introduced to address the environmental impact arising from carbon dioxide emissions and the substantial consumption of fossil fuels through the production of cement. The current review investigates recent advances regarding the durability characteristics of geopolymer materials. This includes aspects such as water absorption, temperature resistance, sulfuric acid resistance, sulfate resistance, chloride ion penetration, and freeze–thaw resistance, among others. The results of this review highlight geopolymer concrete’s enhanced durability over traditional cement-based concrete. Furthermore, this review offers recommendations and outlines potential research avenues for further exploration of geopolymer concrete.

Impact of Alkaline Concentration on the Mechanical Properties of Geopolymer Concrete Made up of Fly Ash and Sugarcane Bagasse Ash

“…Because of increased urbanization and industrialization, there is increased demand for extensive infrastructural development, requiring more concrete as a construction material. In 2021, cement production reportedly reached 4.4 billion tons worldwide [1,2], and the annual concrete consumption is forecasted to pass 18 billion tons by 2050 [3]. The manufacture of Portland cement (PC) used in concrete has substantial effects on the environment in terms of high energy use, natural resource depletion, and carbon dioxide (CO 2 ) emissions [4][5][6].…”

Development of sustainable interlocking concrete paving blocks using bamboo leaf ash and metakaolin

“…Another research focused on the application of Cu slag as a fine aggregate in concrete [ 38 ]. Alahmari et al [ 39 ] conducted a review of recent developments regarding the durability performance of eco-friendly geopolymer concrete. Other research involving the application of agro-wastes as partial replacements in concrete have been studied with important results worthy of note for further extensive experimentation [ [40] , [41] , [42] , [43] , [44] ].…”

Assessment of CO2 Capture in FA/GGBS-Blended Cement Systems: From Cement Paste to Commercial Products

“…In traditional practices, carbonation poses a risk to reinforced concrete by lowering the pH of the matrix, leading to potential corrosion of the reinforcement bars [7,8]. Nevertheless, this effect is limited to reinforced concrete with steel bars, while plain concrete or concrete reinforced with polymers or non-steel bars remains unaffected by this carbonation-induced Buildings 2024, 14, 154 2 of 16 corrosion [9].…”
