Publisher: American Society of Civil Engineers
Determining the Water-to-Cement Ratio of Freshly Mixed Concrete: Applying the Modified Coarse Aggregate Correction Factor to the AASHTO T 318 Method
Publisher: American Society of Civil Engineers
Abstract: The water-to-cement ratio (w/c) is of great importance for concrete quality control. The microwave oven drying measurement method given in the AASHTO standard, Standard Method of Test for Water Content of Freshly Mixed ...
Influence of Cyclic Drying–Wetting and Carbonation on Oxygen Diffusivity of Cementitious Materials: Interpretation from the Perspective of Microstructure
Publisher: ASCE
Abstract: The oxygen diffusion coefficient of coastal concrete structures under cyclic drying–wetting and carbonation is one of the most crucial factors in its durability performance. In this work, the oxygen diffusion coefficients ...
Influences of Corrosion Degree and Uniformity on Bond Strength and Cracking Pattern of Cement Mortar and PVA-ECC
Publisher: American Society of Civil Engineers
Abstract: Engineered cementitious composites (ECCs), which have a strain-hardening behavior under tension, is widely used for repairing and retrofitting reinforced concrete structures. In such applications, the performance of the ...
Observational Consistency Comparison and Analyses of an X-Band Solid-State Radar and an X-Band Klystron Doppler Radar
Publisher: American Meteorological Society
Abstract: AbstractSolid-state weather radar transmitters offer great potential for increased reliability and maintainability, which have been proven to be critical for practical use. Although they have been implemented in radar ...
Investigation on the Properties of Asphalt Mixtures Containing Antifreeze Fillers
Publisher: American Society of Civil Engineers
Abstract: To investigate the properties of antifreeze asphalt mixtures (AFAC), the dense-graded and gap-graded asphalt mixtures, AC-13 and SMA-13, containing 2, 4, 5, 6, and 4 % by weight and 5, 6, 7, and 8 % by weight antifreeze ...
Prediction of Effective Chloride Diffusivity of Cement Paste and Mortar from Microstructural Features
Publisher: ASCE
Abstract: In this paper, a two-step model is proposed to predict the effective chloride diffusivity of cement paste and cement mortar. The prediction effective chloride diffusivity results of cement paste and cement mortar are ...
Correlating the Chloride Diffusion Coefficient and Pore Structure of Cement-Based Materials Using Modified Noncontact Electrical Resistivity Measurement
Publisher: American Society of Civil Engineers
Abstract: The electrical resistivity of hardened cement-based materials was measured in this work by a modified noncontact electrical resistivity measurement (MN-CM). The resistivity was further processed to compute the chloride ...
