Steel fiber reinforced concrete (SFRC) has played an important role in urban construction, and its advantages have been recognized by everyone. It is necessary for the roadbed to have the characteristics of strong compression resistance, which happens to be the characteristic of fibers, so it is widely used in the pavement of doorways. With the continuous development of shopping malls and progress. Its important functions include tensile strength and bond strength. Fiber plays an increasingly important role in the layout of Engineering settings. It is also widely used in concrete. In reality, it is also seen that fiber plays an important role in concrete.
若采用钢纤维混凝土进行罩面修复,则一次性投资的费用比近年重建混凝土路面要节省许多。同样,从一次性投资、使用年限、维修费用、资金的时间价值来全面评价纤维混凝土路面工程的经济效益,与新铺沥青混凝土路面评价综合效益,纤维混凝土路面虽一次性投资较前者高,但从其维修费用、使用年限的不同考虑,以及和资金的时间效益,用年成本法计算其等值年金,结果表明纤维混凝土路面每年支出的费用比沥青混土路面要低35%。采用纤维混凝土修补法,不但可使钢纤维混凝土的质量及其增强效果得到保证,而且还可提前开放交通,具有显着的经济效益和社会效益。
If steel fiber reinforced concrete is used to repair the overlay, the cost of one-time investment will be much less than that of rebuilding concrete pavement in recent years. Similarly, from one-time investment, service life, maintenance cost and the time value of funds to evaluate the economic benefits of fiber reinforced concrete pavement engineering comprehensively, and from the new asphalt www.changzhibanjia.cnwww.baodingbaojie.com.cnwww.yfpackaging.com.cnwww.diteLi.com.cn
www.lantianr.cnwww.ktmfj.cnconcrete pavement evaluation of comprehensive benefits, although the one-time investment of fiber reinforced concrete pavement is higher than the former, but from the different considerations of its maintenance cost, service life, and the time benefit of funds, the annual cost method is used to calculate it. The results show that the annual expenditure of fiber reinforced concrete pavement is 35% lower than that of asphalt concrete pavement. The use of fiber reinforced concrete repair method can not only ensure the quality of steel fiber reinforced concrete and its reinforcement effect, but also open the traffic ahead of time, with remarkable economic and social benefits.
