Abstract: This study reports the findings of an experimental investigation for alkali silica reaction (ASR) between reactive aggregates and the geopolymer matrix. Specimens were prepared using one Class C and two Class F fly ash ...

Abstract: The durability of steel reinforced-concrete specimens made from three alkali-activated fly ash (FA) stockpiles and ordinary portland cement (OPC) in cyclic wet-dry chloride environment was evaluated over a period of 12 ...

Abstract: Decisions related to the rehabilitation of wastewater and water infrastructure are increasingly more complicated as the number and complexity of technologies in the marketplace increases. Established methods, such as ...

Abstract: This paper presents an overview of quality management theory and its application in the area of trenchless technology in general, and horizontal directional drilling (HDD) in particular. Current practices that support ...

Abstract: This paper reviews and evaluates three current design practices for calculating tensile loading during the installation of steel and polyethylene pipe using horizontal directional drilling (HDD). A sensitivity analysis of ...

Abstract: Emergency preparedness agencies are promoting community resiliency in the face of disasters through community involvement and planning. One aspect of such programs is the incorporation of disaster planning into the community ...

Abstract: In recent years, the utilization of horizontal directional drilling (HDD) in urban areas for the installation of telecommunication, utilities, or municipal services has experienced a rapid growth. The hazards and complexity ...

Abstract: A literature review is presented that identifies a number of areas where procedures for the engineering design of bored installations in soil using horizontal directional drilling (HDD) can be improved through a more ...

Abstract: Horizontal site characterization technologies present a rapidly evolving alternative to traditional vertical site investigation methods for subsurface investigations of large diameter trenchless construction projects. A ...

Abstract: The use of horizontal directional drilling (HDD) technology in environmental remediation operations is an emerging field. An overview of horizontal environmental well technology, and its use in North America is presented. ...
