New Breed of Cement-based Composites

Abstract

Recent advances in processing techniques and improved material performance have led to the emergence of a new breed of high-performance cement-based materials. Although small amount of fibers (< 1%) have been successfully used in bulk concrete construction to overcome brittleness of cement, new processing techniques have helped in the manufacture of thin-sheet products with as high as 15% vol of continuous and discontinuous fibers. Fibers in such large quantities fundamentally alter the nature of the cement-based matrix, and the inherent tensile strength and strain capacity of the matrix itself are greatly enhanced. New applications as replacement for energy intensive plastics and metals are now not only feasible but attractive.
