随着建筑业的快速发展,施工过程中常涉及到大体积砼的问题,由于大体积砼具有形体庞大、混凝土数量较多、结构厚、钢筋密、工程条件复杂、施工技术和质量要求高、混凝土绝热温升高和收缩等特点。大体积混凝土经常出现的问题不是力学上的结构强度,而是混凝土的裂缝。如何防止大体积砼的开裂,因此对施工技术提出了更高的要求,只有重视大体积砼的施工问题,避免裂缝的产生,才能确保施工质量,如何在施工组织和施工技术上采取必要的措施是本文研究的重心。
With the rapid development of the construction industry, the mass concrete problem is often involved in the construction process. Since the bulk concrete has the characteristics of large body, large amount of concrete, thick structure, dense steel bar, complex engineering conditions, high requirements of construction technology and quality, concrete Adiabatic temperature rise and shrink and so on. The problem that often occurs with mass concrete is not the mechanical strength of the structure, but the cracks in the concrete. How to prevent the cracking of large-volume concrete, so put forward higher requirements for construction technology, and only pay attention to the construction of large-volume concrete to avoid the generation of cracks in order to ensure the quality of construction, construction and construction techniques how to take the necessary measures This article is the focus of research.
