Use of e-glass fibers to reduce plastic shrinkage cracks in concrete

摘要

The present invention provides concrete having improved plastic shrinkage crack resistance, comprising: concrete; and non-alkaline resistant glass fibers. 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.
