| 摘要： | Performance of microcracked field projects in Texas indicates no detrimental structural effects from microcracking. Even after failure at an early curing stage, the strength of the material recovers by continued cement hydration. At the end of the hydration stage, the strength of the previously failed material does not differ significantly from material simply cured to an age of 28 days. Additionally, the base modulus recovers after microcracking since the procedure takes place at an early curing stage. Microcracking imparts a temporary reduction in the base modulus. With additional curing time the base modulus rapidly recovers. Given the observed benefits and the lack of negative effects, microcracking can be considered for any properly designed CTB. / Supplementary Notes: See also PB2006-100907, PB2006-105535, and PB2011-103899.
