摘要
The present invention provides concrete having improved plastic shrinkage crack resistance, comprising: concrete; and non-alkaline resistant glass fibers. In one embodiment of the invention, the non-alkaline resistant glass fibers are E-glass fibers that comprise at least 0.025 percent by volume of the concrete, and the fibers have lengths ranging from 1.27 cm to 5.08 cm and diameters rang ing from 5 micrometers to 23 micrometers. The present invention also provides a method of reducing plastic shrinkage cracks in concrete, comprising the steps of: combining cement, aggregate, sand and water to form concrete; adding a desired amount of non-alkaline resistant glass fibers to the concrete; and mixing the concrete and glass fibers to disperse the glass fibers uniformly throughout the concrete, wherein the glass fibers reduce the amount of plastic shrinkage cracks of the concrete as compared to non-fiber reinforced concrete.
