Method for proportioning and constructing anti-freezing concrete below ice surface of ice rink of speed skating stadium

Abstract

The invention discloses a method for proportioning and constructing anti-freezing concrete below an ice surface of an ice rink of a speed skating stadium. The method comprises a specific proportioning method for the anti-freezing concrete, a method for detecting the gas content detection quality of the anti-freezing concrete, a concrete flattening and leveling method, a method for detecting the flatness after polishing is finished, a method for arranging a contraction joint of the ice rink and a method for arranging an expansion joint in the middle of the anti-freezing concrete below the ice surface of the ice rink of the speed skating stadium. According to the method for proportioning and constructing the anti-freezing concrete below the ice surface of the ice rink of the speed skating stadium, which is provided by the invention, the concrete has excellent endurance performances such as cracking resistance, permeation resistance and freeze thawing resistance and excellent mechanical and deformation performances such as splitting tension, contraction, ultimate extension and toughness.

Description

technical field [0001] The invention relates to a concrete proportion and a construction method, in particular to a frost-resistant concrete proportion and a construction method under the ice surface of an ice rink in a speed skating hall. Background technique [0002] In the construction of the speed skating hall, the concrete's crack resistance, impermeability, and freeze-thaw resistance are key indicators in the construction. In the existing technology, the concrete pavement of speed skating rinks is generally prone to freeze-thaw damage, which seriously affects the service life of the pavement, correspondingly increases the maintenance cost of the venue, and poses a hidden danger to the safety of skating. Aiming at the defect that the concrete pavement of the ice rink is prone to freeze-thaw damage in the prior art, the present invention proposes a antifreeze concrete proportioning and construction method different from the prior art under the ice surface of the ice rink...
