A Comparative Study on the Effect of Fiber on the Mechanical Properties of Novel Geopolymer Concrete Using Calcium Carbide Residue
摘要
The performance of sustainable cementless alkali-activated concrete (AAC) manufactured from industrial wastes was compared with ordinary Portland cement (OPC) concrete incorporating polypropylene fibers. It was observed that the incorporation of fibers improved flexural strength of AAC by 24% at the same fiber dosage. But the splitting tensile value and modulus of elasticity of AAC mixes were lower than that of OPC by 6.8% and 18% at 0.75% fiber dosage respectively.
