废弃胶合木纤维混凝土力学性能试验研究

Experimental Study on Mechanical Properties of Waste Glulam Fiber Concrete

本文研究了废弃胶合木纤维不同的含量对混凝土抗压强度和抗劈裂强度的影响。经过28天的养护,废弃胶合木纤维混凝土中废弃胶合木纤维的掺量为0%、1%、3%、5%、7%,其研究结果表明,废弃胶合木纤维混凝土随着掺入量的增多,抗压强度呈缓慢降低的趋势,而抗劈裂强度呈先上升后下降的趋势。表明了废弃胶合木纤维对混凝土的抗裂性有一定的提升。

The effects of different content of waste glulam fiber on compressive strength and cracking strength of concrete were studied. After 28 days of maintenance, the content of waste glulam fiber in waste glulam fiber concrete is 0%, 1%, 3%, 5%, 7%. The research results show that with the increase of the amount of waste glulam fiber concrete, the compressive strength of waste glulam fiber concrete shows a slow decrease trend, while the anti-splitting strength increases first and then decreases. The results show that the waste glulam fiber can improve the crack resistance of concrete to some extent.
