Problems solved by technology

Cl- passes through the concrete protective layer and when the concentration accumulated on the surface of the steel bar exceeds a certain range, the passivation film of the steel bar will be destroyed, causing the steel bar to corrode and expand, resulting in the destruction of the concrete structure, while the ordinary concrete anti-wave block in the ocean When used in environments such as rivers and rivers, it will be affected by various natural factors such as freezing, wind and waves, water quality, and tides, and its service life will be shortened.

Abstract

The invention discloses a washplate material, which is characterized in that: the invention comprises: a. cement 1 weight part; b. water 0.5 to 1.0 weight part; c. steel slag 0.5 to 10.0 weight part; d. steel slag powder 0.05 to 0.35 weight part. Comparing with the common concrete produced washplate, the invention has advantages on ati-pressure intensity, anti-shock performance, resistance to freezing and thawing and anti-bending intensity.

Description

technical field [0001] The invention relates to a material for anti-wave blocks and a production method thereof. Background technique [0002] In environments such as oceans and rivers, concrete structures are easily damaged, and the main causes of damage are steel corrosion and salt corrosion, and Cl is the dominant ion that causes steel corrosion. - . Due to Cl - The ionic radius is very small, and its migration ability in concrete is strong. Cl - Passing through the concrete protective layer, when the concentration accumulated on the surface of the steel bar exceeds a certain range, the passivation film of the steel bar will be damaged, causing the steel bar to corrode and expand, resulting in the destruction of the concrete structure. Freezing, wind and waves, water quality, tide and many other natural factors will shorten its service life. [0003] With the increase of my country's steel production year by year, the discharge of steel slag has also increased. A lar...
