Embodiment 1

[0016] 1) Grind 1kg of tea leaves until the largest particle is less than 0.1mm, put them into 100kg of water for boiling; set the initial temperature to 20°C, and the heating time to 5min; the constant temperature to 95°C, and the constant temperature time to 30min; the end temperature is 20°C, the cooling time is 5 minutes; after repeating 3 times, filter the extract for use;

[0017] 2) Weigh 5 parts of theophylline, 5 parts of tea polyphenols, and 90 parts of activator tea extract by weight;

[0018] 3) Add the mixed material in step 2) to the ultrasonic stirring device at one time, under the ultrasonic condition, stir at a low speed for 60 s, stop stirring for 5 s, and then stir at a high speed for 60 s to obtain the concrete admixture of the present invention.

Embodiment 2

[0020] 1) Grind 1kg of tea leaves until the largest particle is less than 0.1mm, put them into 110kg of water for boiling; set the initial temperature to 20°C, and the heating time to 5min; the constant temperature to 100°C, and the constant temperature time to 30min; the end temperature to 20 ℃, the cooling time is 5min; after repeating 3 times, filter the extract for later use;

[0021] 2) Weigh 5kg of theophylline, 5kg of tea polyphenols, and 90kg of activator tea extract by weight;

[0022] 3) Add the mixed material in step 2) to the ultrasonic stirring device at one time, under the ultrasonic condition, stir at a low speed for 60 s, stop stirring for 5 s, and then stir at a high speed for 60 s to obtain the concrete admixture of the present invention.

Embodiment 3

[0024] 1) Grind 1kg of tea leaves until the largest particle is less than 0.1mm, put them into 120kg of water for boiling; set the initial temperature to 20°C, and the heating time to 5min; the constant temperature to 95°C, and the constant temperature time to 30min; the end temperature to 20 ℃, the cooling time is 5min; after repeating 3 times, filter the extract for later use;

Abstract

The invention provides a concrete admixture and a preparation method. Tea is ground, water is added, the mixture is boiled, and an exciting agent, namely, a tea extracting solution is obtained for later use; theophylline, tea polyphenol and the exciting agent, namely, the tea extracting solution are weighed in a weight ratio, mixed and stirred uniformly; the concrete admixture is obtained throughintermittent mixing under the ultrasonic condition. Effective components of tea are mainly taken as a basis, natural components including theophylline and tea polyphenol in tea are sufficiently utilized for admixture preparation, the tea extracting solution is taken as the excitant, and excitation is performed through multiple amino acids, vitamins, organic acid, lipopolysaccharide, saponin, sterol and the like in the tea extracting solution. The water reducing function and the early strength function of the natural components of the tea on concrete are played, and the concrete admixture has very high social value and ecological value.

Description

technical field [0001] The invention discloses a concrete admixture and also provides a preparation method thereof, relates to an ecological environment-friendly concrete admixture and belongs to the technical field of building materials. technical background [0002] Admixtures are substances added to improve and adjust the performance of concrete. As an important part of the concrete industry, it has played an increasingly important role. Adding an appropriate amount of admixtures to concrete can improve concrete quality, improve concrete performance, reduce concrete water consumption, save cement, reduce costs, and speed up construction progress. It is the least amount of concrete materials but has a great impact on its performance. components. [0003] However, due to the technical requirements of the existing admixtures, it is often necessary to add a large amount of chemical agents in the reproduction process, and the final product can only be obtained after multi-st...
