摘　　要：研究了石粉和碳纤维对混凝土的抗压强度及耐磨性的影响。研究表明:石粉掺量低于20%,会提高混凝土的强度,石粉掺量大于20%,混凝土强度有所降低;石粉掺量为10%,可显著提高混凝土的耐磨性;碳纤维改性石粉混凝土的抗压强度高于空白混凝土,但低于掺10%石粉的混凝土;碳纤维改性石粉混凝土的耐磨性明显高于空白混凝土和单掺10%石粉的混凝土。石粉掺量为10%的石粉混凝土和碳纤维改性石粉混凝土可用于磨损环境中的混凝土工程。The influence of limestone powder and carbon fiber on the compressive strength and wear resistance of concrete were investigated. The results show that the strengths of the concrete increase when limestone powder dosage is below 20%, whereas it is opposite when limestone powder dosage exceeds 20%. The wear resistance of concrete can be dramaticall~ improved when introducing 10% limestone powder. The carbon fiber concrete has higher compressive strengths than the blank concrete, but it is below than the 10% limestone powder concrete. Whereas for wear resistance, the carbon fiber concrete demonstrate super performances than both the blank concrete and the 10% limestone powder concrete. Both the carbon fiber concrete and limestone powder concretes can be implied in wear condition.
