Abstract

The invention relates to a high-strength drilling anchoring agent and is suitable for various building projects requiring higher durability such as large-tonnage anchor rods, anchor cables and tail anchorage of equipment. The high-strength drilling anchoring agent is mainly formed by the mixture of powder mainly consisting of silicate minerals; volcanic ash activated powder, coal ashes or slag or silicon powder, reduced and contracted activated powder, sulphoaluminate minerals; reduced and contracted inert particles, surfactants, naphthalenesulfonic formaldehyde condensation compound, sulfate, amine, retarders, salt calcium or ignosulfonate and water retaining agent and cellulose ethers. The high-strength drilling anchoring agent is characterized by long operation time, no toxicity or harm to human and environment, high early strength, stable development of later strength, strong erosion-resistance and high durability.

Description

technical field [0001] The invention relates to a kind of anchor rod reinforcement suitable for various underground projects, dangerous high slopes, engineering repairs, foundation feet in equipment installation, secondary grouting of equipment foundations, and protection, repair and repair of scoured surfaces of concrete buildings. High-strength drilling anchoring agent for caulking and grouting. technical background [0002] Suitable anchoring or grouting materials are required for underground engineering, rock mass reinforcement and engineering repair of high-risk slopes, as well as equipment installation feet and secondary grouting for equipment foundations, but general cement-based anchoring or grouting materials There are generally disadvantages such as slow curing of materials, low early strength, large shrinkage, long stretching age, and low anchorage strength. Contents of the invention [0003] The purpose of the present invention is to provide an anchoring and g...
