Nonlocal Finite Element Analysis of Strain‐Softening Solids
Publisher: American Society of Civil Engineers
Abstract: A two‐dimensional finite element formulation for imbricate non‐local strain‐softening continuum is presented and numerically demonstrated. The only difference from the usual, local finite element codes is that certain ...
Instability of Nonlocal Continuum and Strain Averaging
Publisher: American Society of Civil Engineers
Abstract: Nonlocal continuum, in which the (macroscopic smoothed‐out) stress at a point is a function of a weighted average of (macroscopic smoothed‐out) strains in the vicinity of the point, are of interest for modeling of heterogeneous ...
Performance Evaluation of an Eco-Binder Made with Slag and CFBC Fly Ash
Publisher: American Society of Civil Engineers
Abstract: Performance of the engineering properties of paste manufactured with an eco-binder was evaluated. The eco-binder without cement, SCA, was made with slag (S) and fly ash (CA) that had been created by circulating fluidized ...
Hydration Process and Compressive Strength of Slag-CFBC Fly Ash Materials without Portland Cement
Publisher: American Society of Civil Engineers
Abstract: This study mixed ground granulated blast-furnace slag (S) and circulating fluidized bed combustion (CFBC) fly ash (CA) without any portland cement or alkaline activator to produce an eco-binder, abbreviated as
Service Life Prediction for Concrete Structures by Time-Depth Dependent Chloride Diffusion Coefficient
Publisher: American Society of Civil Engineers
Abstract: This paper uses the time-depth dependent chloride diffusion coefficient obtained from the analytical solution of the nonlinear chloride diffusion equation at nonsteady state to propose a new life prediction model of concrete ...
Applying Gray Relational Analysis with Gray Numbers to Qualitative Identification of the Origin of Hydraulic Cement Clinker by Trace Elements
Publisher: American Society of Civil Engineers
Abstract: In recent years, increased attention has been given to the identification of the origin of hydraulic cement clinker with trace element contents. Establishing a standard pattern of the trace element for each origin can ...
Continuum Theory for Strain‐Softening
Publisher: American Society of Civil Engineers
Abstract: In heterogeneous materials such as concretes or rocks, failure occurs by progressive distributed damage during which the material exhibits strain‐softening, i.e., a gradual decline of stress at increasing strain. It is ...
Experimental Investigation of Bond-Slip Performance of Reinforcement in Two Green Concretes
Publisher: ASCE
Abstract: Application of green cement to replace ordinary portland cement (OPC) for concrete structures has become an active research interest. Using pull-out tests, this study explored the bond behavior of embedded rebar confined ...
Improving the Mechanical and Durability Performance of No-Cement Self-Compacting Concrete by Fly Ash
Publisher: ASCE
Abstract: The eco-binder with optimized fractions of ternary solid waste materials of ground granulated blast furnace slag (GBFS/slag), class F fly ash (FFA), and circulating fluidized bed combustion (CFBC) fly ash was successfully ...
