Evaluation of Pavement Curing Effectiveness and Curing Effects on Concrete Properties
Publisher: American Society of Civil Engineers
Abstract: This research was conducted to understand the effects of curing compounds and their application methods on concrete properties. In the research, three different curing compounds were selected and applied to lab and field ...
Activations and Properties of Cementitious Materials Made with Cement-Kiln Dust and Class F Fly Ash
Publisher: American Society of Civil Engineers
Abstract: Activation methods and their effects on strength development of nonclinker cements made with 50% cement kiln dust (CKD) and 50% Class F fly ash (FA) were investigated. These activation methods included (1) ball mill ...
Shrinkage and Fracture Properties of Semiflowable Self-Consolidating Concrete
Publisher: American Society of Civil Engineers
Abstract: Shrinkage behavior and fracture properties of five semiflowable self-consolidating concrete (SFSCC) mixes are studied, and their results are compared with those of conventional pavement concrete. In the study, prism tests ...
Prediction of Pavement Concrete Strength Development, Joint Sawing, and Opening Time Using FEMLAB
Publisher: American Society of Civil Engineers
Abstract: This paper describes a new model using Finite Element Modeling Laboratory (FEMLAB). The model can be used to predict pavement strength development and consequently the pavement joint-sawing and opening times. The strength ...
Effects of Modern Concrete Materials on Thermal Conductivity
Publisher: ASCE
Abstract: Thermal conductivity, k, is one of the key factors that control heat transfer in concrete. This paper presents the results of an experimental study conducted to analyze the effects of modern concrete materials, such as ...
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 ...
Effects of CNT and MgO–Type Expansive Agent on the Cracking Resistance of Face-Slab Concrete of CFRD
Publisher: ASCE
Abstract: Concrete face rockfill dam (CFRD) is a commonly used and cost-effective type of dams. However, random cracks are often seen in the face slab concrete (FSC) of a CFRD during construction, largely due to the shrinkage caused ...
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 ...
Performance of Cement Mortar with Inorganic Na2SO4·10H2O-Na2HPO4·12H2O Shape-Stabilization Phase Change Materials
Publisher: American Society of Civil Engineers
Abstract: Phase change material (PCM) is a strategic choice for storing energy and regulating the building temperature. It has been successfully integrated into cement-based materials, significantly affecting mechanical properties. ...
Investigation into Laboratory Abrasion Test Methods for Pervious Concrete
Publisher: American Society of Civil Engineers
Abstract: Portland cement pervious concrete (PCPC) has been increasingly used in concrete pavements during recent years. In addition to strength and permeability, abrasion durability is another important property of PCPC. In this ...
