This book was released on 1972 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the investigation was to either validate or disprove the assumption that a water-cement ratio (W/C) in excess of 0.8 by weight for interior concrete containing 4-1/2-in. maximum size aggregate can be used in mass concrete construction, and to compare the properties of concrete containing 4-1/2-in. maximum size aggregate with those of the concretes containing 3- and 6-in. maximum size aggregates. The investigation consisted of a laboratory test program in which a series of six lean mass concrete mixtures, both with and without pozzolan, containing 4-1/2-in. maximum size aggregate were proportioned with identical W/C's that had been selected from the work of a previous investigation. Specimens were cast and tests were made to evaluate the mixtures for workability, strength, permeability, and durability.

Book excerpt: Atchison limestone was found to be unsatisfactory in freezing and thawing and its use in concrete has been discontinued. However, additions of 30 percent limestone aggregate were beneficial in controlling cement-aggregate reaction. Admixtures used in this investigation did not materially reduce cement-aggregate reaction and in some cases they appeared to increase reactivity. All Class A concretes were more durable in freezing and thawing than Class 46B concretes. Also air-entrained sand-gravel concretes were more durable in freezing and thawing than non-air-entrained sand-gravel concretes. Due to parallel to centerline placement of reference plugs, length change measurements of the pavement were of little or no value. Also dowel bars across the centerline tied two sections together, causing each section to influence the behavior of the other. This type of experimental layout should be avoided in future investigations. Beams fabricated with Platte river sand-gravel in combination with a low alkali cement (Av. 0.29% equivalent alkali) expanded from 0.3 percent to over 0.5 percent during ten to twenty years in an outdoor exposure yard.
