Rezumat:
         Acest studiu investigheaza metodele de imbunatatire a absorbtiei de catre lemn uleiului de motor uzat. S-au procurat probe din lemn de Gmelina arborea, Terminalia superba, si Ceiba pentandra si au fost taiate in epruvete cu dimensiunile de 35mm x 35mm x 220mm. Epruvetele au fost cantarite si impartite in doua seturi. Un set a fost incizat iar celalalt set neincizat. Toate probele au fost uscate in etuva la 103±20C, s-au notat masele lor in stare anhidra si au fost tratate cu ulei de motor uzat utilizand tratarea la cald, imersia la rece si metoda pensularii. Probele tratate au fost, de asemenea, expuse la atacul termitelor.
         Rezultatele au aratat ca absorbtia procentuala medie in lemnul tratat in prealabil (incizat si neincizat) a fost de 13.6% si respectiv 11.6%. Rezultatele analizei absorbtiilor medii procentuale au aratat diferente semnificative intre tratarea in prealabil a lemnului, metoda de aplicare si consumul specific al fiecarei specii lemnoase. Incizarea probelor din lemn a determinat cresterea consumului specific, dar si structura anatomica a speciilor a avut un efect semnificativ asupra ratei absorbtiei. Clasificarea ASTM a aratat ca folosirea uleiului de motor uzat este o metoda de protectie prin tratare la cald care confera o protectie suficienta impotriva termitelor.

Cuvinte cheie: protectia lemnului, ulei de motor uzat, absorbtie, incizie, termite.
