The cement-based grouting material is a dry-mixed material which is prepared by taking cement as a base material and adding a proper amount of fine aggregate, other admixtures, additives and the like, and has the characteristics of high fluidity, early strength, high strength, no pollution and the like after being mixed with water. The grouting material is widely used for secondary grouting of equipment foundations, grouting of steel structure column foundations, grouting of small-gap bonding of track foundations and the like, anchoring of foundation bolts, reinforcing and repairing grouting of concrete beams, columns, plates and walls, and repairing irregular dead corners, corners and concrete cavities which are difficult to pour of other common concrete.
Along with the development of economy in China, the installation of various ultra-large equipment and the construction of a large number of high-difficulty bridges and railways, higher requirements are put forward on the strength of grouting materials.
The existing cement-based grouting materials have low early strength and poor durability, and affect the stability and durability of equipment installation and building structures, so the improvement and perfection of the performance of the grouting materials are urgently needed
Disclosure of Invention
The invention aims to provide a basalt fiber cement-based grouting material, which is characterized in that basalt fibers are doped into the grouting material, so that the overall strength of the grouting material is improved, and the service life is prolonged.
The technical solution for realizing the purpose of the invention is as follows: the basalt fiber cement-based grouting material comprises the following components in parts by weight: 100 parts of cement, 100 parts of fine aggregate, 120 parts of mineral admixture, 10-20 parts of water reducing agent, 0.2-0.5 part of defoaming agent, 0.2-0.4 part of retarder, 2-4 parts of chopped basalt fiber and 30-35 parts of water.
Further, the length of the chopped basalt fiber is 6-12 mm.
Further, the cement is ordinary portland cement.
Further, the fine aggregate is quartz sand.
Further, the mineral admixture is I-grade fly ash.
Further, the water reducing agent is one of a polycarboxylic acid water reducing agent, a naphthalene-based high-efficiency water reducing agent or a sulfamate high-efficiency water reducing agent.
Further, the defoaming agent is one of emulsified silicone oil, polyoxyethylene, polyoxypropylene or pentaerythritol ether.
Further, the retarder is sodium citrate.
Compared with the prior art, the invention has the remarkable advantages that:
according to the invention, the basalt fibers are doped into the cement-based grouting material in an optimized proportion to fill partial pores of the internal structure of the grouting material, so that the cohesive force among aggregates is enhanced, the dispersion of redundant moisture in the grouting material is promoted, the formation of pores is prevented or reduced, the effect of effectively resisting cracks is achieved, the mechanical property of the cement-based grouting material is improved, and the service life of the cement-based grouting material is prolonged.
