Interference of unburned and activated carbon in fly ash with air-entraining admixtures (AEA’s) in fresh concrete mixtures is a major concern in the concrete industry. Therefore, a rapid and accurate measurement of adsorption capacity of fly ash is of great interest to this industry.In this project, a new method is suggested, which can qualitatively and quantitatively measure different surfactan ...

Proposal title: Accurate and Rapid Measurement of Adsorption Capacity of Fly Ash in Concrete Mixtures Interference of unburned and activated carbon in fly ash with air-entraining admixtures (AEAs) in fresh concrete mixtures is a major concern in the concrete industry. Therefore, a rapid and accurate measurement of adsorption capacity of fly ash is of great interest to this industry. In Phase I, ...

THERE IS A NEED FOR A RAPID, NON-DESTRUCTIVE METHOD TO TEST FOR PROPER STEEL PLACEMENT IN PORTLAND CEMENT PAVEMENTS. ISTHE GOAL OF THIS PROPOSED PROGRAM TO DEMONSTRATE THE FEASIBILITY OF USING SHORT-PULSE, GROUND-PENETRATING RADAR AS A MEANS OF RAPID STEEL LOCATION IN CONCRETE PAVEMENT. A GENERAL BACKGROUND IN GROUND-PENETRATING RADAR THEORY IS PRESENTED. LABORATORY AND FIELD MEASUREMENTS USING A ...

THE FOLLOWING PROPOSAL PROVIDES THE RATIONALE AND METHODOLOGICAL APPROACH FOR THE DEVELOPMENT OF A GEOGRAPHICALLY DETAILED VISUAL DATABASE AND RETRIEVAL SYSTEM TO SUPPORT THE INTERMODAL PLANNING REQUIREMENTS OF ISTEA. CURRENTLY, STATES AND METROPOLITAN PLANNING ORGANIZATIONS HAVE ACCESS TO LIMITED AND INCONSISTENT FREIGHT INFORMATION RESOURCES WITH WHICH TO INTEGRATE INTO INTERMODAL PERFORMANCE SY ...

WITH THE PASSAGE OF THE INTERMODAL SURFACE TRANSPORTATION EFFICIENCY ACT, THERE BECAME A HEIGHTENED AWARENESS THAT OUR UNDERSTANDING OF INTERMODAL AND MULTIMODAL FACILITIES WAS LIMITED. PRIVATE ENTERPRISE HAS BEEN WORKING FOR MANY YEARS ON APPLICATIONS WHICH WOULD ALLOW FOR A PACKAGE TO MOVE FROM POINT A TO POINT B BY THE MOST EFFICIENT MODE, WITH THE PURCHASER OF THE SERVICE ONLY BEING AWARE OF A ...
