Use of high-strength non-shrinkage grouting material in liaoning province is introduced

Liaoning high-strength non-shrink grout material 1, [ Preface] Liaoning region using high-strength non-shrink grout material is a new type of secondary grouting material, much as light gray powder granular materials, early strength, high strength, large liquidity and micro expansion without shrinkage. Mainly used in machinery and equipment installation of the pulp and secondary grouting, the retaining bolt anchorage, and repair of defective parts of the buildings or structures, emergency reinforcement and reinforcement, the seam floor and filling and repair scrambling to engineering, etc. Alternative similar imported products to meet the large machinery and equipment installation of high precision and high quality requirements. The product price is low, easy to use, is an ideal new grouting material. Inorganic cementitious materials, grouting materials as a new type of reinforcement products, not only has convenient construction, small working face, the characteristics of high efficiency, but also has strong adaptability, wide applicable scope, the overall performance of the anchorage structure is good, price is low wait for an advantage. Because of equipment foundation anchor have don't have a large number of digging holes, but only in the concrete base parts of drilling equipment, use of high-strength non-shrink grout material as reinforced or foundation anchor bolts and concrete bonding the seam an agent can ensure good bonding with concrete, so as to reduce the damage in the existing concrete structures and also reduces the installation of quantities. High-strength non-shrinkage grouting material for reinforcement and fixed equipment in bolt anchorage effect is to rely on and the base material of swelling pressure and friction force, the use of the anchoring force of its own adhesive material, reinforced and bolt bar and concrete substrate anchoring together effectively, the bonding strength and mechanical bite to withstand the load, when the anchoring the depth of the reinforcing steel bar to meet the design or bolt, has a strong pulling force, thus ensuring the anchoring strength. Inorganic cementitious materials grouting material in shenyang marriott hotel stairs strengthening, reconstruction of KFC, dandong city &qingdao reinforcement, anshan applied in equipment installation and other projects, by the user's consistent high praise. Engineering practice shows that high strength non-shrinkage grouting material of this new type of secondary grouting material is a kind of processing equipment, construction and material for the concrete bridge structure defects repair. This will be reinforced, bolts and other solid buried in the concrete base material of high-strength non-shrink grout material, recent decades have been widely used in all types of building construction industry renovation and maintenance, reinforcement, has been widely used in industrial enterprises equipment foundation installation. In the current application of high-strength non-shrink grout material reinforcement and reconstruction engineering, concrete construction method according to the operating methods of the manufacturers to provide all the construction. Construction procedures are guided by the manufacturer, high-strength non-shrink grout material all materials are provided by the manufacturer. 2, high-strength non-shrink grout material product features: design flexibility: according to the need can be found in most of the reinforced concrete structures plane position, according to the structure characteristics and the number of planting bar design and specifications. Equipment foundation installation design, can completely meet the requirements of construction equipment installation drawing. Early strength, high strength, initial set > 2 hours, the final set < 10 hours. High early strength, especially in the 1 and 3 days high strength. One day strength up to more than 30 mpa, equipment installation can run after a day of production. Technology is simple, can greatly shorten the construction period, often in 2 ~ 3 days or more in a short period of time to repair the defects can be put into use. Their state: the scene just according to the instruction after adding water mixing, direct injection equipment foundation, without vibration can fill all equipment foundation clearance. Micro expansion: can produce moderate inflation, close contact to ensure that the equipment base and foundation, without shrinkage between base and foundation. High durability: oil, water penetration resistance is strong, antifreeze performance is good. Reliability is better than that of embedded parts: general reinforced concrete structure in the need to connect with other structures or equipment, the joint should be reserved embedded parts, but the embedded object position is not easy to determine, after concrete pouring forming embedded parts difficult to change the position of trival, and construction and high-strength non-shrink grout material has certain flexibility, reliability and embedded parts are basically the same. New concrete structure basic didn't slip. Building technology co. , LTD. , has been renamed as group, has a factory in 2015 to invest in changchun, CGM high-strength non-shrinkage grouting material in sales is expected to reach 10000 tons · · · · · ·
