The Ready Mixed Concrete Industry LEED Reference Guide

Of all the green building design and construction evaluation programs in the Unites States, the United States Green Building Council’s (USGBC) LEED Rating System is the most widely adopted standard. Public and private companies, government agencies, trade groups, and other entities throughout the United States construction industry have adopted LEED as the standard for determining a building’s degree of sustainability. Recognizing the importance of LEED, NRMCA, PCA, and the RMC Research Foundation commissioned the
development of a LEED Reference Guide that could be used by architects, developers, clients, builders, manufacturers, suppliers, and others in the construction industry to determine how the use of ready mixed concrete can contribute to sustainable building.
The resulting document presents a detailed discussion of the LEED program, how LEED points are assigned, how material uses and construction methods must be documented, and what issues must be carefully considered in using ready mixed concrete to enhance a building’s sustainability.
Potential LEED points gained through the use of ready mixed concrete are discussed in the following areas: stormwater management; landscape paving; minimizing energy use; optimizing energy performance; managing construction waste; recycled content; use of regional materials; use of certified wood; innovation in design; site-wide VOC reduction; and reduction in the use of portland cement. The document also covers plant waste water disposal; on-site wash water disposal; solid waste; and site protection. In each of these areas, the Reference Guide presents information useful to the designer, the contractor, and the ready mixed concrete supplier in achieving LEED points. This information is supplemented by extensive lists of citations, references, and other resource documents, trade groups, and websites.

Precast concrete floor slabs

Part one of this booklet is intended as a quick and general guide to precast concrete floor slabs. In this book we will cover the features and benefits of precast concrete floor slabs, the general applications, some design guidelines, on-site considerations and some general information. Part two contains the more technical information.

Hollow-Core Slab System

Hollow-core was originally conceived and developed as South Africa’s alternative to insitu cast concrete floor panels for multi-storey buildings some 25 years ago. In today’s world of innovation and fast-tracking, the hollow-core floor slab is a viable and in many instances, preferable alternative to more conventional building methods. Besides the obvious advantages of simpler, faster construction, not to mention a more durable end product, the secret of applying the material successfully is in the pre-planning. Get one of the CMA member companies involved at the concept stage and their advice and design input comes at no charge. Set out in this manual are several examples demonstrating the versatility and multi-purpose functionality of the prestressed and reinforced hollow-core slabs. Applications covered include security walls, reservoir roofing, retaining walls and warehouse walling, multi-storey floor applications to residential, commercial and industrial buildings, as well as suspended ground floor slabs in clay areas. Also discussed are important sub-contracting aspects which apply when slabs are deployed in their more traditional guise as flooring.
