DescriptionEarlywood and latewood microtensile specimens from 12 trees of Pinus glabra Wal. were subjected to 10-percent solution of 5 acids and 3 bases at 90oC for up to 3 hours. Hydrochloric and sulfuric acids were the most damaging, lowering maximum tensile strength 27 and 17 percent in earlywood and 36 and 39 percent in latewood; they reduced work to maximum load 40 percent in earlywood and 65 percent in latewood. The bases increased maximum strength of earlywood 20 to 40 percent, increased modulus of elasticity 40 percent in earlywood and 18 percent in latewood, and raised work values for earlywood 40 to 50 percent.
