AUK-G02 Grouting material
Grouting material is based on high-strength materials as aggregate, cement as a binder, formulated by high fluidity, micro- expansion, anti-segregation and other substances. A certain amount of water is added to the construction site, and it can be used after mixing. Grouting material has good liquidity, fast hardening, early strength, high strength, no shrinkage and micro expansion. It is harmless, anti-aging, no pollution to water and surrounding environment, and has good self tightness and rust resistance.
In the construction, it has the advantages of reliable quality, lower cost, shorter construction time and convenient use. Fundamentally change the force of the equipment base, so that it can evenly bear all the load of the equipment, so as to meet the installation requirements of all kinds of machinery and electrical equipment (heavy-duty equipment, high-precision grinder). It is ideal grouting material for the era of no pad installation. Used for equipment foundation secondary grouting; Anchor bolt anchoring and reinforcement embedding; Concrete structure reinforcement and repair.
Product performance :
- early strength, high strength: the 1 days compressive strength more than 25Mpa; the 3 day compressive strength is more than 45Mpa; the 28 day compressive strength is more than 65Mpa;
- micro expansion: ensure the close contact between the equipment and the base, and no shrinkage after two grouting.
- high self flow: it can fill all gaps and meet the requirements of the second grouting.
- anti segregation’anti cracking’ strong
- products conform to JG/T986 -2005, A.S.T.M A80-1990
Instruction :
The first step: basic treatment. The foundation that should be rough, clean surface, can not have gravel, mud, dust, dirt and other debris release agent;
The second step: set up model. The template is set up according to the grouting construction drawing. The seams between the template and the base, the mold plate and the template are sewed with cement paste, tape and so on. The horizontal distance of the template and the base of the equipment should be controlled around 100mm. The top elevation of the template should be higher than the 50mm on the surface of the equipment base.
The third step: mix the grouting material. Generally, it is stirred according to the standard of 14-15%, and the type of peststone is stirred according to the standard of 9-10%. It is recommended to use mechanical agitation, and the mixing time is generally 1-2 minutes (strictly forbidden by hand drill). When artificial mixing is used, the water consumption of 2/3 should be added first for 2 minutes, and then the remaining amount of water is added to be stirred evenly. Ensure that the material will be used up within 40 minutes. It is forbidden to add any admixture and external admixture in the G02 grouting material when used in the field.
The fourth step: the construction method of the grouting material. Subsection construction should be adopted for long equipment or light rail basis. When grouting is done for two times, grouting should be carried out from one side or on the other side for many times until the other side spills, so as to facilitate exhaust during grouting and not to pour from four sides simultaneously. When the thickness of the grouting is more than 150mm, the high strength non shrinkage grouting material of the bean stone reinforcement should be adopted.
The fifth step: maintenance. After 30 minutes of filling, wet grass cover or rock wool should be covered and kept moist. At 3-6 hours after filling out cut along the edge of equipment to 45 degree angle, to prevent free end cracks, such as unable to handle trimming, should be after 3-6 with a spatula in grouting pressure grouting layer surface pressure light.
Packing, storage and transportation :
- The product is packed in woven bags of 25 kg or 40 kg per bag
- The warranty period of the product is 12 months. Should be stored in a cool and dry.
