Luliang grouting material - expansion agent application techniques 
 1, FEA the expanders's content. FEA recommendation dosage is 8 percent, reinforcing band or poured with 10%; minimum unilateral grouting material within the content of 35kg, the maximum dosage for a 50kg; for water requirements compensate for shrinkage grouting material, cement and FEA in png two least 320kg/m3; when the dosage should be determined according to the percentage of FEA can be the same amount of replacement of cement with fly ash share, it should be seen as cementing material content in the calculation of the FEA. 
 C3S, low C3A Portland cement, when of SO3 regional 1.8% of FEA content should be properly: Use a high of C3A, high SO3 content in cement, the dosage may be appropriate to reduce the 
 For foreign powers grout, horizontal reinforcement ratio should 0.4% to 0.6%, the level of steel can be used 10mm ~ 16mm reinforced, spaced not more than 150mm. In addition, from the restrictions on the form of shrinkage-compensating effect in accordance with three, two-way, one-way diminishing. Solid thickness is greater than 100mm of the floor, the top should also configure the crack resistance of reinforced, so that the upper part of the grouting material, the Luliang grouting material may be only in the state of the reinforced constraints. 
 3, seamless construction of the grouting material, Luliang grouting material works to strengthen the band set up shall be paid to the characteristics of the structure size, such as length, width, area, shape, thickness, and requirements to strengthen the horizontal direction with the temperature reinforcement than reinforcement ratio 10% ~ 15% increase in strength grade on both sides to improve 5MPa. 
 4, beam, slab, column grouting material at the same time pouring the best use of the second vibrator to avoid settlement cracks because of the large slump generated; pumping the grouting material, Luliang grouting material after the completion of the pouring surface pressure rub to prevent cracking due to excessive water loss. 
 Timely moisture conservation, to ensure water supply in order to promote the full formation of expansive ettringite. Large volume floor to water storage conservation is appropriate; wall, appropriate to the porous tube from the top surface watering conservation; also can be used to cover the wet grass grid; water to keep the effect is generally better than spraying the conservation of liquid way . Winter construction, but also for heat conservation. 
 Luliang grouting material scope of application: 
 Jade wall "brand the Luliang grouting material is mainly used for: anchor bolt, runway repair, nuclear power equipment fixed, the reinforcement of road and bridge engineering, machine base, the steel structure and foundations pregnant population, the device based on secondary grouting plant buried steel bars, and crack control of reinforced concrete structure and transformation of the old concrete structure, mechanical and electrical equipment installation, rail and steel structure installation, the static pile seal pile, the thickening of the wall structure and the drain water leakage repair, a variety of collapse grouting of the foundation works and repair works.
