LOW-COST CONCRETE FINDS A NEW USE

The construction is described of the small dam, Marmot Dam near Portland, Oregon, which demonstrates the feasibility of establishing the quality control necessary to replace a small dam with a leak-proof, fast-tracked roller-compacted concrete (RCC) structure. After demolishing the old dam, the exposed foundation rock was covered with 1/2-in of cement-rich, high-slump bedding mortar to fill fine cracks and open joints. Highlights of the controlled placement are briefly described. The operations were made as simple as possible so that workmen could perform with very little instruction. Latest developments in RCC technology will promote its use in the rehabilitation and replacement of existing dams. When site access is difficult, foundation conditions are appropriate and fast track construction is paramount, RCC merits consideration.
