Abstract: Measuring the thickness of concrete elements in the field can be challenging. In many cases, such measurements must be made from one side due to a lack of access to the opposite face. One technique commonly implemented in ...

Abstract: Traditionally, the extent of sulfate attack is qualified through visual rating or quantified by the percent expansion of slender bars completely submerged in sulfate solution. There are currently no standardized test methods ...

Abstract: This paper presents the findings of an investigation using the finite-element method to predict the distribution of temperatures within a hydrating massive concrete element. The temperature distribution produced by the ...

Abstract: Physical salt attack (PSA) or salt weathering occurs as a result of the crystallization pressures in concrete pores exerted by phase changes of salts that penetrate the concrete. The crystallization pressures cause ...

Abstract: As ultra-high-performance concrete (UHPC) becomes more widely used, the need for good concrete tensile tests for fiber-reinforced concrete has become apparent. However, there is not yet one universally used test method. ...

Abstract: Bottom and combined ash samples from municipal solid waste incinerator (MSWI) facilities in Florida were compared with industry aggregate standards to determine suitability for use as a road base. Although MSWI ashes tested ...
