Nielsen's research is being conducted in collaboration with Rapid City's Materials Recovery Facility ( MRF) and under the supervision of Dr. M. R. Hansen, SDSM& T Associate Professor of Civil Engineering. The SDSM& T graduate student's preliminary research findings indicate that it may be feasible to use crushed recycled glass to replace 20% of the aggregate ( sand and rock) in concrete. After conducting a battery of standard strength and durability tests, Nielsen also has determined that adding fly ash as 20% of the cementitious materials counteracts the tendency for glass to expand in concrete due to alkali silica reactivity problems. Nielsen is scheduled to present her preliminary research findings at the 34th Annual Concrete Conference to be held March 6, 1998, at SDSM& T. She also will make a presentation during the open paper session of the spring convention of the American Concrete Institute, the premier concrete organization in the world. In addition, the SDSM& T graduate student has been accepted to present her paper, " Using Recycled Glass as Aggregate in Concrete", at the Sydney Diamond Symposium on the Materials Science and Engineering of Concrete Cementitious- Based Compounds. This is an international specialty conference on concrete. " This research holds the potential of finding a viable market for recycled glass, which could benefit the operation of the City's Materials Recovery Facility, " says Dr. M. R. Hansen. " Using recycled materials can be very energy- efficient and cost effective when local markets can be found for the materials. The aluminum, steel and plastics also retrieved at the MRF already have valuable markets." " It should be emphasized that this is research in progress which shows promising results for the current combination of materials." adds Hansen. " Future monitoring is essential and additional research is required." ++ 30++ ( f:\ programs\ dept\ univrel\ pressrele\ 298\ Concrete Recycling Research fax\ stwd) |
