Abstract

The invention discloses a fabricated building sleeve connecting grouting material based on phosphorus and magnesium materials and a construction method of the grouting material. The grouting materialis prepared from the following raw materials in parts by weight: 80-120 parts of magnesium phosphate cement, 3-16 parts of an additive, 10-25 parts of an admixture and 0-130 parts of aggregates. The phosphorus-magnesium grouting material has good corrosion resistance and freeze thawing resistance, good durability and fluidity, low contractibility, good steel adhesion, strong self-compaction property and environment temperature adaptability, is easy for pouring and can be used for construction at any time; an oxide film can be formed on the surface of the grouting material, has very good associativity and high bonding strength and has good attachment property with sleeves and steel bars; the grouting material can be mixed on site and convenient to construct, the construction procedure is simplified, the grouting material can be condensed and hardened after 10-30 minutes of the grouting, the compressive strength of the phosphorus-magnesium grouting material can reach over 40MPa after 1.5hours of the grouting, and the phosphorus-magnesium grouting material basically does not need to be maintained, so that the construction efficiency is improved, the construction period is greatly shortened, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building structures, and in particular relates to a prefabricated building sleeve connection grouting material based on phosphorus and magnesium materials and a construction method. Background technique [0002] With the continuous acceleration of the urbanization process in our country, in order to realize the sustainable and healthy development of urban and rural construction, it is proposed to change the mode of urban and rural construction, promote the transformation and upgrading of the construction industry, and vigorously promote "construction industrialization" as one of the top tasks. Moreover, urban land is becoming more and more tense, and construction sites are often very narrow, especially as people's awareness of environmental protection gradually increases, prefabricated buildings have gradually developed. [0003] Sleeve grouting connection is a steel bar connection method th...
