一、前言现在水泥混凝土路面混凝土的设计强度是以抗折强度为标准。但是,制备的抗折强度标准试件的重量比抗压强度试件重要的多,试验时花费的劳力也多。于是有关研究单位,曾在试验室内制备了大量的混凝土抗折强度、抗压强度及抗劈裂强度试件,以探索其间的强度关系,力求简化控制混凝土的施工质量。本研究是结合混凝土路面施工,控制混凝土施工质量,在工地间隔进行大量制备混凝土抗折及抗压试件,以及混凝土路面完成后,在某些路段用混凝土取芯机取芯试件进行试验,以探索其间的关系,实际数据关系式对现行国(部)颁的混凝土路面设计规范,施工规范的不断充实和完善,有一定的建设性作用。
First, the preface Now the design strength of concrete pavement concrete is flexural strength as the standard. However, the weight of the prepared specimen with the bending strength is more important than that of the specimen with the compressive strength, and the labor involved in the test is large. So the relevant research units, in the laboratory have prepared a large number of concrete flexural strength, compressive strength and anti-splitting strength of the specimen to explore the relationship between the intensity, and strive to simplify the control of the construction quality of concrete. This research is based on the construction of concrete pavement, controlling the quality of concrete construction, preparing a large number of concrete flexural and compressive specimens at the site, and after the completion of concrete pavement, To explore the relationship between the actual data relations on the current state (ministry) issued concrete pavement design specifications, construction standards continue to enrich and improve, have a certain constructive role.
