This book was released on 2017 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permeable concrete pavements have been increasing in popularity as a potential solution to reduce the amount of impermeable surface area associated with a project, reduce splash and spray on roadways, and reduce puddling for sidewalks. Permeable concrete pavement systems can potentially eliminate the need for conventional drainage systems. As important as these benefits are to surface runoff mitigation, there are concerns with the service life and structural strength of pervious concrete. The composition and structure of pervious concrete creates limitations to its mechanical strength properties and some challenges in its maintenance to achieve the expected service life. The performance of pervious concrete pavements is relevant to its geographical location and application as well. Eleven different pervious concrete mix designs were evaluated, including commercially available mixes and laboratory mixes. Mechanical properties such as compressive strength, flexural strength, flexural stiffness, tensile strength, and elastic modulus were measured. Shrinkage and freeze-thaw resistance were also tested. By modifying mix proportions, aggregate sizes and types in the pervious concrete mix designs, the observed changes in physical characteristics, mechanical properties, and hydrological properties were evaluated. Careful control of the mix design to provide proper workability within allowable transit times as well as the ability to withstand freeze-thaw, and modulus measurements were found to be important to creating successful field mixes from laboratory trials.

It explores the effects of various materials and process parameters on the mechanical, durability, and hydraulic properties of pervious concrete while examining their hydrological design and water quality. The ability to upscale the use of pervious concrete in construction applications is investigated through field evaluation, lifecycle assessment, and performance prediction using artificial intelligence. The volume presents the latest findings in pervious concrete research, filling a gap in previous relevant publications. The book comprises three parts: - Materials used in pervious concrete: Various materials are investigated to produce pervious concrete with adequate properties. Such materials include recycled aggregates from construction and demolition waste, geopolymers and alkali-activated materials, glass powder waste, municipal solid waste incineration ash, biochar waste biomass, and waste tire rubber aggregate, among others. - Hydrologic design and water quality: This part focuses on the main application of pervious concrete in pavements for stormwater control and management. It starts with a framework for the effective investigation of hydrologic and water quality performance of pervious concrete pavements. It also outlines techniques used for allocating pervious concrete pavements in urban planning. Modeling and predicting the hydrological performance of pervious concrete is also addressed. - Upscaling the use of pervious concrete: This part investigates the ability to predict the performance of pervious concrete using artificial intelligence. It also presents a lifecycle assessment of pervious concrete and evaluation of the field performance of pervious concrete. The clogging and maintenance processes of pervious concrete is also described.
Download or read book Engineered Concrete Mix Design and Test Methods written by Irving Kett and published by CRC Press. This book was released on 1999-11-29 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Romans used an early type of concrete made with natural pozzuolanic cement more than 2,000 years ago. Today, Portland Cement Concrete is the most important material of construction. Yet few books, if any, exist that offer an in-depth analysis of the mixing and testing methods of this vital hydraulic cement. Until now that is. Engineered Concrete: Mix Design and Test Methods helps engineers, as well as laboratory technicians, grasp a better understanding of Portland Cement and Portland Cement Concrete. The book is divided into several sections, with the first, Mix Design Procedures, explaining how concrete batches are designed, mixed, and measured for various consistencies. Another section details the tests of the primary component materials of concrete other than water - namely Portland Cement, aggregates, and mortar - while the final section includes some of the fundamental concrete testing procedures for different strength parameters in conformity with the standards of the American Society for Testing Materials. While focusing solely on Portland Cement, the book also includes information on other hydraulic cementitious materials and additives because of their modern applications. Solidly researched and written, Engineered Concrete: Mix Design and Test Methods provides a clear understanding of mix design and testing of Portland Cement Concrete. As every civil engineer knows, it is the most versatile and important material of construction, and will probably remain so as far into the future as we can see.

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.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning, a finite element modeling procedure has been developed using the vertical porosity distribution in pervious concrete and dividing the pervious concrete surface layer into three layers. Then, the model was validated against a field application and a factor of safety of 'Two' was proposed for repetition of truck traffic on the pavement, based on Pavement Condition Index (PCI) rating data. Finally, analyses were performed for different coefficients of friction between the layers of the pavement system. In between the finite element analyses, pervious concrete cylindrical specimens were prepared and equations were proposed to estimate the modulus of elasticity of pervious concrete for a given porosity.

Download or read book Concrete Pavement Mixture Design and Analysis MDA written by Peter C. Taylor and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any transportation infrastructure system is inherently concerned with durability and performance issues. The proportioning and uniformity control of concrete mixtures are critical factors that directly affect the longevity and performance of the Portland cement concrete pavement systems. At present, the only means available to monitor mix proportions of any given batch are to track batch tickets created at the batch plant. However, this does not take into account potential errors in loading materials into storage silos, calibration errors, and addition of water after dispatch. Therefore, there is a need for a rapid, cost-effective, and reliable field test that estimates the proportions of as-delivered concrete mixtures. In addition, performance based specifications will be more easily implemented if there is a way to readily demonstrate whether any given batch is similar to the proportions already accepted based on laboratory performance testing. The goal of the present research project is to investigate the potential use of a portable x-ray fluorescence (XRF) technique to assess the proportions of concrete mixtures as they are delivered. Tests were conducted on the raw materials, paste and mortar samples using a portable XRF device. There is a reasonable correlation between the actual and calculated mix proportions of the paste samples, but data on mortar samples was less reliable.
Download or read book Evaluation of Sustainability Durability and the Effect of Specimen Type in Pervious Concrete Mixtures written by Armando Marines Muñoz and published by . This book was released on 2012 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavements are one of the most important components of a city's infrastructure covering significant portions of urban land while simultaneously generating negative impacts such as the increase of urban temperature, lack of clear surface for rainwater percolation and traffic noise. In order to minimize the negative impact of pavements, several agencies have increased requirements for pavement sustainability, with pervious concrete being proposed as one of the leading materials to achieve this goal. The main characteristic of pervious concrete is its interconnected network of pores around the aggregate, which allows rainwater to percolate directly to the soil, potentially lowering pavement temperatures, improving skid resistance and reducing noise generation due to acoustic absorption. The purpose of this research is to further optimize the performance and enhance sustainability of pervious concrete by using waste materials, particularly Ground Granulated Blast Slag (GGBS), to partially replace cement, and Recycled Concrete Aggregate (RCA) to replace virgin coarse aggregate. Each concrete mixture will be tested for compressive strength, permeability, unit weight and durability. The successful completion of this project would promote the use of pervious concrete in pavements by developing concrete mixtures with optimized properties, lower cost, reduced CO2 footprint and high recycled material content.
