Concrete is a "high-level" expression on concrete materials. It can see a core artistic beauty and reflect the taste of "no powder. Cold water concrete has a simple and unadorned, of course, stable appearance and charm. It is inherently thick and elegant that some modern buildings cannot learn from and beautiful. The soft feeling, hard feeling, warm feeling and cold feeling of raw materials not only affect people's perception and spiritual essence, but also convey the emotion of engineering construction. Therefore, architectural designers feel that this is a kind of noble, elegant and simple, looks simple, but in fact, it has more expressive effect than the brilliance of the golden wall.

The water concrete structure refers to the one-time pouring and forming, the surface of the concrete does not make any architectural decoration, and the natural layering of the concrete is immediately selected as the actual effect of the veneer, highlighting the natural color layering of the concrete, and according to the pattern patterns such as standard lines on the surface of the concrete, a structure of decorative modeling and design concept is achieved. The concrete structure stipulates accurate appearance specifications, neat and smooth concrete surface, uniform color distribution, no trauma damage and damage problems, settlement joints set neat and elegant, can not occur common engineering quality problems such as honeycomb, surface, emery cloth, etc., so that the concrete main project has a natural beautiful appearance.

In the application of concrete, the concrete surface skills that were not modified before, the use of modern exterior wall repair technology, the cement wall after the removal of the template to be processed, so that the concrete surface to achieve a very exquisite level, but also fully demonstrate the concrete itself Unique original and unadorned side.

There are many kinds of concrete admixtures with various functions, including high-performance water reducing agent Han Li culture education and training fees (early strength type, basic type, initial setting type), high-efficiency water reducing agent (basic type, initial setting type), general water reducing agent (early strength type, basic type, initial setting type), air-entraining water reducing agent, pumping agent, retarder, air-entraining agent, antifreeze, expansion agent, waterproof coating and accelerator, etc.

Main functions of concrete admixture:

1, improve the fluidity of concrete concrete mixture admixture;

2, adjust the concrete solidification time, hard bottom Han Li culture education training fee performance admixture;

3, improve the durability of concrete admixture;

4, improve the performance of concrete admixture;

5. Improve the adhesion between stone and cement mortar page, and improve the holding force between building steel bar and concrete.

concrete admixture use specification:

1, admixture varieties should be selected according to the construction engineering design and construction standards

2. It is forbidden to apply the admixture that causes harm to human health and causes environmental pollution to the surrounding environment.

3, the construction of reinforced concrete and durability standards of the sea concrete, need to pay attention to the total number of chloride ions and alkali
