RCC Non-Destructive Test
RCC Building Non-Destructive Test
Enkay Test House provides Non-destructive testing is a wide group of analysis techniques used in science and industry to evaluate the Building Health Analysis of a RCC material, component or system without causing damage. Since Non-destructive testing does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research.The non-destructive testing services we offer are designed to comply with a wide variety of industry standards, government contracts Society & Commercial Building, as well as unique customer requirements.
NDT Analysis has been done on , RCC Bridge, Old & New RCC Building to knowing the present health condition.
Rebound Hammer Test: For determining the estimated compressive strength of concrete and uniformity of concrete in terms of surface hardness as per IS 13311 (Part-2)-1992, ASTM C 805 02, BS 6089:1981 and BS 1881: Part 202, BSEN:13791, also establishing correlation chart between rebound hammer and other confirmatory test for estimated in-situ strength of concrete if required.
Ultrasonic Pulse Velocity Test: for ascertaining the quality of concrete, soundness and density of concrete, uniformity of concrete in terms of density as per IS 13311 (Part-1)- 1992, ASTM: C597-83, BS 6089: 1981 and BS 1881: Part 203 and BSEN:13791.
Core extraction and testing: Extracting the concrete core samples of minimum 70 mm diameter and 100 - 150 mm length (approx.) at select locations from RCC members of the structures covered under the study and evaluating the properties (fck value, grade of concrete) in the laboratory from the core samples selected. IS 456:2000; IS516:1959, IS 1199:2002; ASTM C-42, without encountering any steel reinforcement from the RCC members at specified locations by site in-charge withportable power driven core cutting equipment
Ferro Scaning:- Mapping of reinforcement by x-ray mapping at location of size 600x600mm for each picture shot and plotting the same on drawings.
Half Cell Potential Test: Measuring the Half Cell Potential readings with wheel electrode at the nodes of pre-marked grid points on concrete surface in a suitable grid for determining the probability of corrosion activity of embedded steel reinforcement in concrete with specified half-cell electrode in accordance with ASTM C876-1980 after moistening the concrete surface with water. The rate shall include surface preparation, moistening concrete surface for assessing the percentage risk of corrosion in reinforcement, Measuring the half-cell / surface potentials at selected locations on RCC members of the structures covered under the study to understand the extent of reinforcement corrosion and contourMapping of corrosion, Plotting the half-cellpotential readings in graphical presentation with potential contours plotted in terms of probable risk of corrosion of steel bar as per ASTM C876 [6]-1991
Carbonation Test: Measurement of carbonation depth by phenolphthalein spray test at selected locations on RCC members of the structures covered under the study to see the depth of carbonation as per BS EN 14630:2006, BS EN 13295:2004. Ration of Carbonation depth to cover depth is also measured to check the intensity of carbonation attack on steel bar.
