混凝土强度评定方法及问题探讨

The Evaluation Method for Strength of Concrete and Study of Some Relevant Problems

本文简要介绍混凝土强度检验评定方法 ,用实例说明混凝土强度评定中可能出现的问题。评定混凝土强度时应计算出强度评定值 ,作为结构验算和加固补强的依据。非统计评定的效率较差 ,容易造成误判 ,最好更改其验收界限值的公式 ,使其适应混凝土设计方法。

This article discusses the evaluation method for compressive strength of concrete.Some project examples are used to describe some problems that may be encountered inconstruction site.Strength evaluation of concrete check and accept group should be figured out in terms of structure checking computation and remedy when needed.The non-statistic method of strength evaluation is somehow inefficient and may cause erroneous judgment.A change is advised to the formula for the non-statistic evaluation method to fit the design of concrete mixing proportion.
