Abstract

Abstract: Three-dimensional (3D) concrete printing (3DCP) is a transformative construction technique that offers the potential for greater efficiency, customization, and architectural flexibility. This technology is becoming increasingly necessary in the construction industry due to its ability to reduce labour costs, increase productivity, and minimize waste. The use of alkali-activated materials in 3DCP is gaining attention due to their superior mechanical properties and lower carbon footprint compared to traditional Portland cement. These materials, which include agro-industrial by-products like fly ash, slag and bagasse ash are activated by alkaline solutions to form a binder. The development of sustainable, alkali activated 3DCP materials is a critical step towards environmentally friendly construction practices. The primary focus of this research is to investigate the hardened properties of 3DCP materials, including compressive strength, flexural strength, split tensile strength, bond strength, and Poisson’s ratio. These properties are fundamental for predicting the performance of 3D printed structures under various loading conditions.
基于农用工业废料的挤压三维混凝土打印硬化性能研究》综述论文
摘要:三维(3D)混凝土打印(3DCP)是一种变革性的建筑技术,具有提高效率、定制化和建筑灵活性的潜力。由于该技术能够降低劳动力成本、提高生产率并最大限度地减少浪费,因此在建筑行业越来越有必要采用。与传统硅酸盐水泥相比,碱活性材料具有更优越的机械性能和更低的碳足迹,因此在 3DCP 中使用碱活性材料正日益受到关注。这些材料包括粉煤灰、矿渣和蔗渣灰等农用工业副产品,经碱性溶液活化后形成粘结剂。开发可持续的碱活化 3DCP 材料是实现环境友好型建筑实践的关键一步。这项研究的主要重点是调查 3DCP 材料的硬化性能,包括抗压强度、抗弯强度、劈裂拉伸强度、粘结强度和泊松比。这些特性对于预测 3D 打印结构在各种加载条件下的性能至关重要。
