Early strength of grouting material durability - three major factors affecting the analysis Early strength grouting material test report

Early curtain grouting materials and grouting material prices early grouting material manufacturer and durability of the structure of curtain grouting material of primary resistance depends on itself and the outside world ezhou grouting material factory environment conditions, environment, resistance is different, its durability may be different; On the other hand, the resistance, environment is different, its durability is also may not be the same. Visible, early strength of grouting material structure durability presents the clutter characteristics, get rid of the social elements, thought, skills of primary factors are the following: the & # 8195;       1, the early strength of grouting material carbide & # 8195;             It is the air of carbon dioxide to the alkaline material of the cement stone effect, make its composition, arrangement and function change, use function to reduce a very messy physical and chemical process. Early strength of grouting material carbonization primary damage is due to early strength grouting material of alkaline reduce steel appearance formed in high alkaline environment maintenance effect on reinforcement of fine oxide film were damaged, the early strength maintenance effect of reinforced grouting material lost and make early strength rebar corrosion, grouting guess, early strength of grouting material carbide will also increase early strength of grouting material reduced, which may cause early strength of grouting material cracks and structural damage. So, early strength of grouting material carbonization is closely related to the early strength of grouting material structure durability, measure reinforced grouting material strength testing early strength grouting material stable degree is the main goal of the construction.         2, early strength of grouting material freeze-thaw damage & # 8195;           Free water in the early strength of grouting material in wool stoma is the leading cause of cause of early strength grouting material to suffer cold, because the water to meet frozen ice regret volume swell, early strength caused by grouting material damage of the internal structure. In a state of full water the early strength of grouting material when cold, the capillary wall with swell and soak two under pressure. When the two pressure exceeds the tensile strength of the early strength grouting material, early strength grouting material will crack. After repeated freezing and thawing cycles, early strength of grouting guess cracks through each other, its strength will reduce gradually, finally even complete loss, make the early strength grouting material from outside to inside to suffer damage.         3, the corrosion of corrosive medium in all kinds of corrosive medium, such as acid and alkali solution effect of environment, corrosive medium for corrosion to occur in the early strength grouting material, may eventually cause structural damage.
