THE WATER-DEMAND AND GAP-VOLUME OF AGGREGATE FOR FERROCEMENT

Abstract

In designing concrete based on paste saturation we should know the water-demand of cement, aggregate and the Gap-volume of aggregate mixture. The water-demand assures the consistency of fresh concrete and the cement-setting. The paste saturated concrete can be designed if the Gap-volume of aggregate is known. The experimental results of the author in this investigation shows such analytical relationships from which the water-demand and the Gap-volume of aggregate can easily be determined for the case of the gradually and continuously graded aggregates with maximal particle size (D = 1:2:4 mm).
