在凝结状态中的混凝土质量,通常是由它的抗压强度予以评定,理由有二:第一,理想的混凝土的质量与抗压强度有关;第二,混凝土的抗压试验比其他试验经济而简单。最大的骨料规格为1 1/2时(3.8厘米)的普通混凝土试件,其立方体为6时(15.2厘米),当骨料规格小于3/4时(1.9厘米)时,可使用4时(10厘米)的立方体。试件的大小对所得的抗压强度有一些影响,较小的试件得出的强度较高。例如4时(10厘米)的
The concrete quality in the condensing state is usually assessed by its compressive strength for two reasons: first, the quality of the ideal concrete is related to the compressive strength; second, the compression test of concrete is more economical than other tests. simple. The largest aggregate specification is a 1 1/2 hour (3.8 cm) ordinary concrete test piece with a cube of 6 o’clock (15.2 cm). When the aggregate size is less than 3/4 (1.9 cm), 4 o’clock can be used. (10 cm) cube. The size of the specimen has some influence on the compressive strength obtained, and the smaller specimen gives a higher strength. For example 4 o’clock (10 centimeters)
