Steel rust resistance the seam an agent to the importance of early strength grouting material? - Hou resistance of CGM grout material

CGM grout CGM grout material manufacturer CGM grout material price add reinforcement rust resistance the seam an agent is inhibited or prevent early strength of grouting reinforcement corrosion in the main, the most convenient and most simple measures. Among the various rust resistance performance evaluation method, electrochemical synthesis experiment method is one of the most basic, the most commonly used method. Early strength of grouting material in the reinforced steel corrosion has become the main factors of early strength grouting material structure durability. A variety of environmental conditions ( Such as carbonation, chloride ion erosion, etc. ) Can make the steel surface has been formed in the early strength grouting material passivation film losing its protective function, prompting of reinforcement corrosion. Due to reinforcement corrosion will make the early strength of grouting material original effective reinforcement ratio is reduced, the early strength grouting material structure there is a danger, at the same time because the surface of the steel bar corrosion layer become rust after volume increased, its expansion stress makes early strength grouting material protective layer cracking, drum, peeling, further leakage reinforcing bar corrosion, gradually increase the early strength of grouting material structure, easy to cause component suddenly broken crack grouting material curing period and sudden accident. For offshore engineering, Bridges, parking lots, chemical plant and other steel early strength grouting material structure, the phenomenon is particularly prominent. How to suppress early strength jung liquid grouting material with steel interface in the cathode and anode electrochemical etching, reduce the corrosion rate of steel, reduce the structural damage due to reinforcement corrosion in changchun, has become a worldwide problem. Steel rust resistance and evaluation technology has become) pulp reinforced high early strength of grouting material durability research key technology. How to inhibit corrosion? Adding early strength grouting material reinforcing steel bar rust resistance beauty seam an agent is delay the early strength of reinforcement corrosion problems in the grouting material is one of the most important technical means, also is one of the most convenient and easy way of rebar rust resistance.
