Book Synopsis High Performance Concretes by : Paul Zia
Download or read book High Performance Concretes written by Paul Zia. This book was released on 1991. Available in PDF, EPUB and Kindle. Book excerpt: This state-of-the-art report summarizes the results of an extensive search and review of available literature on the mechanical properties of concrete, with particular reference to high performance concrete for highway applications. Included in the review and discussion are the behavior of plastic concrete as well as the strength and deformation characteristics of hardened concrete. Both short-term and long-term effects are considered. Based on the review of the available information, research needs are identified. It is concluded that much research is needed to develop data on the strength and durability properties of concrete which develops high strength, particularly very early strength.

Book Synopsis Evaluation of High Performance Concrete Pavements in Newport News and Hampton, Virginia by : Hamdi Celik Ozyildirim
Download or read book Evaluation of High Performance Concrete Pavements in Newport News and Hampton, Virginia written by Hamdi Celik Ozyildirim. This book was released on 2004. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the properties of three high performance concrete mixtures placed in a jointed plain concrete paving project on I-64 in Newport News, Virginia, to reduce the shrinkage and improve the flexural strength of the concrete. Two mixtures contained ground-granulated blast furnace slag with 2-inch and 1-inch nominal maximum size (NMS) aggregate, and the third mixture contained Class F fly ash with 1-inch NMS aggregate. Air-entrained paving concretes with satisfactory strength, low permeability, and dimensional stability were prepared using concretes with Class F fly ash or slag and 1-inch or 2-inch NMS aggregates. Slipform pavers satisfactorily placed these concretes. The test sections were in excellent condition after six winters based on a visual survey. Falling weight deflectometer data indicated a better load transfer with the larger aggregate size with everything else being equal. The study also evaluated the maturity method in the continuation of the project on I-64 in Hampton, Virginia. After the evaluation, the pavement was changed to continuously reinforced concrete and the concrete properties were tested in accordance with the recently introduced Guide for Mechanistic-Empirical Design of New and Rehabilitated Pavement Structures (known as the proposed AASHTO M-E Design Guide). In the Hampton portion, a Class F fly ash mixture with the 1-inch NMS aggregate was used. The use of large aggregate, provided the particle shape is acceptable, and uniform combined grading should be specified for concretes with reduced water and cement contents. The maturity method can be used to determine the pavement's readiness for opening to traffic and should be included in the specifications.

Book Synopsis Application of High Performance Concrete in the Pavement System by :
Download or read book Application of High Performance Concrete in the Pavement System written by . This book was released on 2002. Available in PDF, EPUB and Kindle. Book excerpt: Rigid pavements make up a significant percentage of highway systems in the United States and abroad. Concrete pavements provide an economical and durable solution for highway systems, because the pavements last longer and require less maintenance. Recently, there has been great interest in the construction of a higher quality concrete pavement, referred to as High Performance Concrete Pavements (HPCP), which could be in service longer and have lower maintenance and life cycle costs. General criteria were established by federal and state highway agencies to help in the design of these more durable and economical concrete pavements. This higher quality concrete pavement should incorporate recycled waste products, and utilize innovative construction equipment and procedures. These pavements should also have a shorter construction time and an ultra-smooth ride quality surface. With these criteria in mind, investigations have been launched to discover methods for improving the quality of concrete pavements. One area of interest involves the use of ground granulated blast furnace slag (GGBFS) as cementitious material in concrete pavement.
