混凝土在现代工程建设中占有重要的地位。而在今天,混凝土的裂缝在一些施工现场仍然时有出现。究其原因,我们对混凝土温度应力的变化注意不够是其中之一。我们遇到的主要是施工中的温度裂缝,因此本文仅对施工中大体积混凝土裂缝的成因和处理措施做一探讨。1.大体积混凝土温度控制措施高层建筑地下室的底板一般较厚,有的厚达2-3m,属大体积混凝土施工。发生裂缝的主要原因是水化热高,与环境气
Concrete plays an important role in modern engineering construction. Today, concrete cracks still appear on some construction sites. The reason for this is that we do not pay enough attention to the changes in the concrete temperature stress. We are mainly dealing with temperature cracks during construction. Therefore, this article only discusses the cause of large-scale concrete cracks in construction and the treatment measures. 1. Mass Concrete Temperature Control Measures The basement of high-rise building basement is generally thicker, and some are as thick as 2-3m, which is a mass concrete construction. The main reason for the occurrence of cracks is the high heat of hydration and the environment
