Early-strength bracket grouting material and preparation method thereof
The invention relates to a grouting material and a preparation method thereof, particularly an early-strength bracket grouting material and a preparation method thereof, belonging to the field of engineering materials. The early-strength bracket grouting material comprises the following components in parts by weight: 390-550 parts of cement, 5-30 parts of fly ash, 350-600 parts of fine aggregate, 20-50 parts of intumescent component, 2-10 parts of water reducing agent, 0.5-10 parts of defoaming agent, 0.5-10 parts of slow setting component, 0.1-2 parts of setting accelerating component and 0.02-1 part of thickener. Therefore, the material has the advantages of favorable workability, long operable time and smooth surface after grouting, can perform natural flow leveling, overcomes the defects of unevenness, high tendency to cracking, peeling and powdering and the like, and is commonly used in the fields of secondary grouting of bridge brackets and large-scale equipment, anchorage of anchor bolts, pavement repair and the like.
