This book was released on 1991 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to determine those properties of silica-fume concrete which might affect cracking and to develop guidance for minimizing cracking problems associated with the use of such concrete in future repair projects. Tests included compressive and tensile splitting strengths, modulus of elasticity, Poisson's ratio, ultimate strain capacity. uniaxial creep, shrinkage, coefficient of thermal expansion, adiabatic temperature rise, and abrasion erosion. None of the material properties of silica-fume concrete studied with the possible exception of autogenous shrinkage, indicate that this material should be significantly more susceptible to cracking as a result of restrained contraction than conventional concrete. In fact, some material properties, particularly ultimate tensile strain capacity, would indicate that silica-fume concrete should have reduced potential for cracking. While silica fume offers potential for improving many properties of concrete, the very high compressive strength and resulting increase in abrasion-erosion resistance are particularly beneficial in repair of hydraulic structures. These concretes should be considered in repair of abrasion-erosion susceptible locations, particularly in those areas where locally available aggregate might otherwise not be acceptable. The potential for cracking of restrained concrete overlays, with or without silica fume, should be recognized. Any variations in concrete materials, mixture proportions, and construction practices that will minimize shrinkage or reduce concrete temperature differentials should be considered.

Book Synopsis Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Evaluation of Concrete Mixtures for Use in Underwater Repairs by : Billy D. Neeley
Download or read book Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Evaluation of Concrete Mixtures for Use in Underwater Repairs written by Billy D. Neeley and published by . This book was released on 1988 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete mixtures were evaluated to determine which were most suited for placement underwater in thin lifts. The concretes were proportioned to have good workability, good abrasion erosion resistance, and good resistance to washing out of the cement paste. High-range water reducers (HRWR) were used to increase the workability and permit the use of low water cement ratios (W/C) to increase the resistance to abrasion erosion. Low W/C, silica fume, and antiwashout admixtures (AWA) were used to increase the resistance to washout. A washout test was used to determine the relative amount of cement paste lost when the concrete is exposed to a large volume of water. The two-point workability test was used to evaluate the relative workability properties of each mixture. The slump and air content were also measured for most of the mixtures. The test method for abrasion erosion resistance of concrete (underwater method) was used to determine the abrasion erosion resistance of each mixture. The results of these tests were used to determine the combination of materials necessary to produce concrete with the desired properties. Significant correlations that exist between the two-point measurements and washout measurements were examined. The effects that W/C, HRWR's, AWA's, fly ash, and silica fume have upon washout resistance and abrasion-erosion resistance were examined.

Book Synopsis High-Strength Concrete by : Michael A. Caldarone
Download or read book High-Strength Concrete written by Michael A. Caldarone and published by CRC Press. This book was released on 2014-04-21 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical book from a highly experienced author presents clearly the means and methods for designing, producing and using high-strength concrete. High-strength concrete offers many benefits. Higher compressive strengths allow for a reduction in the cross-sectional dimensions of columns and walls in buildings. Its greater stiffness allows for increasing building heights while controlling sway and occupant comfort. Civil structures such as bridges have benefited from greater span lengths, shallower beam sections, wider girder spacing, and extended service life. Illustrated with real life examples, through documented case histories, High-Strength Concrete will be a valuable resource for contractors, producers, inspection agencies, as well as engineers and researchers.
