UNIFORMITY ASSESSMENT OF CARBON FIBRES DISPERSION IN CEMENT PASTE BY IMPEDANCE MEASUREMENTS
摘要
An alternating current was applied to measure the impedance of a hardened cement paste with various contents of carbon fibres. When the free water content in the hardened cement paste is 90%-98%, and the measuring frequency 500Hz, an approximate linear relationship was found between fibre content and impedance of the composite. Based on this relationship , a new attempt was made to evaluate the dispersion uniformity of carbon fibres in cement paste by impedance measurement. The standard deviation S and the coefficient of vriation S/Xi
