THE EFFECTS OF HIGH FINES ON THE PROPERTIES OF CEMENT MORTAR AND CONCRETE

The use of manufactured fine aggregate (MFA) in portland cement concrete is becoming more common as sources of natural sands are being depleted. There is a strong need to better utilize MFA particularly the minus 75 micro m sizes. The development of specifications that aid aggregate producers, engineers and specifying agencies in the utilization of MFA is of interest to all parties. Better utilization of crushed aggregates has both economic and environmental benefits for the construction and materials industry. This report presents some of the effects of high fines on the properties of cement mortar and concrete. A total of 50 sands were used in the mortar study, 10 of which were included in the concrete research. A summary of the aggregate characteristics that affect the properties of mortar and concrete are presented, along with the correlations evaluated between these properties.
