Available in PDF, EPUB and Kindle. Book excerpt: Recent stormwater management regulations from the Environmental Protection Agency (EPA) and greater emphasis on sustainable development has increased interest in pervious pavement as a method for reducing stormwater runoff and improving stormwater quality. Pervious concrete is one of several pervious pavement systems that can be used to reduce stormwater runoff and treat stormwater on site. Pervious concrete systems have been used and are being proposed for all parts of the United States, including northern climates where severe freezing and thawing can occur. The purpose of the research is to develop pervious concrete mixtures that have sufficient porosity for stormwater infiltration along with desirable porosity, strength, and freeze-thaw durability. In this research, concrete mixtures were developed with single-sized river gravel aggregate (4.75 mm) and constant binder contents, together with high range water reducer. River sand was used as a replacement for up to 7 % coarse aggregate. Two different types of polypropylene fibers (a shorter fibrillated variable-length and a longer fibrillated single-length) were incorporated at several addition rates from 0 to 0.1 % by volume of concrete. The engineering properties of the aggregate were evaluated along with the porosity, permeability, strength, and freeze-thaw durability of selected concrete mixtures. The results indicate that the use of sand and fibers provided beneficial effects on pervious concrete properties, including increased strength, maintained or improved permeability, and enhanced freeze-thaw resistance.

This book was released on 2006 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portland cement pervious concrete (PCPC) is increasingly used in pavement applications due to its benefits in reducing the quantity of runoff water, improving stormwater quality, enhancing the skid resistance of the pavement during storm events by rapid drainage of water, and reducing pavement noise. In the United States, PCPC typically has high porosity and low strength, which has resulted in limited use of pervious concrete, particularly in hard wet freeze environment (i.e., Midwest and North East of the U.S. and other parts of the world). Improving the strength and freeze-thaw durability of pervious concrete is necessary for increasing use of PCPC in these regions. Included in the following thesis is a literature review that includes the current state-of-practice in PCPC design, construction, and related environmental issues. The purpose of this research is to develop PCPC mix proportions that have not only sufficient porosity for stormwater infiltration, but also desirable strength and freeze-thaw durability. In this research, concrete mixes were designed with various sizes and types of aggregates, binder contents, and amounts of admixtures. The engineering properties of the aggregates were evaluated. The porosity, permeability, strength, and freeze-thaw durability of these mixes were measured. Results indicate that PCPC made with single size aggregate generally has high permeability (greater than 2000 in./hr) but not adequate strength (less than 3000 psi). Addition of a small amount of sand (5% to 7%) and fiber can significantly improve strength and freeze-thaw resistance of the concrete with limited reduction in permeability. Similar to conventional concrete, there are close relationships between PCPC air void content, permeability, and compressive strength. Compaction method and energy has considerable effect on concrete uniformity and properties. Based on the results, well-designed pervious concrete can achieve the strength, permeability, and freeze-thaw resistance to allow wide-spread use in northern climates.

Available in PDF, EPUB and Kindle. Book excerpt: Concrete durability in climates where freezing and thawing occurs is a continuing problem. It is particularly acute for highway and bridge structures, where de-icing salts are used to combat the effects of frost, snow and ice. These salts can cause damage to concrete and accelerate corrosion of reinforcements. This book presents the latest international research on this area, with contributions from North America and Europe which were presented at an international RILEM workshop.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of research papers, presented at meetings organised by the Wessex Institute of Technology (WIT), concerns a variety of issues relating to the area of sustainable development. WIT has a long and very successful record of organising conferences on the topic of sustainability, which requires an interdisciplinary approach. Any sustainable solutions that are derived solely from the perspective of a single discipline may have unintended damaging consequences that create new problems. Thus effective sustainable solutions require the collaboration of scientists and engineers from various disciplines, as well as planners, architects, environmentalists, policy makers, social scientists, and economists. The contents of this book reflect that interdisciplinary approach, and include topics under the main areas of: Sustainable development and planning; Disaster management; Air pollution; Urban transport; Ecosystems and Water resources management.

Book excerpt: This study, aimed at improving the freeze-thaw resistance of concrete, consists of three parts. Part I evaluates parameters affecting the freeze-thaw durability of concrete. A modification of the existing standard of method for determining the durability factor of concrete specimens is proposed, and a new procedure for fundamental transverse frequency (used in durability factor calculations) has been developed. Part II focuses on developing better methods for identifying nondurable aggregates, and has resulted in a rapid new test based on the hydraulic fracture of aggregates. Part III describes field experiments to evaluate the freeze-thaw resistance of a number of specified concrete mixes and the use of sealants to mitigate D-cracking. Preliminary field performance results are presented.
