摘要
进行了高温前后纤维高性能混凝土抗压强度与抗弯性能试验。试验结果表明,纤维可降低高温对混凝土抗压强度的影响,钢纤维能显著提高混凝土的弯曲韧性。与单掺钢纤维的混凝土相比,玻璃纤维对高温后混凝土力学性能的改善程度比较有限,混杂纤维混凝土具有等效或更出色的高温前后力学性能。
The compressive strength and flexural properties of fiber reinforced high performance concrete before and after high temperatures are tested.The results show that fiber can decrease the effects of temperature on compressive strength of concrete,and steel fiber can obviously improve the flexural toughness of concrete.Compared with the concrete just adding steel fiber,the improving degree of mechanical properties of concrete after high temperature is limited by glass fiber.Hybrid fiber reinforced concrete has the same or even better mechanical properties before and after high temperatures.
