3D打印混凝土研究进展及其应用

摘要/Abstract

摘要： 近年来,3D打印混凝土技术凭借着免模板、高自动化与智能化的优势,吸引了越来越多的关注,在建筑工程等领域出现了诸多的成功应用案例。但是,3D打印工艺对混凝土的流变性能提出了更高的要求,而当前的混凝土相关标准与规范无法指导3D打印混凝土的设计。同时,受打印工艺的影响,3D打印混凝土的硬化性能和配筋技术也与传统混凝土有所差异。因此,本文从流变与可打印性能、配合比设计与制备、硬化性能及特点,以及配筋技术四个方面对3D打印混凝土的研究进展进行了综述。此外,为了全面展示3D打印混凝土技术的发展与应用,本文针对不同类型的3D打印混凝土工程案例以及特殊类型的3D打印混凝土进行了简要介绍,希望为3D打印混凝土的后续发展与研究提供参考。

Abstract: 3D printing concrete technology, with the advantages of free formwork, high automation and intellectualization, has attracted more and more concerns, and achieved successful application in the field of construction engineering and other related fields. However, 3D printing technology puts forward higher requirements to the rheological performance of concrete, while the current standards or codes for concrete are no longer applicable to guide the mix design of 3D printing concrete. Meanwhile, due to the effect of the printing process, the hardened properties and reinforcement technology of 3D printing concrete are different from that of conventional concrete. Therefore, this paper reviews 3D printing concrete from four main aspects, i.e., rheological and printable performance, mix design, hardened properties, and reinforcement technology. Besides, for comprehensively presenting the development and application of 3D printing concrete, different types of engineering projects and special types of 3D printing concrete are introduced in this review. This review is expected to provide a reference for the further development and research of 3D printing concrete.

Key words: 3D printing, concrete, rheological performance, printability, buildability, hardened property, reinforcement
