This book was released on 1987 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents comparisons of initial evaluations of several concrete sealers and multiple layer polymer concrete overlays. The sealers evaluated included a solvent-dlspersed epoxy, a water-dlspersed epoxy, a silane, and a high molecular weight methacrylate. The multiple layer polymer overlays evaluated were constructed with two polyester resins and silica sand, two flexible epoxies and basalt aggregate, and three EP5-LV epoxies and silica sand. The report presents information on the permeability to chloride ion, the bond strength between the overlay and the base concrete, the skid number, and the cost of the sealers and overlays. The data collected to date indicate that penetrating sealers can usually be applied with a lane-closure time of less than 24 hours and can provide some protection against the infiltration of chloride ions at a low initial cost. Unfortunately, the sealers usually reduce the skid number, and their use will have to be restricted to bridge decks that have a high skid number, such as those with grooves made by tinlng or saw cutting. Of course, the sealers can be used to reduce the permeability to chloride ions of concrete components other than the deck. A high molecular weight methacrylate healer sealer covered with silica sand provided acceptable skid resistance and filled the cracks in a deck to a depth of about 0.5 in, depending on the width of the cracks. A multiple layer polymer overlay designated by the VDOT as class-I waterproofing provides more protection against the infiltration of chloride ions than do the sealers, but the time required for installation is usually more than 24 hours, and the initial cost is usually more than twice as much. These overlays will usually increase the skid number of decks with low skid numbers. Unfortunately, the skid number of the overlay decreases with age, and depending on the traffic, may decrease to an unacceptable level in two to four years. The class-I waterproofing exhibited a high bond strength and low permeability to chloride ions after four years in service. Bridge engineers agreed to stop the use of class-I waterproofing in 1986 because of the low skid numbers. Multiple layer polymer overlays constructed with polyester resin are similar to .class-I waterproofing. Their initial cost is somewhat greater, because they are usually constructed in three or four layers rather than the two used for the class-I waterproofing and because the binder application rate is greater, than that used for class-I waterproofing. The polyester overlays have an advantage over class-I waterproofing in that they can be installed in stages and thus allow lane closures to be restricted to off-peak traffic periods. Also, multiple layer polymer overlays constructed with polyester resin should maintain an acceptable skid number for 10 years. Initial evaluations of multiple layer polymer overlays constructed with two flexible epoxies and basalt aggregate also look encouraging. One hundred cycles of temperature change had little effect on the sealers, class-I waterproofing, and the flexible multiple layer epoxy overlays. The polyester overlays, particularly those constructed with brittle resins, showed an increase in permeability and a decrease in bond strength after being subjected to 100 or more cycles of temperature change. A 300-cycle test may provide more definitive results. The performance of the sealers and multiple layer polymer overlays will have to be evaluated for at least five years to allow for an accurate assessment of life-cycle costs.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes a number of high-performance construction materials, including concrete, steel, fiber-reinforced cement, fiber-reinforced plastics, polymeric materials, geosynthetics, masonry materials and coatings. It discusses the scientific bases for the manufacture and use of these high-performance materials. Testing and application examples are also included, in particular the application of relatively new high-performance construction materials to design practice.Most books dealing with construction materials typically address traditional materials only rather than high-performance materials and, as a consequence, do not satisfy the increasing demands of today's society. On the other hand, books dealing with materials science are not engineering-oriented, with limited coverage of the application to engineering practice. This book is thus unique in reflecting the great advances made on high-performance construction materials in recent years.This book is appropriate for use as a textbook for courses in engineering materials, structural materials and civil engineering materials at the senior undergraduate and graduate levels. It is also suitable for use by practice engineers, including construction, materials, mechanical and civil engineers.

