Comparative Experiment on Frost Resistance of Different Kinds of Polymer Fibrous Concrete
Based on the evaluation of fibrous concrete materials and the experiments of freezing-thawing resistance home and abroad, the present experiment takes relative dynamic modulus of elasticity and rate of mass reduction as an analytical index to conduct a comparative study on the effects of the mixing of four kinds of polypropylene fiber on the cement concrete freezing resistance. The results show that different kinds of polypropylene fiber have different influences on cement concrete freezing resistance. And some polypropylene can improve it while others may make it decreased.
