纤维增强表面玻璃化膨胀珍珠岩保温板的力学性能试验研究
Experimental study on mechanical properties of fiber reinforced insulation board with surface-vitrified and expanded perlite
摘要
Abstract
Due to relatively low tensile strength,the insulation board with surface-vitrified and expanded perlite is prone to fatigue failure under the reciprocating action of horizontal load,which limits its market application.In order to solve this problem,the activated blast furnace slag powder,instead of cement,was used as inorganic cementing material.Under the joint action of other functional additives,the insula-tion board with surface-vitrified and expanded perlite was prepared,and the mechanical properties were tested.By adding organic fibers(polypropylene and polyester)with good flexibility and high strength,flexural strength and deflection of specimens with different fiber content were tested,and load-deflection curves were drawn.The test results show that the fiber can improve the bending strength and toughness of the surface glass expanded perlite insulation board,but the bending strength is lower than the toughness increase,and the strengthening effect of polyester is significantly better than that of polypropylene.When the optimal polyester content is 0.8%,the bending strength increases to 0.53 MPa,the toughness im-proves by 202%,and the toughness index reaches 4.21.The comprehensive performance of the board exceeds the current national standards,and the material is environmentally friendly.关键词
