Grouting material beauty antifreeze agent scope of application and matters needing attention

grouting grouting material antifreeze beautiful seam an agent of secondary grouting material antifreeze beautiful seam an agent grouting material in engineering can adopt the following antifreeze seam an agent. A, 1, chlorine salts electrolyte inorganic salts with chlorine salt as antifreeze component plus the seam an agent. 2, the resistance to chlorine salt class rust and rust resistance to chlorine salt group is divided into antifreeze component plus the seam an agent. 3, no chlorine salts with nitrite, nitrate and other inorganic salt as antifreeze component plus the seam an agent. Second, water soluble organic compounds in some alcohol and other organic compounds for antifreeze component plus the seam an agent. Three, organic compound and inorganic compound class four, composite antifreezing seam an agent with composite early strength antifreeze component, air-entraining plus the seam an agent, water reducing and other components. Anti-freezing type grouting material scope 1, antifreeze containing strong electrolyte inorganic salt seam an agent used in grouting guess, have to agree with related regulations. 2, containing nitrite, carbonate antifreeze beautiful seam an agent used for prestressed grouting material structure is prohibited. 3, containing nitrite harmful ingredients such as antifreeze beautiful seam an agent, banned for drinking water engineering and in touch with food, eating is prohibited. 4, containing ammonium nitrate, urea etc excitant odour of antifreeze seam an agent, ban for work, residential construction project such as 5, strong electrolyte inorganic salt antifreezing seam an agent and its dosage should fit the rules. 6, organic compound anti-freezing beautiful seam an agent can be used for grouting material, reinforced prestressed grouting materials and grouting engineering. 7, organic compound and inorganic compound anti-freezing beautiful seam an agent and compound anti-freezing beautiful seam an agent can be used in grouting material, reinforced prestressed grouting materials and grouting engineering, and with the relevant provisions. 8, on the hydraulic, Bridges and freezing-thawing resisting requirements of grouting material has a special project, should be determined by test anti-freezing type and dosage of the seam an agent. Completes the grouting material ratio of antifreeze beautiful seam an agent, selection, test, the escort for winter construction, building materials have been trying to.
