| ABSTRACT Residues from agricultural activity can be used to improve the quality of soil-based bricks, constituting an interesting alternative for their destination. The technical quality of soil-cement-plant residue bricks was evaluated by the combination of non-destructive and destructive methods. A predominant clayey soil, Portland cement and residues of husks of both rice and Brachiaria brizantha cv. Marandu (0, 10, 20, 30 and 40%, in mass, in substitution to the 10% cement content) were used. The bricks were submitted to destructive (water absorption and compressive strength) and nondestructive (ultrasound) tests for their physical and mechanical characterization. Results from both destructive and non-destructive tests were combined to determine the... |
