RISHydration of Clinker Phases in Portland Cement in the Presence of Graphene Oxide
Publisher: ASCE
Abstract: A new perspective on the hydration process of graphene oxide (GO)/cement composites is provided in this paper. The quantitative evaluation of GO on the hydration of four minerals and the dissolution sequence of the four ...
Experimental Study on Capillary Water Absorption Performance of Coral Sand Concrete in High-Salt Environment
Publisher: American Society of Civil Engineers
Abstract: The high-salt fog environment under a marine climate affects the capillary water absorption performance of porous building materials, causing changes in the thermal and wet properties of the materials and in their structural ...
Effect of Superplasticizers on Apparent Viscosity of Cement-Based Material with a Low Water–Binder Ratio
Publisher: American Society of Civil Engineers
Influence of Hybrid Fiber Reinforcement on Mechanical Properties and Autogenous Shrinkage of an Ecological UHPFRCC
Publisher: American Society of Civil Engineers
Abstract: Ultra-high-performance fiber-reinforced cementitious composites UHPFRCC) possess outstanding mechanical properties and durability. Strength development and shrinkage deformation are critical properties of UHPFRCC and should ...
Creep Behavior of Self-Compacting Rubberized Concrete at Early Age
Publisher: ASCE
Abstract: Self-compacting rubberized concrete (SCRC) is an excellent environment-friendly material that can be applied well in road and bridge engineering. In this study, the tensile and compressive creep performance of SCRC at early ...
Experimental and Numerical Analysis on Coupled Hygro-Thermo-Chemo-Mechanical Effect in Early-Age Concrete
Publisher: ASCE
Abstract: High-performance concrete easily generates early-age cracks due to its sharp and large temperature and relative humidity (RH) changes. The temperature and RH with and without axial compressive stress were experimentally ...
Cost-Effective UHPC for Accelerated Bridge Construction: Material Properties, Structural Elements, and Structural Applications
Publisher: ASCE
Abstract: Accelerated bridge construction (ABC) is becoming progressively popular in China due to its advantages in sustainable development. However, some challenges still prevent it from being further widespread, especially in some ...
Effects of Ultrafine Powders on the Properties of the Lubrication Layer and Highly Flowable Concrete
Publisher: ASCE
Abstract: The friction at the steel pipe–flowing concrete interface plays an important role in concrete pumpability. To reduce the friction or improve pumpability, in this paper, various ultrafine powders (nanoclay, nano-CaCO3, and ...
Rheological Properties of Cement Pastes with Polycarboxylate Superplasticizers of Varied Backbone Stiffness
Publisher: American Society of Civil Engineers
Abstract: Polycarboxylate (PCE) superplasticizers greatly affect the rheological properties of cementitious materials. Yet, the systematical influence of the PCE structure parameter on the rheological properties of cement paste is ...
