Concrete anchoring agent

Abstract

The invention discloses a concrete anchoring agent. The anchoring agent comprises, by weight, 75-85 parts of cement, 25-35 parts of coarse stone powder, 60-70 parts of fine stone powder, 20-30 parts of fine fly ash, 15-25 parts of clay, 10-20 parts of glass beads, 10-15 parts of sodium lignin sulfonate and 8-12 parts of anhydrous sodium sulfate. The concrete anchoring agent has the advantages that the anchoring agent is high in early strength, is not influenced by temperature and environment, and is high in adaptability with concrete, convenient to construct on site and high in construction efficiency, the fine fly ash is added so that the porosity among various materials can be improved, the compactness of the materials is improved, erosion of harmful ions and freeze-thaw resistance circulation dynamic modulus loss are prevented, durability indexes such as resistance to corrosion of steel bars are greatly improved, the service life is prolonged, the stability and reliability of the solidified concrete anchoring agent are high, and the use safety of the concrete anchoring agent is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of concrete additives, in particular to a concrete anchoring agent. Background technique

[0002] With the rapid development of the economy, the role of concrete in construction has become more and more important, which virtually puts forward higher and higher requirements for concrete. In order to improve the performance of concrete and meet the needs of concrete construction, those skilled in the art often use the method of adding concrete admixtures to concrete. Among them, the commonly used concrete admixtures include anchoring agent, water reducing agent, retarder, early strength agent, waterproofing agent and so on. These types of admixtures have been widely used in practical engineering, and have played an important role in improving concrete properties, increasing construction efficiency and saving investment costs, and have become indispensable materials in concrete.
