摘　　要：为增强混凝土的早期抗裂性和提高混凝土的韧性,采用单掺钢纤维(SF)、玻璃纤维(GF)和混杂两种纤维(SF与GF)的方法试验研究了纤维混凝土的早龄期工作性,通过平板试验研究了各种掺杂纤维的早龄期抗裂效果,并对试验结果进行了分析和比较。To enhance the early age anti-cracking performance and improve the toughness of concrete, the experimental method of the single steel fiber （SF）,glass fiber （GF） and hybrid fiber of the above two fiber （SF and GF） is applied to study the early age work performance.The early age anti-crack effects of the above fiber reinforced concrete were investigated by slab test,and the experimental results of all kinds of fiber reinforced concrete were analyzed and compared with the common one.
