(A) the advantages and disadvantages of blue bricks

1, what is a blue brick?

The blue brick is made of clay, which is cooled by adding water during the firing process, so that the iron in the clay is blue without complete oxidation. The fired blue brick is what we call blue brick.

2, the advantages of blue brick:

(1) Blue bricks are extremely breathable and absorbent. Houses built with blue bricks can maintain air humidity, wear resistance and will not rot for ten thousand years.

(2) The blue brick is refined from natural clay, and the product after firing is bluish black, which has the characteristics of strong compactness, good frost resistance, no deformation and no discoloration;

(3) Black, white, gray and blue bricks are made of oxygen-free natural raw soil, which is warm in winter and cool in summer at home, healthy and environmentally friendly;

(4) Trace sulfur contained in blue bricks can sterilize, balance chemical gases harmful to human body such as formaldehyde in decoration, and keep indoor air humidity;

(5) The plasticity of the blue brick is very strong, and the blue brick building has a classical charm, giving people an elegant, calm, simple and quiet aesthetic feeling.

3. Disadvantages of blue bricks:

(1) is more expensive. The price of blue bricks is more expensive than that of red bricks.

(2) Improper collocation and selection of blue brick houses will be neither fish nor fowl.

(3) The indoor light in a blue brick house will be dim.

(B) the advantages and disadvantages of red brick

1, what is a red brick?

Red bricks are also fired with clay, which contains iron. When completely oxidized during firing, iron oxide is red, which is our common red brick.

2, the advantages of red brick:

(1) Red bricks are durable. Red bricks are easy to absorb water and have certain strength and durability. The porous characteristics of red brick will make it have a certain thermal insulation and sound insulation effect, and brick wall and cement mortar can be well combined.

(2) Red bricks have respiratory characteristics and can adjust indoor and outdoor humidity.

(3) Fire prevention. The red brick itself is hard, corrosion-resistant and fireproof.

(4) cheap. Low price, convenient transportation and construction.

3. Disadvantages of red brick:

(1) Red brick has high hardness and lacks toughness and elasticity. In the dead weight of a red brick house, once an earthquake happens, the wall will collapse and the brick wall will become a sharp weapon to hurt people.

(2) Red bricks are not environmentally friendly. Red bricks cannot be recycled, resulting in construction waste.
