Experience with new type of compressed-air concrete placing equipment at Dam No. 5 on Upper Mississippi River; concrete having slump of only 1 1/2 in. is pumped through pipes 7 in. in diam for distances of nearly 1000 ft, even at temperature of 10 F below zero; concrete is vibrated in forms by aid of electrically driven devices inserted into mass; automatic devices; clearing of pipe.
