Effect of glass fiber length on the properties of high strength self-compacting mortar
High strength concrete and/or mortar is known as more brittle in comparison with conventional concrete, which in turn limits the application of such material into practical engineering. The brittleness of concrete can be relieved by using dispersed fibers (steel, glass, synthetic, and natural). Thus...

| Tóm tắt: | High strength concrete and/or mortar is known as more brittle in comparison with conventional concrete, which in turn limits the application of such material into practical engineering. The brittleness of concrete can be relieved by using dispersed fibers (steel, glass, synthetic, and natural). Thus, in this paper, the authors studied the effect of glass fiber length on the properties of high strength self-compacting mortar at both the fresh and hardened state. The experimental results have shown that the higher glass fiber length, the lower the resultant slump flow of Self-Compacting Mortar (SCM) mixture. At the hardened state, fiber length does not affect the compressive strength of SCM. However, the higher the fiber length was added, the higher the flexural, and the splitting tensile strength could be observed. In terms of durable properties such as waterproof grade and abrasion resistance,
fiber length does not influence on these properties. The outcomes of this research are useful for further study on the application of high strength SCM with glass fiber for the rehabilitation of hydraulic structure in general and marine structure in particular. |
