Mechanical Properties of Hybrid Fiber Reinforced Rubber Concrete.

Based on the variance analysis of the compressive strength, splitting tensile strength and flexural strength of HFRC in Table 6 , it can be seen that V BF is an extremely significant factor affecting the three strengths of HFRC; V PF has a certain impact on the compressive strength of HFRC and V PF represents non-significant factors affecting the splitting tensile strength and flexural strength of HFRC; V R is a significant factor affecting the compressive strength of HFRC, and the impact on the splitting tensile strength and flexural strength of HFRC is relatively close.

With the increase of V R , the compressive strength of HFRC gradually decreased, the splitting tensile strength and flexural strength showed a trend of first increasing and then decreasing; when V R increased from 5% to 10%, the splitting tensile strength and flexural strength of HFRC increased by 1.03% and 0.61%, respectively; when V R increased from 5% to 15%, the compressive strength, splitting tensile strength and flexural strength of HFRC decreased by 5.98%, 6.48% and 4.69%, respectively. 3.3.
