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.

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 1981 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper covers the evaluation of a ground granulated blast furnace slag as a partial replacement for portland cement in mortars and concrete. The ground slag was evaluated for strength-producing properties as well as durability performance when used to replace 40 to 65% portland cement. This study shows that the ground slag when used to replace 40 to 65% portland cement did significantly improve strengths, sulfate resistance, and alkali aggregate reactivity.

This book was released on 1992 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, Inland Steel Co. generates approximately two million tons/year of iron blast furnace slag. This material is disposed of in a landfill which has a life expectancy to 1995. With the completion of the landfill rapidly approaching, an alternative means of slag disposal is necessary. Based on a review of the literature, it was determined that water granulation is one possible means for upgrading the utilization potential of blast furnace slag. This paper summarizes the results of a 1-ton/min pilot plant investigation (covering 101 furnace taps) aimed at determining if water-granulated slag from Inland's Blast Furnace No. 7, when suitably ground, can be used as a cementitious admixture for concrete and mortar. From the results it was concluded that a product of acceptable quality meeting ASTM Specification for Ground Iron Blast-Furnace Slag for Use in Concrete and Mortars (C 989) can be produced.

Available in PDF, EPUB and Kindle. Book excerpt: The mining industry is potentially the largest market in Northern Ontario for cement manufactured using granulated slag from Algoma Steel Corporation Ltd. in Sault Ste. Marie. A testing program was conducted in 1986 to evaluate ground granulated blast furnace slag (GGBFS) from Algoma Steel Corporation for possible use as an additive to mine backfill. The evaluation was based on compressive strength tests conducted at the laboratories of INCO Ltd., Falconbridge Ltd., Noranda Inc. - Geco Division, and Kidd Creek Mines Ltd., as well as at an independent laboratory. The objective was to evaluate GGBFS from the Reiss Lime Company of Canada for possible use as an additive to mine backfill.

Download or read book Production and Evaluation of a New Source of Granulated Blast Furnace Slag written by E. Douglas and published by . This book was released on 1988 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: A granulation pilot plant was installed at Algoma Steel Corp., Sault Ste. Marie, Ontario, for the production of about 40 metric tons of granulated blast furnace slag to be tested for concrete and mine backfill applications. The granulated slag was obtained by quenching the molten slag by jets of high-pressure water. Heat loss was maintained at the level expected when the full-size plant is in operation so as to generate a representative slag sample. The granulated slag was allowed to drain in the slag pit before being transported to the grinding facilities, where it was dried in a converted kiln, reducing the moisture content from 8 to 0.3%. The unit power consumption for grinding the granulated slag was similar to typical figures for grinding portland cement clinker in the lower Blaine range.

Available in PDF, EPUB and Kindle. Book excerpt: Ground granulated blast furnace slag (GGBFS) is a by-product of the iron-making process and because of its high calcium silicate content it has excellent cementious content and has been used in the construction industry for years as a replacement for ordinary Portland cement (OPC). GGBFS is also routinely used to limit the temperature rise in large concrete pours and is therefore a desirable material to use in mass concrete placements where control of temperatures is an issue. The more gradual hydration of GGBS cement generates both lower peak and less total overall heat than OPC. GGBFS was approved for use at a 70% replacement even though it is only allowed to use a maximum 25% instead of cement. It has a higher proportion of the strength-enhancing calcium silicate hydrates (CSH) than concrete made with only OPC, and a reduced content of free lime, which does not contribute to concrete strength.
