Development and Evaluation of Polymer Modified Portland Cement Concrete Lagging for Mine Openings.
NTIS: PB/81-223331 :127 pages
This report presents results of a study to develop and test a saran latex modified portland cement concrete lagging to be used as a replacement for wood lagging in underground mining. Two hundred and twenty latex modified concrete lagging were produced and shipped to the Bunker Hill Company in Kellogg, Idaho, for installation in their mine at the 17th level. The lagging are performing satisfactory after 22 months of exposure in the mine. The dow concept replaces wood systems by using reinforced latex concrete which outperforms and outlives wood systems, is more cost effective, and is completely nonflammable.
