摘要
混凝土早期由于水分的消耗和散失而导致塑性收缩及干燥收缩甚至引起开裂。混凝土养护是保证混凝土各项性能的指标,为其补充水分,以减少水分散失,降低混凝土开裂风险的重要技术手段。随着建筑行业人力成本增加、混凝土结构复杂性提升及混凝土施工信息化及智能化技术需求的提高,传统混凝土人工养护方式难以完全满足工程建造需求。基于此本研究概述了混凝土养护原理及技术要求,并详细分析了混凝土智能化养护技术,为全面推行混凝土结构养护智能化,提升工程建造智能化水平提供支撑。
In the early stages of concrete,the consumption and loss of moisture can lead to plastic shrinkage and dry shrinkage,which can easily cause cracking.Concrete curing is an important technical means to ensure various performance indicators of concrete,replenish water,reduce water loss,and reduce the risk of concrete cracking.With the increase in labor costs in the construction industry,the complexity of concrete structures,and the increasing demand for information and intelligent technology in concrete construction,traditional manual concrete curing methods are difficult to fully meet the needs of engineering construction.Based on this,this study provides an overview of the principles and technical requirements of concrete maintenance,analyzes and studies in detail the intelligent maintenance technology of concrete,providing support for the comprehensive promotion of intelligent concrete structure maintenance and improving the level of intelligent engineering construction.
