Available in PDF, EPUB and Kindle. Book excerpt: Concrete durability in climates where freezing and thawing occurs is a continuing problem. It is particularly acute for highway and bridge structures, where de-icing salts are used to combat the effects of frost, snow and ice. These salts can cause damage to concrete and accelerate corrosion of reinforcements. This book presents the latest international research on this area, with contributions from North America and Europe which were presented at an international RILEM workshop.

This book was released on 1965 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Untreated and unprotected fresh concrete should not be exposed to freezing temperatures. If untreated fresh concrete freezes, it will not gain strength while frozen. It may gain strength upon resumption of normal curing. The ultimate compressive stress of normal concrete is increased with the use of a calcium chloride admixture. Air entrainment offers no advantage as an antifreeze agent. Air entrainment lowers the ultimate compressive stress of concrete. The percentage of air which is entrained in concrete is partially controlled by the mixing time. Calcium chloride is an excellent accelerating admixture when used in concrete which is cured under normal conditions. Use of the admixture increased the ultimate compressive stress of specimens cured in the moist room. The use of calcium chloride as an accelerating admixture permits fresh concrete which is exposed to freezing temperatures to gain some compressive strength. The strength attained is lower than it would be if the fresh concrete were protected from freezing and cured normally. Type III portland cement with a calcium chloride admixture produced the highest percentage of normal compressive stress when the fresh concrete was exposed to freezing temperatures. (Author).

Download or read book Effect of Mineral Admixtures and Coarse Aggregate Size on Compressive Strength and Freeze-thaw Resistance of Portland Cement Concrete written by Thomas Francis McDonnell and published by . This book was released on 2007 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ohio Department of Transportation (ODOT) has developed a series of portland cement concrete mix designs for use on all infrastructure projects throughout the state. The standard forms of these mix designs differ in terms of the compressive strength they are expected to achieve after a curing period of 28 days. Because of the state's climate, one requirement common to every mix design used by ODOT, however, is high resistance to damage from cycles of freezing and thawing. Options currently permitted by ODOT for varying these mix designs include the use of different coarse aggregate sizes and substitution of a portion of the portland cement with additional fine aggregate or one of three mineral admixtures. These admixtures include fly ash, ground granulated blast furnace slag (GGBFS) and micro silica. All of these admixtures are produced from materials that are recycled from processes unrelated to concrete production. These processes include coal fired steam generation, pig iron production and silicon manufacturing.The objective of the research presented in this thesis was to evaluate the effect that mineral admixtures and coarse aggregate on ODOT Class C (4,000 psi) concrete in terms of compressive strength and freeze-thaw resistance. These evaluations were performed through laboratory testing of specimens cast from individual mixes. Information is provided on the materials used to create a concrete mix, as well as a brief summary of the development of mix design methodologies. Detailed descriptions of the freeze-thaw resistance and compressive strength testing are also included, with a discussion of the associated mechanisms of failure. Conclusions are offered based on trends observed from analysis of the test data. In general, the results of the testing indicate that freeze-thaw resistance is not detrimentally influenced by the addition of mineral admixtures or the size of the coarse aggregate used. Each of the mineral admixtures does affect the resulting concrete mix in slightly different ways, and one may be more desirable than another based on required performance. In addition, all of the mix designs studied attained average compressive strengths in excess of the target value of 4,000 psi.

Available in PDF, EPUB and Kindle. Book excerpt: Recent developments have made a new generation of high-strength concrete a viable material for routine construction. The two principal developments are high-range water-reducing admixtures, which permit the placement of concrete of very low water-cement ratio, and silica fume, a pozzolan of extremely high fineness. The advent of this high- strength concrete has put requirements for strength and durability in conflict. Because entrained air reduces the strength of concrete, builders seek to eliminate or limit the use of entrained air. There are those who argue that high-strength concrete is of such a quality that entrained air is unnecessary. Much of the high-strength concrete currently being used is in buildings, where the question of durability is minor. The question, however, cannot be avoided in exposed highway structures. Service records of non-air-entrained high-strength concrete exposed to freezing are not conclusive. Hence, this report synthesizes the available knowledge on the subject. Its aim is to provide guidance to those who wish to use high-strength concrete in typical highway applications and to indicate where further information is needed.
