Cementitious Materials
If you are cement manufacturer that is looking to optimize your production or if you are an end user that is trying to determine the general composition of a cementitious material, you are at the right place. CTLGroup has been the preferred destination for a variety of construction industry clientele and government agencies for services that go beyond routine cement testing. We have gained over 100 years’ worth collective knowledge on cement characterization and vast experience testing numerous types cementitious products over the decades.
Qualifications
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. Below is a list of routine materials related tests we offer.
