CIGMAT Testing Programs for Coatings/Linings, Grouts and Pipe-Joints in Sewers
The testing programs were developed to evaluate the performance of coating, lining and grouting materials used in the rehabilitation of wastewater facilities and to quantify the infiltration at pipe joints using a combination of full scale and laboratory tests. For the coating/lining testing program, special testing chambers are available to verify the applicability of various coating materials to concrete pipe under a hydrostatic pressure of 105 kPa (15 psi). To quantify the bonding strength between the coatings and substrates (concrete and clay bricks) several ASTM/CIGMAT test methods are being used. A control test with Holidays has been developed to quantify the chemical resistance of coated materials to acidic environment. Based on the test results, it will be possible to develop relationships and quantify the effectiveness of various coating/lining materials. A combination of grout, grouted sand and model tests are being used to evaluate grouts for leak control at pipe/manhole joints, service connections and cracks. Grouts are being characterized using the working, physical, mechanical and durability properties.
