New Test Method for Additive Construction - Compressive Strength of Cementitious Additively Constructed Prisms
1. Scope
o This proposed standard test method outlines procedures for the fabrication and compressive strength testing of prism specimens made from additively constructed cementitious materials, with the objective of determining their compressive strength (??cAC) and verifying compliance with specified performance requirements for structural components produced through additive construction (??’cAC). It includes provisions for testing prisms produced both in laboratory settings and on-site alongside full-scale printed elements, supporting quality control and structural validation. The standard adopts SI units as the primary measurement system, with inch-pound conversions provided for reference only. It does not address all potential safety concerns and leaves it to the user to establish appropriate safety, health, and environmental practices and assess regulatory applicability.

Rationale
There is no current standard for the Evaluation and Testing of Printed Elements in Additive Construction to this day. As a constantly evolving industry which has been showing an increase in speed of development and of adoption, standardization is becoming the key to democratize and to make Additive Technology in the Construction Industry readily accessible to the public .
As current WKs are developing and working on the Design of Printed Elements in Additive Construction, the purpose of the group I am proposing is to look at Additive Construction from a Life-Cycle perspective.
It's necessary, in order to guarantee the safety of the public and to properly train the professionals in the engineering, construction, inspection and approval process of the Additive Construction industry, to provide a Standard that addresses the Testing and Evaluation procedures and methodologies for new and existing printed elements and materials.
The standard will not only provide guidance of the methods, but also will address the issue of Systems Dynamics, from a perspective of extending the life of the built product and potential changes in the destination of use.
The title and scope are in draft form and are under development within this ASTM Committee.
