Mechanical Properties Enhancement and Mechanism of Eco-friendly Concrete Utilized by Full Aeolian Sand through a Robust Organic-Inorganic Network

Abstract

AbstractThe overexploitation of natural sands has become a pressing issue that must be addressed urgently. Aeolian sand (AS) has drawn great attention as a promising alternative material. However, their concentrated gradation, small particle size, and ...Graphical abstract showing the structure and performance of HPEI-modified aeolian sand concrete.
