Abstract

The invention discloses a durable granulated blast furnace slag building block and belongs to the technical field of a building material. The durable granulated blast furnace slag building block is prepared according to the following steps: crushing granulated blast furnace slag and sieving, thereby acquiring refined granulated blast furnace slag; mixing and stirring the acquired refined granulated blast furnace slag and sulfuric acid, soaking and filtering, thereby acquiring the pretreated granulated blast furnace slag; stirring, mixing and fermenting paper-making black liquor, chitosan solution, soybean protein powder and biogas slurry, thereby acquiring a fermentation liquor; mixing the pretreated granulated blast furnace slag and the fermentation liquor, soaking and filtering, therebyacquiring the modified granulated blast furnace slag; mixing and stirring the modified granulated blast furnace slag, gypsum, quicklime, cement, water, modified charring cocoanut fiber and silane coupling agent, thereby acquiring a mixed slurry; injecting the mixed slurry into a mold, pressing and forming, thereby acquiring a blank; placing the blank into a curing chamber and curing, thereby acquiring the durable granulated blast furnace slag building block. The durable granulated blast furnace slag building block provided by the invention has excellent mechanical properties and durability.

Description

technical field [0001] The invention discloses a durable blast furnace slag block, which belongs to the technical field of building materials. Background technique [0002] With the development of the construction industry and the increasing emphasis on the quality of construction projects, the quality and quantity of construction sand, which is one of the basic components of concrete and mortar, has an increasingly obvious impact on the construction industry. On the one hand, the market has higher and higher requirements on the quality of sand, and the quantity is increasing; on the other hand, natural sand resources that meet the quality requirements are becoming less and less, and engineering problems caused by this occur from time to time. With the gradual shortage of natural sand resources and the country's restrictions on the mining of natural sand, as one of the necessary components for concrete preparation, the source of natural sand will be limited, and its market w...