Download or read book Evaluation of Penetrating Sealers on Service Life of Concrete Infrastructure written by Goran Mohammed Fraj and published by . This book was released on 2022 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: In cold regions, thermal cycles and corrosion of reinforcements are the main factors that cause deterioration in concrete structures. Per each storm event, salt is used to melt snow and ice. Ultimately, water contains aggressive substances such as chloride that penetrate the concrete. When saturated concrete experiences FT cycles, it results in internal frost damage as well as surface salt scaling. The salt solution that contains chloride ions, at normal temperature, reaches calcium hydroxide and forms calcium oxychloride which is another form of damage observed mainly in concrete joins. On the other hand, infiltration chloride ions ultimately disrupt passive film around steel reinforcement and result in corrosion of steel. A recent trend is to extend the service life of existing infrastructure beyond the designed service life. This trend serves both sustainability, using less natural resources, and carbon footprint, generating carbon in the production of new materials. Therefore, in advanced countries, preservation, repair, and restoration as much as building new structures are important. This research explores the effect of different families of penetrating sealers on the durability performance of concrete. A large variety of penetrating sealers possessing different modes of action available in the market, research is needed to quantify and compare sealer impact on concrete durability. It should be mentioned that, along with reinforced concrete structures, a large portion of this dissertation focuses on the durability of joints in concrete pavements. The dissertation includes a selection of papers investigating a variety of important aspects of concrete joint durability. The papers include: • Evaluating penetrating sealer performance, such as depth of penetration, and wettability, • Effect of sealers on the freeze- durability of concrete joints, • Effect of sealers on the potential of calcium oxychloride formation, and • Effect of sealers on chloride ion penetration and concrete surface abrasion. The investigation conducted on concrete that considers durable concrete in terms of air voids and incorporating supplementary cementitious materials along with concrete possessing durability issues, such as improper air void system concrete, concrete contains aggregate that is susceptible to D-cracking, and concrete susceptible to form expansive calcium oxychloride. The results, presented in Chapters 3-6, show that the rate and timing of sealer application substantially affect sealer performance. Most sealers reduced both water absorption and chloride ions penetration. In addition, the durability of concrete varied depending on sealer type and mode of action. All sealers almost eliminated the potential of calcium oxychloride formation.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the test program reviewed in this report was to evaluate commercially available sealing products for use on bridge concrete and to evaluate the effect of abrasion on the performance of these products. One of the simplifying assumptions of the Alberta sealer test method is that the penetration of water and chloride ions into concrete are similar in degree. The reduction in water absorption due to the application of a sealer can be measured easily and allows an inference as to the reduction of chloride migration into the concrete. This test method allows comparison of the waterproofing performance of various concrete sealer products in terms of a percentage that compares the weight gained by absorption in sealed cubes with that gained by uncoated control cubes of the same concrete. The test results are organized into two categories of sealers, namely coating (barrier type) sealers and penetrating sealers.

This book was released on 2015-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete pavements represent a large portion of the transportation infrastructure. While the vast majority of concrete pavements provide excellent long-term performance, a portion of these pavements have recently shown premature joint deterioration. Substantial interest has developed in understanding why premature joint deterioration is being observed in jointed portland cement concrete pavements (PCCP). While some have attributed this damage to insufficient air void systems, poor mixture design, or chemical reaction between the salt and the paste, it is the hypothesis of this work that a component of this damage can be attributed to fluid absorption at the joints and chemical reactions between the salt and chemistry of the matrix. This paper discusses the role of soy methyl ester - polystyrene blends (SME-PS) as a potential method to extend the service life of concrete pavements by limiting the ingress of salt solutions. The report discusses field application of the SME-PS blends for field investigation in Lafayette and Fishers. Low temperature-differential scanning calorimetry (LT-DSC) techniques identified noticeable differences between plain mortar samples and mortar treated with SME-PS. The report also discusses the development of a test to assess chloride solution ingress during temperature cycling. The aim of this work is to provide background on some aspects that can lead to joint deterioration and provide early documentation showing that sealers may help to reduce the impact of deicers on joint damage, thereby extending the life of the concrete pavement. It should be noted that these sites as well as others are still ongoing and should be monitored for long term performance. Application procedure for SME-PS should follow manufacturer's recommendation.
