ASTM C01/09 eye additive construction, 3D-printed material standards

Sources: ASTM International, West Conshohocken, Pa.; CP staff

ASTM International Committees C09 on Concrete and Concrete Aggregates and C01 on Cement are accepting candidate paper abstracts for Symposium on Standards Development for Cement and Concrete for Use in Additive Construction. The December 7-8 program will take place at the Renaissance Orlando at SeaWorld in conjunction with semiannual committee meetings.

Co-chairing the symposium are National Institute of Standards and Technology’s Scott Jones and Army Corps of Engineers’ Eric Kreiger. Along with other organizers, they aim to examine potential test methods for additive construction, or 3D-printed concrete or mortar, that may be standardized through ASTM committees. Among target paper or presentation topics are measurement of early-age (pre-initial setting) material properties; rheology (viscosity and yield stress); setting time; shape stability; measurement of hardened properties; compressive, bending and tensile strengths; durability; structural performance measurement; and, reinforcement techniques.

Authors must submit 250- to 300-word abstracts through an online platform no later than June. Technical information and questions can be obtained from or directed to Scott Jones, [email protected], or Eric Kreiger, [email protected]  —  www.astm.org/C01C09SymposiumCFPDec2020
