Abstract: One common concern limiting the proliferation of high-volume fly ash (HVFA) concrete mixtures is the significant delay in setting that is sometimes encountered in field concrete mixtures. While several methods to mitigate ...

Abstract: Expressions for the protected‐paste volume of air‐entrained cement paste are derived using the hydraulic‐pressure mechanism of frost damage. The protected‐paste volume is the total common volume of cement paste protected ...

Abstract: In the companion paper, expressions were derived for the protected paste volume of air‐entrained cement paste on the basis of hydraulic pressure theory. The protected paste volume is the common volume of cement paste ...

Abstract: With the recent emergence of endocrine disrupting compounds as an important potable drinking water and reclaimed wastewater quality issue, the removal of two estrogenic compounds (17β-estradiol and fluoranthene) by ...

Abstract: Three viscosity modifiers (a commercial shrinkage-reducing admixture, a polypropylene glycol, and a cellulose ether) are used to reduce the effective diffusivity of chloride ions through mortars during a 1-year exposure. ...

Abstract: The Disadvantaged Business Enterprise (DBE) program is a federally funded program designed to provide opportunities for minority contractors to perform highway construction projects. The DBE program is six years old. A ...

Abstract: The small size and dynamic range of the best two-dimensional X-ray detectors are impediments to the use of three-dimensional X-ray computed tomography (3D-XRCT) for 100 percent inspection of ...
