Problems solved by technology

They not only caused serious corrosion damage to the eyes and skin of construction workers, but also caused the loss of 20-40% of the later strength of concrete, which seriously affected the support quality of underground engineering; It can improve the early strength, but they have no water-reducing function, and often increase the water demand for construction, which will inevitably increase the water-cement ratio, which will adversely affect the strength of concrete

Abstract

The invention discloses an accelerating agent with low adding amount, and a preparation process thereof, wherein the accelerating agent is prepared mainly from zinc sulfate, hydrogen peroxide, polymeric aluminum sulfate, titanium residue, vanadium residue, soda ash and dextrin. According to the present invention, the prepared accelerating agent has a water reducing function so as to reduce the water consumption for construction, such that the strength of concrete is good.

Description

technical field [0001] The invention relates to a quick-setting agent and a manufacturing process thereof, in particular to a low-dosage quick-setting agent and a manufacturing process thereof. Background technique [0002] In the construction of shotcrete for underground projects and some surface concrete projects, accelerators are often used to accelerate the setting of concrete and improve early strength, and reduce rebound and collapse. Thereby shortening the construction period and achieving better technical and economic benefits. [0003] At present, the commonly used accelerators in China include Hongxing 1 type, 711 type and the Ministry of Coal type. The well-known products abroad are: Sigunit and SIKA. These accelerators all use alumina clinker (industrial sodium aluminate) and soda ash as the main raw materials. They not only caused serious corrosion damage to the eyes and skin of construction workers, but also caused the loss of 20-40% of the later strength of...
