摘要
自密实轻质混凝土材料具有免振捣和自重小的优点,符合当前绿色可持续发展的理念,并满足对新型建筑材料的高要求,但该材料具有性脆、收缩性大等缺点。为改善其性能,本文采用单一变量法制备自密实轻质混凝土,通过掺入不同类型的纤维材料,制备成纤维增强型混凝土材料,并对其力学性能以及干缩性能进行相关的研究,为以后同类研究奠定了较好的基础。
Self-compacting lightweight concrete,a material with the advantages of vibration-free compaction and low self-weight,aligns with the current concept of green and sustainable development,and meets the high requirements for new building materials.However,the material has disadvantages such as brittleness and high shrinkage.In order to improve its performance,this paper employs a single variable method to prepare self-compacting lightweight concrete.By incorporating different types of fiber materials,fiber-reinforced concrete is produced,and its mechanical properties and dry shrinkage properties are studied,which has laid a solid foundation for future research.
