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 internat

Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to determine if reduction in air content by vibration of a well proportioned concrete mixture of relatively high cement content reduces the frost resistance of the hardened concrete and also to determine the effect of such reduction in air content on compressive strength. One 3/4-in. (19.0-mm) maximum-size crushed limestone aggregate concrete mixture was proportioned to have a compressive strength of approximately 5500 pst (37.92 MPa) at 28 days age. The mixture had an air content of 8 plus or minus %. Various vibration times were used to reduce the air content until the samples had an air content as low as could be practically obtained. Specimens were cast for determining compressive strength, resistance to freezing and thawing, and air void parameters to evaluate the effect of reduction in air content of the concrete on strength and frost resistance.

This book was released on 1994 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study, aimed at improving the freeze-thaw resistance of concrete, consists of three parts. Part I evaluates parameters affecting the freeze-thaw durability of concrete. A modification of the existing standard of method for determining the durability factor of concrete specimens is proposed, and a new procedure for fundamental transverse frequency (used in durability factor calculations) has been developed. Part II focuses on developing better methods for identifying nondurable aggregates, and has resulted in a rapid new test based on the hydraulic fracture of aggregates. Part III describes field experiments to evaluate the freeze-thaw resistance of a number of specified concrete mixes and the use of sealants to mitigate D-cracking. Preliminary field performance results are presented.

Download or read book Investigation of Frost Resistance of Mortar and Concrete written by Alan D. Buck and published by . This book was released on 1976 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specimens from 12 mortar mixtures and one concrete mixture were tested for frost resistance by acccelerated freezing-and-thawing tests and by dilation, for compressive strength, for freezable water (FW), and for weight changes after each of 8 different treatments. One variable of treatment was age of continuous moist curing; the other was age together with cyclic fluctuation of water pressure to simulate the conditions that would affect concrete at a low level in the Eisenhower Lock of the St. Lawrence Seaway among the results of these tests were: (1) Cyclic pressure treatment did not cause critical saturation to develop in most of the test specimens, including those most like the Eisenhower Lock concrete; (2) The concrete mixture which simulate the concrete in Eisenhower Lock with the large aggregate removed was frost resistant; (3) The usual relationships between frost resistance and variables of age, compressive strength, water cement (w/c) ratio, and air content were apparent; (4) The amount of air needed to obtain maximum frost resistance of the mortars increased with increasing w/c ratio to a maximum of about 9% air for a w/c ratio of 0.8 by weight; and (5) Data indicated that FW is not a useful index of frost resistance for air-entrained mortar or concrete mixtures.
