We actively participate on standard committees (ASTM/AASHTO) that deal cementitious materials and – participate in CCRL round robin testing/qualification. We were recognized by NIST (National Institute of Standards and Technology) for our quality of work product on cement testing. Using the right set of tools and our experience we can offer unique solutions to cementitious problems. In addition to cementitious materials, CTLGroup also offers variety of testing services on – materials such as natural pozzolans, slags, fly ash, silica fume, gypsum, lime and limestone, clay, iron ore and other raw materials as well as end products of concrete, mortar, and grout.
