| dc.description.abstract | ACACIA DEALBATA LINK, KNOWN AS MIMOSA IN PORTUGAL, IS AN INVASIVE HARDWOOD SPECIES WITH POTENTIAL FOR CONSTRUCTION USE, BUT RESEARCH IS LIMITED. THE AVAILABLE STOCK OF SMALL-DIAMETER JUVENILE WOOD LOGS CAN HELP REDUCE THIS GAP, BUT TANGENTIAL CRACKING AT LOG ENDS CHALLENGES FASTENER CONNECTIONS. THIS STUDY EVALUATED DIFFERENT TREATMENTS TO CONTROL AND REDUCE END-FACE CRACKING IN SMALL WOOD LOGS DURING AIR DRYING, AN ECONOMICAL AND ENVIRONMENTALLY FRIENDLY PROCEDURE. THE EXTREME TWO-THIRDS OF SIXTEEN MIMOSA LOGS WERE SUBJECTED TO TWO TREATMENTS: ONE WITH LONGITUDINAL KERFS 15 MM DEEP ALONG THE LENGTH (TWO AND THREE KERFS) AND THE OTHER WITH A HOLLOW IN THE CENTER UP TO HALF THE LENGTH (16 MM AND 30 MM DIAMETERS). OVER 219 DAYS OF AIR DRYING AND COMPARED WITH THE CENTRAL PART, KERFING TREATMENTS SIGNIFICANTLY REDUCED OUTER-WOOD TANGENTIAL CRACKING (P < 0.001), WITH THE THREE KERFS ALSO REDUCING CRACK NUMBERS (P < 0.05) BUT INCREASING SIGNIFICANTLY CRACKS NEAR THE PITH (P < 0.01). THE 30 MM CENTRAL HOLLOW SIGNIFICANTLY REDUCED CENTRAL PERFORATION CRACKING (P < 0.05). PROSPECTIVELY, THE RESULTS SUGGEST THAT A COMBINED TREATMENT APPROACH INVOLVING CROSS-CUTS COULD HELP REDUCE AND/OR CONTROL END CRACKING, THEREBY IMPROVING THE SUITABILITY OF WILD MIMOSA LOGS FOR CONSTRUCTION USE. | |
