Application of Rebound-Drill Core Method in Compressive Strength Detection of Concrete
In the compressive testing of concrete strength,because the traditional method will cause damage to the concrete structure,especially in the dense parts of the reinforcement,it is easy to form core fragmentation,result-ing in a high degree of damage.Therefore,taking the construction project of a high-rise apartment building as the research object,the rebound-drill core method is proposed to detect the compressive strength of concrete.First,the rebound value of the concrete surface is measured,and then the carbonization depth of the concrete surface is assessed according to the rebound value of the concrete surface,and the correction coefficient of the presumed compressive strength of the concrete is calculated,and finally the compressive strength of the concrete is mea-sured so as to realize the detection of the rebound-drilling core method in the compressive strength of the con-crete.The experimental results show that the damage degree of this method is low and it is effective in measuring the compressive strength of concrete.Therefore,the application of this method in practical engineering will be im-portant.
