摘要:在高层建筑结构设计中，混凝土施工技术是一个相当重要的环节，随着我国经济的发展，高层建筑在城市建谩中不断涌现。建筑工程的规模越来越大，我们不能将一般的混凝土施工工艺套用在高层建筑上施工上，这直接关系到高层建筑质量的好坏。为解决混凝土施工中的问题，本文对高层建筑混凝土施工方法进行了分析。

The scale of the construction project is more and more big, we can''t use ordinary concrete construction technology around high-rise building on construction, the relationship to a high building quality. To solve the problems of concrete construction, in this paper, the high building concrete construction methods are analyzed.

引言: 建筑工程中用的混凝土是由多种脆性材料组成的非均匀材料。具有较高的抗压性和良好的耐久性，同时也存在抗拉强度低、抗变形能力差，易开裂等显著特征。本文从高层建筑混凝土施工的质量要求、施工技术特点以及混凝土的浇筑等方面作了逐一阐述。

1 混凝土质量的施工要求

1．1混凝土强度及主要影响因素

混凝土质量的主要指标之一是抗压强度，从混凝土强度表达式不难看出，混凝土抗压强度与混凝土用水水泥的强度成正比，按公式计算，当水灰比相等时，高标号水泥比低标号水泥配制出的混凝土抗压强度高许多。所以混凝土施工时切勿用错了水泥标号。另外，水灰比也与混凝土强度成正比，水灰比大，混凝土强度高。水灰比小，混凝上强度低，因此，当水灰比不变时，企图用增加水泥用量来提高温凝土强度是错误的，此时只能增大混凝土和易性，增大混凝土的收缩和变形。粗骨料对混凝土强度也有一定影响，当石质强度相等时，碎石表面比卵石表面粗糙，它与水泥砂浆的粘结性比卵石强，当水灰比相等或配合比相同时，两种材料配制的混凝上。……
