| 摘要： | The performance of a silane-penetrating water-repellent material applied to three concrete mix types was evaluated using alternative test procedures. One of the mix types was similar to standard reference concrete often used in laboratory testing. The other two mixes represented structural deck concrete and high-density overlay concrete, with correspondingly lower water-cement ratios and varying mix designs. Performance was evaluated with respect to depth of penetration, absorption, water vapor permeability, and chloride ingress. Test procedures and mix type were both found to affect the parameters used to evaluate the performance of the treated concretes. Results indicate the need to represent field conditions (such as mix design) to the extent possible in order to better predict field performance with laboratory tests. |
