纤维增强材料对菱镁水泥制品的影响

摘要

近几年，以菱镁水泥为主材的制品得到越来越多的应用，而菱镁水泥硬化体是一种气硬性脆性材料，有耐冲击性能差等缺点。本文通过制品中添加纤维来增强材料强度，试验发现，短切玻璃纤维和长切玻璃纤维共同复合能够对菱镁制品的抗折强度和抗压强度较大提高。%Products based on magnesite cement materials were more and more applied in recent years , however magnesite cement is brittle materials after solidification which has the advantage of lower impact resistance .In this paper, the fiber is utilized to enhance the strength of the material .In the experiment ,we found short glass fibers and long glass fibers composite can be greatly improved the flexural strength and compressive strength of the magnesite products .
