ELASTIC MODULUS OF SIFCON IN TENSION AND COMPRESSION

A graphical evaluation of various analytical models predicting the modulus of elasticity of fiber reinforced composites is first presented. Upper and lower bound solutions and their applicability to fiber reinforced concrete and slurry-infiltrated fiber concrete (SIFCON) are discussed. An experimental investigation of the elastic modulus of SIFCON in tension and compression is then described. Two different types of fibers, two different aspect ratios, seven different levels of volume fractions, and 4 different matirix compositions were used. The value of the modulus of elasticity is found to be dependent upon not only the peak compressive strength, but also factors such as fiber volume fraction, fiber aspect ratio, fiber orientation and alignment, and testing procedure. Experimental data are analyzed and conclusions are drawn.
