Problems solved by technology

[0002] In hydraulic concrete engineering, concrete engineering such as spillway, spillway, diversion tunnel, scour gate, highway pavement, airport runway, parking apron, machine tool, large-scale equipment foundation, industrial plant, etc., has a service life of 4 / 4 that of ordinary concrete One to one-sixth, the main reason is that in the material composition of ordinary concrete, cement stone has poor density and low cohesion. When subjected to external force grinding, the weak link of concrete will be washed away first, and then the overall concrete will be destroyed. , the service life of concrete is significantly shortened. In order to ensure the normal operation of the project, a lot of maintenance costs need to be invested, and at the same time affect the normal progress of the project, causing extremely serious losses

Embodiment 1

[0025] To prepare concrete anti-impact and wear-resistant agent (solid product), it is required that the concrete has excellent compactness, high flexural compressive strength, good fatigue resistance and wear resistance. The proportion of the anti-impact and anti-wear agent is (calculated by weight ratio): Sulfamate 40%, Aluminum Sulfate 25%, Triethanolamine 2.0%, Ferric Chloride 1.5%, Silicon Oxide Powder 3 1.5%.

Embodiment 2

[0027] Prepare concrete anti-shock and anti-wear agent liquid product, its proportioning (by weight): polycarboxylate 8.0%, triethanolamine 5%, iron trichloride 5%, water 10%.

Embodiment 3

[0029] The preparation of pumped concrete wear-resistant agent powder products should not only have the requirements of impact and wear resistance, but also have a pumping function, and will not block the pipeline when the sand rate and cementitious material are low. The ratio is (according to Calculated by weight percentage): sulfamate 30%, naphthalene sulfonate 15%, silicon oxide 2 1.5%, ferrous chloride 1%, triethanolamine 2.0%, air-entraining agent 0.5% (powder), retarding Agent 3.0% (powder), calcium sulfoaluminate 25%, cellulose (hydroxyethyl) 2.0%.

Abstract

The present invention provides one kind of antishock and antiwear composition for concrete and its preparation process. The antishock and antiwear composition for concrete consists of plasticizing agent in 35-80 wt%, triethanolamine in 2.0-6.0 wt% and chloride in 1.0-6.0 wt%. The antishock and antiwear composition for concrete in powder or liquid form has high density, slight expansion, water reducing performance, plasticizing performance, capacity of strengthening concrete, etc, and is used in raising the antishock and antiwear performance of concrete and increasing its service life.

Description

technical field [0001] The invention relates to a composition, in particular to an anti-impact and anti-wear agent composition used in concrete (mortar) engineering and a preparation method thereof. Background technique [0002] In hydraulic concrete engineering, concrete engineering such as spillway, spillway, diversion tunnel, scour gate, highway pavement, airport runway, parking apron, machine tool, large-scale equipment foundation, industrial plant, etc., has a service life of 4 / 4 that of ordinary concrete One to one-sixth, the main reason is that in the material composition of ordinary concrete, cement stone has poor density and low cohesion. When subjected to external force grinding, the weak link of concrete will be washed away first, and then the overall concrete will be destroyed. , The service life of concrete is significantly shortened. In order to ensure the normal operation of the project, a large amount of maintenance costs need to be invested, and at the same ...
