Comparison of three methods of preservative treatment for mine timbers
Comparative effectiveness of full-cell pressure, hot and cold and vacuum processes of preservative treatment using large, end-matched mine timbers, 8 in. × 8 in. × 6 ft of red pine and 7 in. × 8 in. × 6 ft of Douglas fir species; preservative used was chromated zinc chloride; retentions were measured by weighing, and chemical assays of side-and end penetrations were carried out on timber with approximately average retentions; zone analyses of single timbers with average retentions; zone analyses of single timbers with average retentions showed vacuum and hot and cold treatments to be inferior to pressure treatment in end penetration.
