Problems solved by technology

[0003] Traditional grouting materials for prefabricated buildings generally contain sulphoaluminate cement in cement ingredients, and sulfate ions are easy to corrode steel. Secondly, traditional grouting materials for prefabricated buildings generally do not have thermal insulation and cold resistance properties, and secondly, their water retention and plasticity and cohesion are poor, resulting in poor construction performance

Abstract

The invention discloses a preparation method of a special grouting material for prefabricated buildings. The grouting material special for the prefabricated building is prepared from the following rawmaterials in parts by weight: 50 to 80 parts of mud, 1 to 3 parts of cellulose, 80 to 120 parts of sand, 0.01 to 0.05 part of air entraining agent, 0.05 to 0.08 part of a polycarboxylic acid high-performance water reducing agent and 50 to 70 parts of sepiolite. The assembling method is simple and reasonable, the preparation process is simple, safe and reliable, when the prepared potting materialdry powder is used, water is added and uniform stirring and mixing are carried out for use so that during transport, the grouting material dry powder can be used for transportation, compared with a high-fluidity grouting material, the grouting material is more convenient to transport, the sepiolite is added, the sepiolite does not harm the human body and pollute the environment and is a cancerogen-free good heat preservation and heat prevention material, and therefore the cold resistance and heat preservation performance of a building made of the grouting material special for the prefabricatedbuilding are improved, and the service life of the building is prolonged.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a method for preparing special grouting materials for prefabricated buildings. Background technique [0002] With the development of modern industrial technology, building houses can be manufactured in batches and in sets like machine production. As long as the prefabricated building components are transported to the construction site and assembled, the prefabricated building began to arouse people's interest in the early 20th century, and finally realized it in the sixties. Britain, France, the Soviet Union and other countries first made attempts. Due to the fast construction speed and low production cost of prefabricated buildings, they were quickly spread all over the world. The early prefabricated buildings were relatively rigid in shape and uniform in appearance. People improved in design later, added flexibility and diversity, made assembled architecture t...
