Abstract

The invention relates to a concrete accelerator with high anti-seepage grade. The concrete accelerator is prepared from the main components of bauxite, sodium carbonate and quicklime; the main components are mixed and fired into clinker, and the clinker is added with 50 to 80 parts of cellulose, 5 to 15 parts of unshaped silicon dioxide, 15 to 20 parts of sodium fluoride, and 5 to 10 parts of polyethyleneimine; the amount of cellulose is preferably 70 parts. Compared with the prior art, the concrete accelerator has the beneficial effect that by adding the hydroxypropyl methyl cellulose, the unshaped silicon dioxide, the sodium fluoride and the polyethyleneimine, the better effect is realized.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete quick-setting agent with high impermeability level. Background technique [0002] Accelerator, before use, should be used in a trial mix test for the cement used in the project, and the dosage should be selected before it can be used in large quantities. The stored expired cement cannot be used, and the cement that does not meet the national standards cannot be used. Proper storage is required for the accelerator to prevent damp caking and failure. Strengthen the early water spraying maintenance to ensure the later strength. Contents of the invention [0003] The technical problem to be solved is to overcome the defects existing in the prior art and provide a high-impermeability concrete quick-setting agent. [0004] The technical solution adopted in the present invention is a high-impermeability concrete quick-setting agent, the main component of which is clinke...
