Summary of A 02
Selective paste intrusion (SPI) is a particle-bed based additive manufacturing technology in which aggregates are spread in thin layers and bond by cement paste. To qualify SPI for structural concrete elements, the inclusion of reinforcement is mandatory. The innovation introduced here is that reinforcement will be implemented in the SPI process using Wire and Arc Additive Manufacturing (WAAM) simultaneously. Different active and passive cooling strategies, e.g. particle surface functionalisation and the synthesis of new particles, will be developed to deal with the high temperatures during WAAM.
