The American Concrete Institute announces the availability of six new publications:
117-06: Specifications for Tolerances for Concrete Construction and Materials and Commentary — This document specifies standard tolerances for concrete construction. It is intended to be used as the reference document for establishing tolerances for concrete construction by specification writers and ACI committees.
234R-06: Guide for the Use of Silica Fume in Concrete — This report describes the physical and chemical properties of silica fume, how silica fume interacts with portland cement, the effects of silica fume on the properties of fresh and hardened concrete, recent typical applications of silica-fume concrete, how silica-fume concrete is proportioned, specified, and handled in the field, and areas where additional research is needed.
360R-06: Design of Slabs-on-Ground — The report addresses the planning, design, and detailing of slabs-onground, primarily industrial floors. Background information on design theories is followed by discussion of types of slabs, soil-support systems, loadings, and jointing. Design methods are given for unreinforced concrete, reinforced concrete, shrinkage-compensating concrete, post-tensioned concrete, fiber- reinforced concrete slabs-on-ground, and slabs-on-ground in refrigerated buildings, followed by information on shrinkage and curling problems.
522R-06: Pervious Concrete — This report provides technical information on pervious concrete, including application, design methods, materials, properties, mixture proportioning, construction methods, testing and inspection.
523.1R-06: Guide for Cast-in-Place Low-Density Cellular Concrete — This guide provides information on the materials, properties, design, proper handling, and applications of castin- place low-density cellular concretes having oven-dry densities of 50 pounds per cubic foot or less. Roof deck systems and geotechnical applications often incorporate these low-density cellular concretes.
ITG-4.2R-06: Materials and Quality Considerations for High-Strength Concrete in Moderate to High Seismic Applications — This document addresses materials and quality considerations when using cast-in-place, normal-weight, highstrength concrete in structures that must be designed for moderate to high seismic applications.
