RISShort Fiber Reinforced Geopolymer Composites Manufactured by Extrusion
Publisher: American Society of Civil Engineers
Abstract: Geopolymer composites reinforced with short polyvinyl alcohol (PVA) fibers have been manufactured using the extrusion technique. The extruded products were thin plates with
Solid Phases Percolation and Capillary Pores Depercolation in Hydrating Cement Pastes
Publisher: American Society of Civil Engineers
Abstract: Solid phases percolation and capillary pores depercolation in hydrating cement pastes show great influences on mechanical properties and durability. In this paper, two nondestructive apparatuses, ultrasonic wave measurement ...
Analytical Equations and Numerical Simulation Describing the Pore and Solid Phase Distributions of Interfacial Transition Zones in Cement-Based Materials
Publisher: ASCE
Abstract: By combining the nearest surface distribution function and hydration kinetic equation, analytical equations are proposed to determine the pore phase and solid phase evolution in the interfacial transition zone (ITZ). In ...
Experimental and Simulation Study of Water Absorption in Unsaturated Concrete
Publisher: ASCE
Abstract: The aim of this research is to investigate the sorptivity and capillary coefficient in unsaturated concrete using the capillary water absorption experiment. The effects of water-binder ratio, fly ash content, and aggregate ...
Long-Term Performance of Sulphoaluminate Cement Blended with Different Contents of Limestone
Publisher: ASCE
Abstract: Compared with portland cement, sulphoaluminate cement (SAC) is considered a low carbon emission and low energy consumption cement. To further reduce the cost of SAC and promote extensive engineering application, the hydration ...
Ethylene Vinyl Acetate Copolymer Emulsion-Modified Alkali-Activated Slag Repair Material: Mechanical Strength and Durability Linked to Microstructural Properties
Publisher: American Society of Civil Engineers
Abstract: This study prepared modified alkali-activated slag repair materials by incorporating an ethylene-vinyl acetate copolymer emulsion (EVA). Sulfate attack tests, shrinkage tests, scanning electron microscopy, and mercury ...
Investigations on Water Vapor Adsorption–Desorption of Cementitious Materials and Its Induced Permeability under Isothermal Steady-State Flow
Publisher: ASCE
Abstract: H2O(g) adsorption-desorption of cementitious materials and their permeability is a vital indicator for their durability designs, which significantly affects the occurrences of corrosion, carbonization and freeze–thawing, ...
Effect of Load-Temperature-Osmotic Coupling on Chloride Ion Transport in Ultrahigh-Performance Concrete: Experiments and Models
Publisher: American Society of Civil Engineers
Abstract: Under complex geological circumstances, the deep part of ultrahigh-performance concrete (UHPC) experiences high stress, high temperature, and high permeability, resulting in the rapid corrosion and damage of concrete ...
Workability Properties of Specified Density Concrete with Municipal Solid Waste Incinerator Tailings Added as a Lightweight Aggregate
Publisher: ASCE
Abstract: The application of municipal solid waste incineration tailings lightweight aggregate (MSWI-TLA) for reducing carbon emissions, energy consumption, and environmental pollution of bulk solid waste treatment has received ...
