Professor Liu Chao's team in Xi'an Jianda released the latest research results in top international journals

Recently, the team of Professor Liu Chao of our school's college has made important progress in the field of intersection of 3D printing concrete in the intersection of material interface and intelligent construction. It is the latest research results of "Hardnet Properties of 3D Print Concrete with Recycled Coarse Aggregate". "CEME and Concrete Research" journal, as the top academic journal in the field of construction and construction technology, ranks first in the international influence of cement base materials and structure. This is the first time that our school has published academic papers in the journal in the journal, and has achieved a breakthrough in the results of our school's top academic journals in this field. Dr. Liu Huawei is the first author of the dissertation, and Professor Liu Chao is the only communication author.

In recent years, 3D printing concrete technology has become a key link for the intelligent construction and transformation of the construction industry due to its advantages such as large curved surface span, spatial alien, model -free efficient construction, and digital accuracy control. Through technical research, Professor Liu Chao's team took the lead in the world to propose a 3D printing concrete "multiple partition-interface model" and "interface bonding multi-scale system" based on the characteristics of defect distribution, which reveals the mechanism of 3D printing concrete structural mechanics.

As the head of the "Thirteenth Five -Year Plan" national key R & D plan "Application Technology of the Grand Solid Waste Plastic Materials in 3D Printing Buildings", Professor Liu Chao has long been committed to research in the field of intelligent construction and solid waste resource -based applications to participate in my country. The first "3D Printing Concrete Basic Mechanical Performance Performance Test" standard, with Southeast University, Tongji University, Nanjing Jiayi Digital Adaptural Research Institute, CCCC First Highway Survey and Design Institute Co., Ltd. and other domestic 3D printing concrete leading universities and enterprises We have developed extensive cooperation, and the results have been demonstrated in Baiyun District, Guangzhou, Xi'an High -tech Zone and other places.

Study, civil engineering, material science and engineering cross -research fields, the team first broke through the high -volume 3D printing concrete preparation technology problem, and then realized the application of the construction of solid waste and recycled aggregate in the 3D printing concrete , Solve the bottleneck problem that plagues the high cost, touch/degeneration of the industry, and achieve the coordinated development of green building materials and intelligent construction. Innovative results take the lead in "Additive ManuoFacturn" (the number one in international influence in the field of 3D printing, IF: 11.632) and "Cement and Concrete Composites" (the international influence in the field of cement base materials and the field, if: 9.93 Published on the top, comprehensively explained the 3D printing coarse concrete structure hardening performance force mechanization mechanization mechanism mechanism.
