Good afternoon, friends! It's time for community interaction again
This week's DOP Community Q&A is covered by questions from @缇欧娜 Community:
△ DOP Community Issues
What is the difference between fair-faced concrete and concrete?
What is decorative concrete?
△ Koshinoi (Tadao Ando/1981)
In recent years, cement decorative walls have been highly sought after
It can be seen everywhere in architecture and indoors
Concrete is not just a cold gray tone
Like fair-faced concrete, translucent concrete, permeable concrete, colored concrete, imitation fair-faced hanging board and coating......
So what's the difference between these concretes?

Thanks @崔孟春
1. What is the difference between concrete and fair-faced concrete?
Let's first take a look at the difference between fair-faced concrete and traditional concrete:
Similarity: There is no difference in raw materials;
Different:
a. Different material ratios: the surface of the traditional poured concrete is rough and needs to be decorated twice; However, fair-faced concrete belongs to one-time pouring molding, and only one or two layers of transparent protective agent are coated on the surface;
b. Different decorative effects: the surface of fair-faced concrete is smooth, the color is uniform, natural and simple, with a unique sense of art, and the corresponding construction technology requirements are relatively strict;
c. The process formwork is different: the utilization rate of fair-faced concrete formwork is low, about 5-6 times, and the utilization of special modeling is lower; Traditional concrete formwork with three construction sites is no problem;
d. Construction technology of fair-faced concrete
2. Translucent concrete
a. Transparent concrete is composed of a large number of optical fibers and delicate concrete;
b. The fibers between the two planes of concrete are placed in parallel in the form of a matrix, showing the visual effect of "holding the pipa and half covering the surface" according to different design requirements.
c. Construction and installation of translucent concrete
3. Colored concrete
a. Colored concrete is actually to inject pigments into concrete, nothing special, but because most of them are mixed and poured by hand, color difference is an inevitable problem.
b. Colored concrete construction technology
Formwork installation - concrete pouring - powder and flattening - compression molding - moisturizing and curing - joint filling - cover protection
Compression molds
Compression moulded colored concrete pavement construction
Paper mould colored concrete is exactly the same as stamping mould practice, and the paper mould is laid on top of the concrete before it is painted.
Common lines on paper molds
Permeable concrete, imitation water hanging board......
Have you used these two types of concrete in your design?
In addition to the concrete listed above, what other materials do you know that have a similar effect to concrete?
