为了考察用于水泥混凝土工程纤维的稳定性,模拟水泥水化的碱性环境,研究3种不同纤维在不同温度的碱性条件下的化学结构稳定性和力学性能的变化,分别采用纤维表面微观形貌和单纤维断裂强力来进行表征。
In order to investigate the stability of the fiber used in cement concrete engineering and to simulate the alkaline environment of cement hydration, the chemical structure stability and mechanical properties of three kinds of fibers under alkaline conditions at different temperatures were studied. Morphology and single fiber fracture strength to characterize.
