Technical study on the production of blocks with composites of cement-wooden wastes from pallets of Pinus sp

Abstract A composite between particles obtained residual pallets of Pinus sp and cement was manufactured. Also, three methods were performance for wood particles: hot water washed, unwashed and unwashed with calcium carbonate (CaCO3). Different concrete-wood particle ratios were tested. Curing time...

Curing time was evaluated with ultrasonic pulse velocity (USV) and density of composites.

MOR ranged from 0.40 a 1.23 MPa and the blocks with unwashed wooden particles and with CaCO3 addition had the greatest significant differences. In abrasion strength, blocks with unwashed wooden particles reported the best results.
