Construction material like timber, tiles, bricks, blocks etc. are tested for specific properties
Visual inspection for qualitative assessment of the state of timber to identify Defects and alterations including knots and fiber deviation, longitudinal splitting, ring shakes, biological damage and insect attacks. Using Non-Destructive Methods (NDT) to measure the moisture content of the wood, which severely affects its Mechanical properties and its susceptibility to degradation by decay, Ultrasonic investigations, Assessment of the material hardness and superficial consistence, Detection of internal defects and density variations by means of measure of drilling resistance, Compression tests and Bending tests (10 specimens type b) for modulus of elasticity and strength.
Measuring the moisture content in elements like timber and plaster, this test indicates the quality of the material especially after ageing over a long number of years.
Tile testing tests properties like the strength of the tile, water absorption, scratch resistance etc.
Brick testing is to be done for old bricks taken from masonry structures, special bricks, paver blocks etc.
