1、前言近年来,随着商品混凝土加快,强度等级逐步的提高,泵送混凝土高强高性能混凝土的应用,施工速度加快,建筑物结构复杂,混凝土在施工期间经常出现大量的裂缝。特别是受力的重要部位,在浇灌混凝土后几天至十几天,即有裂缝产生,其形态各异,业主、施工、监理、质检部门,从不同角度进行分析,往往意见与分岐大,影响工程的开展。因此,有必要通过对影响裂缝产生的因素予以综合分析,得出较符合实际的建
1. Introduction In recent years, with the acceleration of commodity concrete and the gradual increase of strength grade, the application of pumping concrete with high strength and high performance concrete accelerates the construction speed and the structure of the building is complex. Concrete often has a lot of cracks during construction. In particular, an important part of the force, after pouring concrete a few days to ten days, that there are cracks, and its different shapes, owners, construction, supervision, quality inspection departments, from different perspectives, often views and differences , Affecting the development of the project. Therefore, it is necessary to make a comprehensive analysis of the factors that affect the fissure and draw a more realistic proposal
