Study on Developing Rules of Compressive Strength of Concrete under the Conditions of Winter Construction
This paper takes the commonly used C30–C60 concrete entity model and the corresponding block as the research object in Tianjin, studying the difference about evaluation of concrete strength using different detection methods (rebound method and drilling core method, test cube test block method), the study found: during the winter construction, under the same condition curing and standard curing conditions, which test block strength curve shape was roughly same for the different strength grade of concrete, within the range of allowable error, the strength curve shape was logarithm curve trend; different grade strength of concrete reach its design strength required for different time, in this paper: C30, C35, C40, C50, C60 concrete can completely achieve its design strength at the age of 60d, 90d, 90d, 600°C·d, 600°C·d.
