| Summary |
"The study was made to determine the effect of daily atmospheric temperature variation and curing on the warping and curling of plain concrete slabs and to study the effect of moisture on the warping of plain concrete slabs under nearly constant temperature conditions, by keeping the bottom surface of one slab wet and the other dry. Daily observations consisted of dial gage readings to determine the progressive variations in warping contours due to typical daily temperature curling. Trends were found for three months of dial gage readings and interpreted in terms of warping and curling of the slabs. The warping of outdoor slabs is much larger in magnitude than indoor slabs. The slab whose bottom surface was kept wet showed a slightly greater warping than the dry slab"--Abstract, leaf ii. |
