Henan zhengzhou CGM - A general-purpose high-strength non-shrink grout material manufacturers

CGM - A general-purpose high-strength non-shrink grout material CGM - 1 universal high-strength non-shrink grout material is a kind of economic and practical products, compressive strength, fluidity, etc all can reach the cement grouting material application technical specifications ( GB / T50448 - 2015). Class III standard products, mainly used in 80 ~ 200 mm thickness of grouting layer, bolt hole wall and the surface net spacing of 15 ~ 100 mm of all kinds of engineering secondary grouting, as well as the surface of the concrete column and steel set minimum spacing not less than 20 mm reinforcement, etc. The product on the premise of meet the needs of the project can reduce the engineering cost. The technical performance indicators technical requirements for the county of material particle size ( mm） ≤4. 75 fluidity ( mm） The initial value of 290 or higher 30 min retention value of 260 or more vertical expansion ratio ( %） 3 h 0。 1 - 3. The expansion of the 24 h and 3 h 5 difference between 0. 02 - 0. The compressive strength (5 MPa） 1 d and 3 d or 45 or 28 d p 65 without the action of the reinforcement rustily exudation rate ( %） 0 CGM - 1 eight characteristics general-purpose high-strength non-shrink grout material 1, early strength, high strength: 1 - Compressive strength of 30-3 days More than 50 mpa, equipment installation can run after a day of production. 2, since the flow: the scene only after adding water mixing, direct injection equipment foundation, does not need vibrating can fill all voids of equipment foundation. 3, micro expansion expansion: to ensure that equipment and close contact between foundation, without shrinkage casting body to ensure the long-term safe operation of the equipment. 4, no rust role: no harm of corrosion on steel bar, steel plate, etc. 5, oil resistance, permeability: soak 30 days after its strength in the oil by more than 10% higher than that of before the oiled. 6, long resistance: 2 million times of fatigue experiment, 50 times of freeze-thaw cycle test intensity has no obvious change. 7, good weather resistance: - 40 ℃ ~ 600 ℃ safe use for a long time. 8, anti stripping: strong interface combination between the old and the new. CGM - Universal high-strength non-shrink grout material USES 1, equipment installation of secondary grouting 2, 3, all kinds of steel column base installation grouting machine electrical equipment shim installation flow without grouting, anchor bolt anchoring plinth 4 5, frame structure joints grouting batholith grouting anchor reinforcement reinforcement, bridge joint grouting in the next 6, post-tensioned prefabricated grouting, prestressed concrete bridge crack seal 7, wall body and foundation beam slab column repair and renovation of grouting reference usage: reference volume calculation in 2. 28 ~ 2. Based on 4 tons per cubic meters, the actual usage. Refer to add water: water added reference calculation with grouting material proportion of 12. 5% of water mixing. According to the standard: GB / 50448 - 2008 'cement grouting material technical specification for application of standard technical indicators. Packaging stored: 1, the grouting material for 50 kg/bag, store in ventilated dry place and avoid direct sunlight. 2, shelf life is 6 months, beyond the guarantee period shall be the re-inspection qualified rear can use. Our company long-term wholesale produce series of grouting material is as follows: CGM - Universal grouting material CGM - 1 Type 2 pisolite grouting material CGM - 3 type ultrafine CGM grout material - Super early strength type grouting material CGM - 4 A high-strength non-shrink grout material CGM - 340 Non-shrink grout material H - epoxy High-strength non-shrink grout material H - 40 type 60 type high-strength non-shrinkage grouting material
