- Abstract:
- This article gives the test results of the glass fiber concrete manhole cover under the action of vertical load on the basis of the basic mechanical performance test of glass fiber enhancement cement (concrete) basic mechanical performance test. The test research shows that the cracking load of the glass fiber concrete manhole cover with reasonable process and ratio of the proportion is significantly delayed. Higher ability, good delay, and good toughness and energy absorption. The two -year -old glass fiber concrete manhole cover of glass fiber covering shows that the manhole cover made by this method can meet the requirements of various types of vehicle loads at all levels of roads in the city, and the price is cheaper, with obvious socio -economic benefits.
