在混凝土建筑物中，质量的好坏主要来自于混凝土强度。而保证混凝土强度关键则在于混凝土浇筑和养护。对于混凝土浇筑，应注意以下问题：一、要做好浇筑前准备工作1，处理好基础面、施工缝安设好模板、钢筋及预埋件等。基础面处理应平整密实，最好浇一层低号混凝土做垫层，以防 In concrete buildings, the quality is mainly from the concrete strength. The key to ensuring the strength of concrete is concrete pouring and curing. For concrete pouring, attention should be paid to the following issues: First, it is necessary to do a good job of pre-casting preparation 1. The basic surface and construction joints should be well-prepared with templates, steel bars and embedded parts. Fundamental surface treatment should be flat and dense, it is better to pour a layer of low-grade concrete as a cushion to prevent
