Self-stress desert sand ultrahigh-ductility concrete and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to self-stress desert sand ultra-high ductility concrete and a preparation method thereof, solves the problem of high shrinkage caused by application of desert sand in ultra-high ductility concrete UHDC, and at the same time, under the principle of referring to the micromechanical strength criterion and the energy criterion during ECC mix proportion design, the self-stress desert sand ultra-high ductility concrete is obtained. Through fiber selection, matrix strength design and fiber and matrix interface bonding performance design, the UHDC has excellent deformability and multi-microcrack cracking characteristics. The self-stress desert sand ultrahigh-ductility concrete has the characteristics of self stress, high ductility, environmental protection and the like, and is suitable for the fields of structure repair and reinforcement, bridge pavement prefabrication and splicing, automatic construction and the like.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种自应力沙漠砂超高延性混凝土及其制备方法，本发明解决了沙漠砂在超高延性混凝土UHDC中应用导致的高收缩问题，同时在借鉴ECC配合比设计时的微观力学强度准则和能量准则的原则下，通过纤维选择、基体强度设计、纤维与基体界面粘结性能设计使UHDC具有优异的变形能力和多微裂缝开裂特征。本发明的自应力沙漠砂超高延性混凝土具有自应力、高延性、绿色环保等特性，适用于结构修复加固、桥道面预制拼接以及自动化建造等领域。
