RISLow-Alite Portland Cement in Steam-Curing Condition: Long-Term Compressive Strength and Permeability
Publisher: ASCE
Abstract: Steam curing is a commonly used method to obtain cement products with high early strength. It is popularly employed to produce prefabricated units in factory. However, the long-term performance of steam-cured products is ...
Effects of Asphalt Modification of Paste–Aggregate Interface on the Transport and Mechanical Properties of Concrete
Publisher: ASCE
Abstract: The addition of polymer emulsion in cement paste improves concrete impermeability. However, a high polymer emulsion content (usually 10%–20% of the mass of cement) is typically required to significantly improve the performance ...
Understanding the Impact of KNO3 on the Carbonation Behavior of γ-C2S
Publisher: ASCE
Abstract: γ-dicalcium silicate (γ-C2S) has received little attention in engineering applications due to its low hydraulicity, but it exhibits high carbonation reactivity and rapid strength gain with the added benefit of CO2 absorption, ...
Effect of Synthesis Conditions on Particle Size Morphology, Structure, and Acceleration Performance of C-A-S-H Nanoparticles
Publisher: ASCE
Abstract: In recent decades, C-S-H (calcium-silicate-hydrate) nanoparticles have been regarded as promising accelerators for early-age compressive strength enhancement of cementitious materials. In previous research, C-A-S-H ...
Early-Stage Hydration Retardation Mechanism in High-Ferrite Cement Clinker Doped with a Massive Amount of CuO
Publisher: American Society of Civil Engineers
Abstract: High-ferrite cement (HFC) has attracted widespread attention due to its advantages, such as low sintering temperature and excellent corrosion resistance. The application of Cu-containing waste in HFC will promote the cement ...
Surface Swelling Characteristics in Concrete under Salt Frost Exposure
Publisher: ASCE
Abstract: Salt scaling is a commonly observed durability issue in concrete exposed to a combined salt and frost attack. This damage is restricted to a very thin surface region causing the removal of mortar flakes. This study ...
Rheological Properties of Sulfoaluminate Cement–Asphalt Emulsion Paste
Publisher: American Society of Civil Engineers
Abstract: Sulfoaluminate cement (SAC)–asphalt emulsion (AE) mortar is a promising repair mortar for cement and asphalt emulsion (CA) mortar (CAM) used in high-speed railways. This paper deals with the rheological performance of ...
