|Title:||NON-STRUCTURAL COMPOSITES OF SAWDUST FROM ARGENTINA WOOD SPECIES AND COMERCIAL CEMENTS|
|Abstract:||The most part of residues generated during wood mechanic processing remains unexplored for construction material non-structural compounds production. Eucalyptus grandis and Cottonwood (Poplar sp) particles were submitted to several treatments, combining three cements (blast furnace slag, high initial strength and puzolanic). Firstly, binder reaction efficacy was investigated by means a calorimetric test (mixture hydration curves). After, cylindrical specimens were submitted to a compression test at 14 days old. Also, ultrasonic pulse velocity (UPV) was obtained during composite hardening process. Results obtained were very coherent detecting the effect of the biomass and cement types, the effect of the treatment applied to the wood particles and the interaction between these parameters. The most effective combination was obtained when a combination of E. grandis particles with blast furnace slag or high initial strength cements, both with 3% calcium chloride addition was used.|
