Abstract:Intended as a supplement to ACI 318-56, this report highlights design and construction practices pcculiar to thin-section reinforced concrete elements. High-early-strength concrete or accelerated curing is advised. Special grading limits for coarse aggregate are suggested, and specifications for steel and ad-mixtures are noted. Concrete of 3750 psi strength is recommended for protected Iocations not in contact with the ground; 5000-psi concrete is rccommended for other locations. Limits for air content, W/C ratio, and cement content are proposed. Report suggests allowable design stresses, and emphasies accurate placing of and sufficient cover for reinforcement. Fabriation is covered in provisions on mixing, molds, casting, curing, surface treatment, and tolerances of individual elements. Supervision and inspection during fabrication are stresscd, with some suggested standards of acceptance. Method and sequence of erection are also treated, including connection devices, assembly tolerances, and waterproofing of joints.
