Standard Helps Improve the Durability of Concrete

A proposed ASTM International specification will fill the need for a standard covering the use of colloidal silica, a versatile nanoparticle used in concrete that aids in durability. ASTM’s concrete and concrete aggregates committee (C09) is developing the proposed release (WK60809). 

“Practical applications for colloidal silica in concrete include everything from walkway pavements to building foundations,” says Jon Belkowitz, director of research and development, Intelligent Concrete, LLC. 

“Colloidal silica will help end-users create a concrete mixture that has a longer service life without compromising fresh/hardened properties and getting grey concrete down the shoot and into the forms,” says Belkowitz.

Belkowitz notes that having an ASTM International standard on colloidal silica will give end-users including contractors, engineers, and architects more confidence in their decision to use it in construction projects.

ASTM welcomes participation in the development of its standards. Become a member of ASTM. The next meeting of ASTM International’s concrete and concrete aggregates committee is December 8-11 in Houston, Texas, USA.
