Mechanical Properties of Ductile Cementitious Composites Incorporating Microencapsulated Phase Changns have been proposed, mainly utilizing fibres. One of the most promising classes of materials is strain hardening cementitious composite (SHCC). It utilizes PVA fibres, and it relatively costly compared to regular concrete, so it is commonly used only in surface layers. This paper presents a multi-作者: choleretic 時(shí)間: 2025-3-29 07:13
A Comparative Study on Deflection-Hardening Behavior of Ductile Alkali-Activated Compositeovide high potential for waste reutilization. Alkali activated materials (AAMs) generally exhibit better durability and comparable or superior mechanical performance in comparison to traditional cementitious materials. However, like cementitious binders, AAMs are inherently brittle (quasi brittle). 作者: Inflamed 時(shí)間: 2025-3-29 13:33 作者: cultivated 時(shí)間: 2025-3-29 16:35
