It has been an essential but unsolved issue to enhance the thermal capacity of PCMs while non-decreasing their mechanical strength. To this end, this work designs a novel 3D printing phase change aggregate to prepare concrete with prominent thermal capacity and ductility. The work investigated the effects of 3D printing phase change aggregate on the compressive strength and splitting tensile strength of concrete. The compressive strength of phase change aggregate concrete is 21.18 MPa, but the ductility of concrete improves. The splitting tensile strength was 1.45 MPa. The peak strain is 11.69 \u00d7 10\u22123, nearly 13 times that of basalt aggregate concrete. Moreover, using 3D printing phase change aggregate reduced concrete\u2019s early peak hydration temperature by 7.1%. The thermal insulation capacity of the experiment cube model with phase change concrete has been improved. The results show that the novel 3D printing change aggregate concrete has good mechanical properties and latent heat storage, providing a guideline for applying PCMs in building materials.<\/jats:p>","DOI":"10.3390\/ma15238393","type":"journal-article","created":{"date-parts":[[2022,11,25]],"date-time":"2022-11-25T04:05:39Z","timestamp":1669349139000},"page":"8393","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Novel 3D Printing Phase Change Aggregate Concrete: Mechanical and Thermal Properties Analysis"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0134-9373","authenticated-orcid":false,"given":"Jinyang","family":"Jiang","sequence":"first","affiliation":[{"name":"School of Material Science and Engineering, Southeast University, Nanjing 211189, China"}]},{"given":"Chaolang","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Material Science and Engineering, Southeast University, Nanjing 211189, China"}]},{"given":"Fengjuan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Material Science and Engineering, Southeast University, Nanjing 211189, China"}]},{"given":"Wenxiang","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Mechanics and Materials, Hohai University, Nanjing 211100, China"}]},{"given":"Liguo","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Material Science and Engineering, Southeast University, Nanjing 211189, China"}]},{"given":"Zhaoyi","family":"Chen","sequence":"additional","affiliation":[{"name":"China Railway Design Corporation, Binhai New Area, Tianjin 300308, China"}]},{"given":"Wei","family":"Su","sequence":"additional","affiliation":[{"name":"China Railway Design Corporation, Binhai New Area, Tianjin 300308, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"788","DOI":"10.1007\/s11595-018-1894-9","article-title":"Study on Graphene Oxide Modified Inorganic Phase Change Materials and Their Packaging Behavior","volume":"33","author":"Xiao","year":"2018","journal-title":"J.
