本文究究了圆柱体试件尺寸及养护条件对所测定的不同强度砼的抗压强度的影响,采用了三批设计强度分别为35MPa、90MPa及120MPa的预拌砼。将直径为100mm、150mm、200mm的圆柱体试件分别放在空气中,密封、水中养护。 从试验结果可见,防止水份散失和水中养护方法对强度有利。随着圆柱体试件的尺寸降低,其强度明显增加。本文给出了所研究的普通砼、高强砼、越高强砼在不同养护条件下及不同圆柱体试件尺寸的强度增长关
In this paper, the influence of the dimensions and curing conditions of the cylindrical specimen on the measured compressive strength of different strength thorium were studied. Three batches of premixed ramming concrete with design strengths of 35MPa, 90MPa and 120MPa were used. The cylindrical specimens with diameters of 100mm, 150mm, and 200mm were placed in air, sealed and maintained in water. From the test results, it can be seen that preventing water loss and water conservation methods are beneficial to strength. With the decrease of the size of the cylindrical test piece, its strength increases significantly. In this paper, the strength growth of the test specimens under different curing conditions and different cylindrical specimen dimensions is studied.
