Abstract

The invention discloses a high-efficiency setting accelerator. The high-efficiency setting accelerator is prepared by mixing the following raw materials in parts by weight: 20-30 parts of alum clay, 10-15 parts of sodium aluminate, 2-4 parts of manganese naphthenate, 5-10 parts of 1,4-butynediol, 15-25 parts of HSA (high streace ammonia), 12-18 parts of poly (diallyldimethylammonium chloride), 10-15 parts of polysilicate ferric sulfate, 28-36 parts of SN-II high-efficiency water reducing agent, 2.5-4.5 parts of zinc dialkyl dithiophosphate, 4-6 parts of ethyl cyanoacrylate, 5-10 parts of modified soybean phospholipid, 10-15 parts of quicklime, 7-14 parts of ulexite powder, 5-10 parts of carbomer, 4-8 parts of diglycol dioleate and 3-5 parts of aid. The high-efficiency setting accelerator disclosed by the invention is good in setting acceleration effect and quick in setting, can enable concrete to be initially set within 3min and finally set within 6min and is low in construction water consumption, the water reducing rate of the setting accelerator can reach over 20%, and the setting accelerator can be used for accelerating the setting of the concrete, improving the early strength, reducing resilience and collapse and shortening the construction period, so that the setting accelerator is suitable for underground engineering sprayed concrete and ground concrete.

Description

technical field [0001] The invention relates to a high-efficiency accelerator and belongs to the field of concrete admixtures. Background technique [0002] Concrete admixtures, referred to as admixtures for short, refer to substances that are added to improve the performance of concrete before or during the mixing of concrete. Because admixtures can effectively improve the performance of concrete and have good economic benefits, they have been widely used in many countries, and their application in engineering has attracted more and more attention, becoming an indispensable material in concrete. The quick-setting agent is one of the concrete admixtures, which can make the concrete set and harden rapidly, and form sufficient strength in a short time to meet the requirements of special construction. With the rapid development of the concrete industry, the quick-setting agents currently used in the market have a long setting time and poor quick-setting effect, and cannot achi...
