This book was released on 2002 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A two part laboratory experimental program was conducted to evaluate strength and durability of various concrete mix designs. In Part I of the study, the influence of using Grade 120 ground granulated blast furnace slag (GGBFS) on the strength and durability properties of concrete was evaluated. GGBFS was used to replace Portland cement at replacement rates ranging from 0 to 75 percent. In Part II of the study, the influence of coarse aggregate size on the strength and durability of the ODOT Class C mix designs was evaluated. Coarse aggregate sizes included #57, #46, and #357. The ODOT high performance concrete mix designs were also included in this study.

This book was released on 2007 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research examined the properties of concrete containing grade 120 slag cement at replacement levels of 0%, 30%, and 50%. The primary concrete properties studied were compressive strength, split-tensile strength, and deicer scaling resistance. Material variations included four sources of ordinary portland cement and two types of coarse aggregate. Strength properties were studied at room temperature and 40°F mix and curing conditions. Deicer scaling resistance was studied for concrete cured under six curing conditions. Carbonation of concrete cured under these six conditions was also investigated.

This book was released on 2018-04-30 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The air-cooled blast furnace slag (ACBFS), the by-product of the pig iron making process, is often used as coarse aggregate in portland cement concrete (PCC) pavements, especially in the areas located in the vicinity of the iron mills. The utilization of this by-product as an aggregate in concrete offers environmental and economic benefits in the form of elimination of waste, decrease in the disposal costs, and reduction in need for mining of the natural materials. However, concerns exist with relation of the influence of these aggregates on the long-term durability of pavement concretes, especially at locations exposed to freezing and thawing environment.The objective of this research was to evaluate the influence of using the ACBFS aggregate (slag aggregate) as a replacement for natural aggregates on the properties of pavement concrete designed to meet the standard specifications of the Indiana Department of Transportation. A total of eight different concrete mixtures, four containing air-cooled blast furnace slag (ACBFS) as coarse aggregate and additional four containing natural dolomite, were used in this study.The mechanical and durability properties of these concretes were assessed by conducting series of tests prior and after the exposure to FT and WD cycles. In addition, changes in the overall physical appearance of the test specimens were also documented to aid in the evaluation of the effects of given exposure conditions on the deterioration process of concretes. In the case of a plain concrete, the analysis of the data collected during the study (i.e. the observed loss of strength, reduction in the dynamic modulus of elasticity, and physical changes in the appearance of the specimens) indicated that the calcium chloride (CaCl2) deicer caused the most severe distress, followed by the magnesium chloride (MgCl2). Specimens exposed to sodium chloride (NaCl) experienced the least damage and performed comparably to those exposed to distilled water (DST).The use of either Class C fly ash, slag cement or the combination of both as part of the binder was found to greatly increase the resistance of concrete to damaging effects of deicers.

Available in PDF, EPUB and Kindle. Book excerpt: This study evaluates Grade 120 Granulated Ground Blast Furnace Slag (GGBFS) and its effect on the properties of hydraulic cement concretes used in structural and pavement construction. Several mix designs, structural and pavement, were used for this evaluation with varying amounts of GGBFS used as a substitution for cement. These substitutions were a percentage by weight substitution. This study looked at the effects of slag on workability, constructability, durability and the compressive strength of the concrete. How GGBFS affected the concrete's set times was also critical in establishing the maximum substitution amount for Louisiana Department of Transportation and Development (DOTD) concrete structures and pavements. In addition, an informal telephone survey was taken with other state DOTs concerning their use and experience using GGBFS in concrete. This further assisted DOTD in the development of their own specifications for GGBFS concretes.

Available in PDF, EPUB and Kindle. Book excerpt: Performance of protective coatings for bridge decks is evaluated. Applications to bridges on the New York State highway system from 1961 through 1967 included 1) surface overlays, 2) membranes between the structural slab and bituminous wearing course, and 3) surface sealants. Overlays and membranes consisted of epoxies, polyesters, polyurethanes, latexes, neoprenes, silicone rubbers, and asphalt cutbacks. Surface sealants included silicones, distillate oils, and linseed oil. None of the surface overlays lasted more than 2 to 3 yr. However, a flexible polyester resin with fiber glass has provided satisfactory service for 1-1/2 yr and will remain under observation. Leakage of box-girder bridges with a membrane was primarily due to shear-key construction (since modified), while the same materials applied to composite bridges were associated with leakage that could not be explained. A more comprehensive survey of membranes is planned. Silicone and distillate oil sealants on non-air-entrained concrete did not improve long-term durability. Air-entrained concrete, both with and without linseed oil treatment, showed no evidence of deterioration after 4 yr of exposure.

Available in PDF, EPUB and Kindle. Book excerpt: The report discusses the following studies made to supplement the first report of this series: A study of effects of abbreviated moist-curing of concrete revealed no indications that concrete containing portland blast-furnace slag cements is more adversely affected than type II cement concrete. Tests of effects of portland blast-furnace slag cement on corrosion of reinforcing steel showed that corrosion at all ages and exposures tested was significantly less for steel in this concrete than for steel in type II portland cement concrete. Bond-to-steel tests indicated similar relations for both blast-furnace slag and type II portland cements.
