摘要

For normal strength concrete, it has been found that direct tensile strength could be satisfactorily predicted from 8 % to 12 % of the compressive strength value and is often estimated as 0.4 to 0.7 times the square root of the compressive strength. Splitting tensile strength is estimated from 8 % to 14 % of the compressive strength. For ordinary strength concrete also, it has been found that tensile strength obtained by double-punch test is slightly lower than the tensile strength obtained by split test. Contrary to the ordinary concrete there is no background information for evaluating the two-stage concrete tensile strength by double-punch and split tests. This study proposes an empirical approach for predicting the tensile strength from the compressive strength of two-stage concrete. This paper presents the results of experimental tests of the tensile strength of two-stage concrete measured by double-punch and split tests of one type of stone aggregate and different mix proportions of grout. On the basis of these results a relationship between the tensile strength and the compressive strength of two-stage concrete is statistically elaborated.
