A Streamlined Decentralised Workflow for Obtaining Specific Mechanical Performance and Grade of 3DPC: Towards the Standardisation and Industrialisation of 3DCP

This work presents findings of ongoing experimental
research on 3D Concrete Printing, aiming at rationalising the
production parameters in favour of the final mechanical performance –
the grade – and at the same time proposing a decentralised approach for
the rapid definition of production standards and their reliable and
tamper-proof distribution to streamline the obtaining of a specific 3DPrinted
Concrete grade. Moving from preliminary considerations about
the fragmentation of current research, we suggest approaching the
standardisation problem from the basic principle of the structural
requirements rather than the development of hyper-specialised
materials. We propose a 2-step experiment with the creation of a
Distributed Ledger Technology-based decentralised framework acting
as a repository of experimental data from different production
laboratories, each with its specific setup and production settings. In the
first stage, the decentralised framework collects and analyses the
production data, detecting different production settings and mechanical
performance relations and patterns. In the second stage, the system
suggests optimised production settings for obtaining the required grade.
The decentralised framework constitutes the infrastructure for the
definition of production standards based not only on construction requirements but also considering the variable production setups, laying
the foundation for a smoother adoption of the standards.
