Description
Technical Field
The invention belongs to the technical field of terrace materials, and particularly relates to an ultra-high performance concrete non-slip ramp.
Background
In recent years, a large number of organic resin anti-slip ramps are used in various parking lot ramp-up and ramp-down places, and the ramps are bright in color, free of obvious vibration during vehicle running and good in pressure resistance and wear resistance. However, the organic material has poor durability, the expansion and contraction coefficients of the organic material and the ramp substrate inorganic material-concrete are not consistent, and the organic material is easy to fall off after being used for 5 to 10 years, so that the driving comfort and the ramp appearance are influenced, and the driving safety is influenced even when the organic material falls off in a large area in a wet ground state on rainy days.
The ultra-high performance concrete has the durability of ultra-high impermeability, freeze thawing resistance, corrosion resistance, high temperature resistance, impact abrasion resistance and the like. It can be more than 200 years in corrosive environments (such as marine environments); can be used in non-corrosive environment (such as city building) for 1000 years. The relatively conservative japanese guidelines suggest that the design working life of ultra-high performance concrete under normal circumstances is 100 years. The service life of the slip-limiting ramp prepared by the ultra-high performance concrete is at least 100 years, which is 10-20 times of that of the common organic resin slip-limiting ramp on the market at present. In addition, the ultra-high performance concrete as an inorganic material can be recycled after the service life is over, the pollution in the production and manufacturing process is far less than that of an organic resin material, the maintenance cost of the ultra-high performance concrete used in a ramp is far lower than that of the organic resin material, and the ultra-high performance concrete is an environment-friendly energy-saving material.
