Abstract: Certain salts of calcium and magnesium can mitigate alkali-silica reaction (ASR) by reducing the pH of concrete pore solution. In a previous study, eight such promising salts were identified out of more than 700 possible ...

Abstract: Recent interest in creating green construction materials has sparked the development of portland cement–free binders. Alkali-activated slag (AAS) concrete has a low embodied energy and comparable or superior strengths to ...

Abstract: Application of crushed recycled glass in concrete materials can offer significant economical and environmental benefits provided that the alkali-silica reaction (ASR) of glass in concrete is properly controlled. Previous ...

Abstract: This paper investigates the use of glass cullet as a 100% sand replacement in Portland cement concrete (glasscrete) systems. Specifically, this paper evaluates the fresh and hardened properties of these systems in comparison ...

Abstract: This study compares the cradle-to-gate greenhouse gas emissions (GHGs), energy use, water use, and potential environmental toxicity of conventional (Conv), glass powder (GP), and alkali-activated slag (AAS) concrete and ...

Abstract: Partial replacement of portland cement with supplementary cementitious materials (SCMs), such as fly ash, is an effective strategy for improving durability and reducing the CO2 footprint of concrete. However, using high-volume ...

Abstract: This paper discusses the interpretation of electrical conductivity measurements in concrete to assess water penetration. Specifically, a series of finite element simulations were performed to develop an analytical function ...

Abstract: Supplementary cementitious materials (SCMs) are beneficial for improving concrete’s long-term performance, durability, and environmental impact. Impure clay sources are abundant and when calcined, may serve as suitable ...
