RISStudy of the Effectiveness of Cement Kiln Dusts in Stabilizing Na-Montmorillonite Clay
Publisher: American Society of Civil Engineers
Abstract: The feasibility of using cement kiln dusts (CKDs) as potential stabilizing agents for Na-montmorillonite clay was investigated using a suite of four CKDs with different chemical and physical characteristics. The Atterberg ...
Closure to “Study of the Effectiveness of Cement Kiln Dusts in Stabilizing Na-Montmorillonite Clay” by Sulapha Peethamparan and Jan Olek
Publisher: American Society of Civil Engineers
Effect of Mixture Composition and Initial Curing Conditions on Scaling Resistance of Ternary (OPC/FA/SF) Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of a multiobjective laboratory study on scaling resistance of ternary concrete containing Class C fly ash (FA) and silica fume (SF). Several experimental variables were included in the ...
Water Transport in Concrete Damaged by Tensile Loading and Freeze–Thaw Cycling
Publisher: American Society of Civil Engineers
Abstract: In service, concrete can develop cracks or microcracks that can influence the transport of liquids and ions. This paper describes an investigation of fluid transport in concrete damaged by tensile loading or freeze–thaw ...
Effects of Air-Cooled Blast Furnace Slag Aggregate on Pore Solution Chemistry of Cementitious Systems
Publisher: ASCE
Abstract: Air-cooled blast furnace slag (ACBFS) can be used to replace naturally mined aggregates to minimize the environmental and economic costs associated with construction. This paper compares pore solution chemistry of mortars ...
Surfactant-Assisted Purification of an Impure Kaolinite Clay to Improve Its Pozzolanic Reactivity in Concrete
Publisher: ASCE
Abstract: Supplementary cementitious materials (SCMs) are beneficial for improving concrete’s long-term performance, durability, and environmental impact. Impure clay sources are abundant and when calcined, may serve as suitable ...
Development of Specification for Accelerated Approval Process of Flowable Fill Mixtures
Publisher: American Society of Civil Engineers
Abstract: The flowable fill is a self-compacting cementitious material used primarily as an alternate backfill in lieu of compacted soil. In general, from the applications point of view, the flowable fill mixtures can be divided ...
Reclaimed Asphalt Pavement Limits to Meet Surface Frictional Requirements
Publisher: American Society of Civil Engineers
Abstract: Reclaimed asphalt pavement (RAP) is widely used to construct new asphalt pavement layers, but its use is often limited in surface courses because of concerns about frictional performance, especially in areas where ...
