一、前言水泥标准强度,是将水泥制成标准胶砂试件,在规定条件下养护28天的抗折与抗压强度,在生产实践中往往需要尽快确定某种水泥标号是否符合要求以及用已选定的水泥及时进行水泥混凝土混合料的配合比设计。其中水泥的标准强度是重要的依据和参数;但是水泥的标准强度需将胶砂试件经28天养护才能确定。这显然不能满足上述要求。因此,如何及时测定出水泥胶砂标准养护28天的强度。是人们十分关心的问题。
First, the preface Cement standard strength, cement is made of standard mortar specimens, curing under the conditions specified for 28 days of flexural and compressive strength, often in production practice need to determine whether a cement label meets the requirements and use Cement has been selected in a timely manner with the concrete mix design. Among them, the standard strength of cement is an important basis and parameters; however, the standard strength of cement needs to be determined after 28 days of curing. This obviously can not meet the above requirements. Therefore, how to measure the strength of cement mortar standard curing 28 days in time? People are very concerned about the issue.
