At present, there are no standard testing methods to characterize plastic shrinkage cracking in plain and fibre reinforced concretes. Various specimen geometries have been used in the past to simulate a realistic condition of plastic shrinkage cracking. This includes slabs with stress concentrators, rings, a modified beam test and slabs with realistic substructures . Some of the measurement techniques reported in the above tests use randomly selected locations over a large cracked surface to assess the cracking potential. In addition, conducting accurate manual measurement of the entire cracked area is rather complex and cumbersome. The crack measurements reported also involve cumbersome calculations, and the use of average crack width at selected locations sometimes leads to erroneous interpretation. Image analysis of the cracked area is reported to be more appropriate than manual crack measurement to study cracking at different scales. With the use of image analysis, it has become easier to monitor the crack development and microstructure of cementitious systems.
In this paper, an attempt has been made to study the synergistic behavior of hybrid combinations of steel and non-metallic fibres in controlling plastic shrinkage cracks.

目前,有没有标准的测试方法的特点塑性收缩裂缝在平原和纤维增强混凝土。各种几何形状的标本已过去所使用的模拟现实条件的塑性收缩裂缝。这包括地砖与应力选矿厂,戒指,改良束测试和砖与现实子。一些测量技术报镇高枣告,在上述的测试中使用随机挑选的地点超过一个大破获表面,以评估打击的潜力。此外,进行准确的手工测量御拆的整个破获面积是相当复杂和烦琐。裂纹测念空量报告还涉及繁复的计算,以及使用的平均裂缝宽度在选定的地点,有时会导致错误解释。图像分析该地区破获据报道,较为恰当比手册裂纹测量,研究打击在不同级别上。与利用图像分析,它已成为更容易监察裂纹的发展和显微结构的胶凝系统。
在这方面的文件,已试图研究的协同行为的杂交稻组合钢及非金属纤维在控制塑性收缩裂缝。
