摘要
混凝土作为应用最广泛的建筑材料,因其脆性较大在使用的过程中极易开裂,对混凝土在使用过程中的力学性能与耐久性能产生不利影响。高延性水泥基复合材料因具有极佳的延展性而被广泛应用在实际工程中,具有良好的发展前景。传统高延性水泥基复合材料的造价成本较高,因此有必要寻找一些新的原材料替代原有材料,以降低制备成本。该文首先介绍了高延性水泥基材料的典型力学性能,然后说明了可以用于制备高延性水泥基复合材料的原材料选择,最后阐述了高延性水泥基材料在实际工程中的应用,并对未来的研究方向作出展望。
Concrete,as the most widely used building material,has an adverse impact on the mechanical properties and durability due to its brittleness in the process of use.High-ductile cementitious composites(HDCC) are widely used in practical engineering and have good prospects for development because of their excellent ductility.The cost of traditional HDCC is high,so it is necessary to find some other raw materials to replace the original ones and reduce the preparation cost.Therefore,this paper first introduces the typical mechanical properties of HDCC,thereafter,the selection of raw materials that can be used to prepare HDCC,and finally,the application of HDCC in practical engineering,while giving an outlook on the future research directions.
