摘　　要：通过采用当地原材料进行混凝土配合比、成型、养护、取芯、加工、试压,对大量数据进行分析、归纳、总结,着重研究了φ75mm×75mm混凝土芯样强度值与φ100mm×100mm混凝土标准芯样和150mm×150mm×150mm同条件的标准试块强度值三者之间的相关关系,并在综合分析国内研究成果的基础上,探讨了小直径芯样与标准直径芯样所测混凝土抗压强度之间的修正关系。Abstract： Through the use of local raw materials concrete coordinating proportion,molding,curing,core sampling,processing,pressure test,a large amount of data are analyzed and summarized;The relationship of standard strength of Ф75 mm concrete core, Ф100 mm concrete core and Ф150 mm concrete core are studied under the same conditions.Moreover,amendments to the relationship of concrete compressive strength between small diameter and standard diameter are given on the basis of a comprehensive analysis of domestic research results.
