CACs are commonly known to have higher thermo-durability properties but have previously been observed to experience a major strength 网页Grouting increased the stiffness and reduces the hydraulic conductivity of the sands. The shear-strength behavior of the grouted sands was described satisfactorily by the Mohr-Coulomb failure criterion. The bleed capacity of the injected suspensions was a good indicator of the grouting-induced mechanical and hydraulic behavior improvement. 网页Geopolymer is widely used as a supplement to cementitious composites because of its advantages of low carbon and environmental protection, and geopolymer concrete is also broadly used in practical engineering. In recent years, geopolymer concrete has attracted increasing interest owing to its superior mechanical properties, and a series of research 网页2023年1月1日 @article{Ehsani2023ThePE, title={The positive effects of power ultrasound on Portland cement pastes and mortars; a study of chemical shrinkage and mechanical performance}, author={Ahmad Ehsani and Eshmaiel Ganjian and Olivier Haas and Mark Tyrer and Timothy J.
