Finally know what is secondary epoxy grout technology principle, finally see today

Cement filling material is also called the second epoxy grout, mainly including inorganic second epoxy grout, organic polymer secondary epoxy grout and composite epoxy grout. Cement base secondary grout is a kind of one-component epoxy cement base material, fluid under gravity and electrochemical principle, can improve the bearing capacity of structure system, prevent the leakage, repair cracks, improve the overall physical conduction effect of structural system, such as pore flow and injection, the reserved pore or heterogeneous interface, etc. At present, the implementation of the standard JC/T 986, GB/T 50448, GB50550, JG/T 408, etc. Finally know what is secondary epoxy grout technology principle, today finally understand: secondary epoxy grout is a kind of excellent building material, its main features are: 1 is the main materials, fine aggregate and cement chemical agent. 2 liquid, early strength, high strength and swelling. Three vertical expansion rate is 0. 12≤3. 5%. Cement, micro-nano packing b, silicon powder such as c, expansive agent, water reducing agent d e is vertical expansion rate of cement strength, liquidity and important indicators, the adhesive of the table 1 under the conditions of the chemical composition, the following figure shows the factors that affect cement hydration index of technical effect, by promoting CS3 hydration process, inhibition of cement CSH late contraction, change the cement hydration surface Zeta potential, specimen of the new water grouting, high strength and volume stability. Inflation control agent, E is the core of the suppression and compensation shrinkage material under the different expansion control mechanism, by analyzing the expansion volume curve and time curve, analyzes the four kinds of expansion agent A, B, C and D, to eliminate in the process of grouting volume shrinkage cracking of plastic shrinkage and 3 days later. In practical engineering, the quadratic epoxy grout cement is a kind of one-component & quot; Fine & quot; Building materials, and finally know what is secondary epoxy grout technology principle, today finally understand the content of raw materials and environmental fluctuations can cause grouting casting process parameters of a chain reaction, so the single performance adjustment need to redesign the overall function of the grouting, thus engineering complexity and the precision of the building materials are mutually dependent and restriction, in terms of construction, construction environment humidity, low temperature, airtight, moisture evaporates slow, easy to cause setting time is long, supporting and assembly is not scientific, easy to cause in the field of volume shrinkage and cracks.
