콘크리트 비파괴시험에 관한 기초적 연구 - 슈미트 햄머 방법 ( A Fundamental Study on Non-Destructive Testing of Concrete(1) )

This study was designed for analyzing the correlation between rebound number of schumidt hammer and compressive strength of concrete which are related by W/C, slump and curing age. Experimental equations of all case are as follows; 1) slump 8cm : Fc=13.1R-141 2) slump 12cm : Fc=13.5R-149 3) slump 18cm : Fc=12.1R-112 4) all slump : Fc=12.8R-132
