Problems solved by technology

[0004] At present, the wall materials in the construction industry mainly use solid blocks or hollow blocks. Ordinary solid blocks or hollow blocks are not easy to build, and the accuracy of building adjacent bricks in the left and right directions cannot be guaranteed; Blocks on the same floor are of the same height, especially at the end of the wall
In addition, the integrity of the wall made of ordinary hollow blocks is poor, and the anti-side and anti-crack properties are not ideal. Its fatal shortcoming is the poor anti-seismic performance.

Abstract

The invention discloses a high-performance fiber-reinforced cement composite concrete building structure block. The high-performance fiber-reinforced cement composite concrete building structure block is prepared from the following components: fly ash, cement, attapulgite, sand, waste paper pulp, natural gypsum, manganous slag, polycarboxylic acid, sodium methylsiliconate, colloidal silicon dioxide, fatty acid polyoxyethylene ester, calcium nitrate, naphthalene sulfonic acid sodium salt-formaldehyde condensate, modified lignosulfonate, diboron trioxide and a nano activator. A groove parallel to a block edge is formed in at least any one surface of six surfaces of the block; channels are formed between every two adjacent left and right blocks as well as between every two adjacent upper and low blocks; all the channels are filled with mortar. The block disclosed by the invention has the advantages of impact resistance, high strength, simple structure and convenience in building; the building precision and the stability of a wall body are guaranteed; the lateral force resistance, crack resistance and seismic performance are greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a high-performance fiber-reinforced cement composite concrete building structure block. Background technique [0002] Blocks are artificial blocks used for masonry, and are a new type of wall material. Most of them are rectangular hexahedrons, and there are also various special-shaped blocks. Blocks are artificial blocks made of concrete, industrial waste (slag, fly ash, etc.) demands for institutional reform. Blocks can be divided into solid blocks and hollow blocks according to their appearance and shape. Blocks with a hollow rate less than 25% or without holes are solid blocks; blocks with a hollow rate greater than or equal to 25% are hollow blocks. Hollow blocks have three forms: single row of square holes, single row of round holes and multiple rows of flat holes, among which multiple rows of flat holes are more beneficial to heat preservation. According to ...
