Abstract:
Volume change due to variations of humidity will result in tensile stress and lead to cracking of concrete. Because of the growing interest in predicting the tensile shrinkage stresses that give rise to cracking of concrete and the increasing use of fiber reinforced concrete, this research investigated the factors that influence shrinkage of fiber reinforced concrete. Shrinkage data are reported with parameters including specimen size, fiber type, fiber content, and age of concrete drying starts. The test results indicate that optimum volume content of fibers to reduce shrinkage of concrete is less than 2 percent, and that shrinkage is comparably less for concrete containing fibers with larger aspect ratios.
