Chloropicrin movement and fungitoxicity in decaying southern pine laminated timbers

Creator:

Goodell, Barry Scott

Abstract:

Three groups of experiments were performed to determine an effective procedure for controlling decay in southern pine (Pinus spp.) laminated timbers. (i) A decaying laminated arch of southern pine was treated with chloropicrin. Movement of the chemical vapor through the arch and its effect on the decay and nondecay fungal...

Masters Thesis
Lateral bearing strength of fasteners in lumber-plywood joints treated with fire retardants

Creator:

Johnson, James W. and Oregon State University. Forest Research Laboratory

Abstract:

Joints were fabricated from different combinations of untreated and fire-retardant- treated (FRT) Douglas-fir dimension lumber and 3/8-inch plywood. Eight types of fasteners and three fire-retardant treatments were tested. Joint specimens were exposed 2 and 7 years in cold, standard, and warm-humid conditions, then tested in lateral bearing. Best overall performance...
