Js-hg seawater corrosion inhibitor for use

  Js-hg seawater corrosion inhibitor is a composite additive, which meets the requirements of gb6566 radionuclides in building materials and jtj275 technical code for corrosion protection of concrete structures of seaport engineering& emsp;& emsp; It has excellent crack resistance and water impermeability when properly mixed into the concrete of the seaport
By improving the compactness of the concrete to resist chloride corrosion, it can prevent or slow sulfate and chloride corrosion from the fundamental reaction mechanism, so as to improve the durability of the concrete, which is to solve the problems of harmful cracks caused by dry shrinkage and cold shrinkage of the concrete, leading to chloride ion penetration, seawater erosion and so on, Materials to improve the durability of concrete structures in seaport projects

Scope of application
 & emsp; 1
Js-hg can play five roles: self waterproofing of structure, seamless construction of super long structure, crack control of mass concrete, prevention of chloride ion penetration, seawater erosion resistance and sulfate erosion resistance

2
Marine concrete structures or parts in direct contact with seawater, such as wharf, berm, offshore oil drilling platform, sea crossing bridge pier, water conveyance channel, etc

3
Anti crack and anti-seepage concrete can be used in basements in coastal areas and buildings with waterproof and anti-corrosion requirements
Such as basement, subway, tunnel, etc

4
The preparation of shrinkage compensating concrete can be used in marine mass concrete structures and mass projects requiring less expansion joints

5
Infrastructure engineering in saline alkali areas
Such as pile foundation, basement, highway, railway foundation, etc

6
Reservoirs, storage tanks, cooling towers and other projects with corrosive media and high requirements for impermeability
