CGM grout material why carbide

CGM grout material why do you want to know why CGM grout material carbide carbide, we can learn what is the main components of the grouting material! Grouting material of carbide is concrete grouting materials by a chemical corrosion. CO2 gas in the air penetration into concrete, and its basic substances react after form carbonates and water, bring down the alkalinity of concrete process known as concrete carbonization, also known as neutralization, the chemical reaction is: Ca ( 哦) 2+CO2=CaCO3+H2O. Generated a lot of calcium hydroxide in the hydration process of cement to make concrete grouting material gap filled with full of calcium hydroxide solution, in the alkaline medium has the outstanding maintenance effect on the reinforcement, the generation of refractory steel appearance of Fe2O3 and Fe3O4, called passivation membrane. Carbide decreased alkalinity of concrete grouting material, after when the carbide beyond the maintenance of concrete grouting material layer, in the presence of water and air, makes the maintenance effect of reinforced concrete grouting material lost and reinforced began to rust. Visible, concrete carbonation effect usually do not directly responsible for its functional degradation, about the plain concrete, the effect of concrete durability, carbide and progress but about reinforced concrete grouting material, can reduce the alkalinity of concrete, carbide, add the number of hydrogen ions in concrete pore solution, which can make the maintenance of concrete in reinforced effect weakened.
