中国建材检验认证集团股份有限公司（简称中国建材检验认证集团,英文简称CTC）起源于二十世纪五十年代,伴随新中国建材工业的发展而茁壮成长。经过六十余载的积极探索和不懈努力,已经发展成为国内建筑和装饰装修材料及建设工程领域内极具规模、综合性、第三方检验认证服务机构。
A judicial authentication institution to use on the road of drill core samples of compressive strength test,the use of the experimental results based on the concrete strength inspection evaluation criteria to assess the road concrete strength is not qualified. Presumption concrete strength evaluation and strength of concrete are discussed in the paper,the difference between a pointed out the problems existing in the compression test and the result evaluation,and then give the correct evaluation.The result shows that through the measured results,according to the concrete structure detection technology standard／＂ by which the strength of concrete estimate value for fcu,e=30.7 MPa is not less than the design requirements of C30 concrete compressive strength grade,can determine the test group （age） testing compressive strength of concrete in accordance with the design requirements.
