Product Description high-strength micro-expansion is a cement-based grouting material micro-expansion material, has good mobility, micro-expansion, early strength, high strength and resistance to oil permeability. Series products are widely used in metallurgy, electric power, petrochemical, chemical, light industry, machinery and equipment, fixed installation bolt grouting and building beams, slabs, columns and floor of reinforcement such as grouting. Superior product overall performance, ensure adequate space is filled at the time of grouting, and provide the appropriate expansion stress, ensure that equipment installation location, structure repair or planted Reinforcement in a day or even a short time, shorten the construction period, to save labor, time, or early morning operation carried technical and economic results. Micro-expansion of high-strength grout Main features: easy construction: bagged products can be used on-site mixing with water; high flow regime: product has excellent artesian performance without vibration to fill all space; early strength: 24 hours after grouting meet the needs of the fastening bolts, boot commissioning; high strength: the ultimate high strength to meet all kinds of equipment installation and repair and strengthening of requirements; micro-expansion: no shrinkage after filling, to ensure close contact between the device and the foundation bolts; no rust Role: for steel, bolts, steel and other non-corrosion damage; anti-oil: soak in the oil for 28 days without loss of strength; heat shock: After planting steel bars allow for flame cutting and welding operations; be winter construction: Allow - conducted at 15 ℃ temperature outdoor grouting; Packaging: The product is paper-plastic bag lined with plastic bags; Storage and Shelf Life: Store in a dry and ventilated room to the shelf life of six months. Scope 1, equipment foundations and secondary grouting board foot steel column (see Table I) 2, anchor bolts filling (see Table II) 3, reinforced concrete structure filling: ① increasing section and Reinforcing steel column ( concrete columns) cup filling choice AGM-270IV products; ② Reinforcing steel cover first with AGM3801 (superfluid), AGM340II products (according to the wall plate and column spacing). 4, post-tensioned concrete structures pore filling choice AGM-380I (superfluid) grout. 5, winter construction grouting ambient temperature of -15 ~ 5 ℃, should adopt AGM-340II (winter construction type), AGM-290III (winter construction type), AGM-270IV (winter construction type) grout. 6, part of a long-term equipment filling in a hot environment, following irradiation temperature 500 ℃, can AGM-290III (heat-resistant) grout.
