Vibration has already done much to improve the quality of mass concrete. It has completely changed our concept of what is practical and desirable as a mass-concrete mix. Together with air entrainment it has made mixes of very low cement content placable with reductions in unit water content up to 80 lb percu yd. O ther improvements in quality or in cost, or both, can result when full advantage of vibration is taken to place mixes with larger aggregate in many cases where there is reinforcing, to place concrete in thicker layers, to permit useof larger buckets, and to eliminate poor bond at cold joints.
