| 摘要： | The Kansas Department of Transportation (KDOT) has controlled alkali-silica reaction (ASR) for more than 70 years through the use of selected aggregates. Sand and gravel sources had to be tested using Kansas Test Method KTMR-23 (1999), Wetting and Drying Test of Sand and Sand-Gravel Aggregate for Concrete. Those aggregate sources that did not pass the Wetting and Drying Test had to be used with a “sweetener.” The sweetener had to make up a minimum of 30% (by weight) of the aggregate in the concrete. The most common sweeteners used have been limestone, calcite cemented sandstone, and a coarse gravel that passed the Wetting and Drying Test. Granite from Arkansas has recently been added as a sweetener in the Kansas City market. |
