AGGREGATE TESTING
Aggregate Testing Laboratory in Qatar
TEL is an independent third-party aggregate testing laboratory in qatar, we provide you with highly specialized personnel, technology and testing, material test such as gabbro, limestone, grading, crushing value, soundness, sulphate, chloride, sieve, plasticity index etc.
Aggregates make up the largest volume (66% to 78%) of material used in concrete and Asphalt. The aggregates for the normal use must be properly graded, hard, sound, durable, and free from chemicals or coatings of clay or other foreign materials that may inhibit the bond between the binding material and aggregate. Test on Aggregate must be performed to make sure that meet all these criteria.
TEL is one of the best aggregate testing laboratory in Qatar, we perform a wide range of the testing on aggregates. We take pride in our work and with our experienced staff and latest equipment. we promise to give you best possible and most reliable results.
