In the US, three separate standards may apply depending on the category of cement. For portland cement types, ASTM C150 describes: Cement Type Description Type I Normal Type II Moderate Sulfate Resistance Type II (MH) Moderate Heat of Hydration (and Moderate Sulfate Resistance) ...
Jan 15, 2016· Additive Manufacturing Material Standards. Using additive manufacturing allows layered materials to be made with a variety of materials such as plastic, metal, concrete, and maybe even someday human and other biological tissue.
ASTM additive manufacturing technology standards enable performance measurement of production processes and ensure the quality of end products made by additive manufacturing. ASTM standards provide uniform procedures for the calibration of additive manufacturing machines.
Additive Manufacturing (AM) with cementbased materials is an emerging technology that opens opportunities in the construction industry by reducing labor costs and increasing reliability of concrete infrastructure. Several institutions have demonstrated using concrete in AM by automating portions of the construction process.
Xypex Additive. Xypex Additive products, added to the concrete at time of batching, are part of the Xypex concrete waterproofing and protection system and represent one of three different ways to install Xypex Crystalline Technology into concrete.
Dec 06, 2005· ASTM has several standards for slip resistance. Chris Sullivan, regional sales manager for QC Construction Products, says the ageold ASTM standard for testing slip resistance of floor sealers, coatings and polishes has been ASTM D2047. But this standard has limitations, he says, because it only tests smooth, dry surfaces in laboratory conditions.
This is a list of ASTM International standards. Standard designations usually consist of a letter prefix and a sequentially assigned number. This may optionally be followed by a dash and the last two digits of the year in which the standard was adopted.

Bridging standards development with RD, and keeping pace with AM technology advances. the Additive Manufacturing Center of Excellence is a synergistic, collaborative, and efficient environment led by ASTM International. Its partners include Auburn University, NASA, EWI, and the Manufacturing Technology Centre.
Standards for Installation of Plaster. There are two main standards organizations in North America, the American Society for Testing and Materials (ASTM) and the Canadian Standards Association (CSA). ASTM generates consensus documents with the input of many people, including contractors, engineers, architects, and material producers/suppliers.
