Quantitative production of brick in the country:+ In 2000 was 8.7 billion bricks

+ In 2005 was 16.5 billion bricks

+ In 2010 was 25 billion bricks, adobe brick accounted for 10%,

And expected

+ In 2015 was 32 billion bricks, adobe brick accounted for 20-25%.

+ In 2020 was 45 billion bricks, adobe brick accounted for 30-40%.

Enterprises produce brick with five types of technology:+Tuynel kiln+Hoffman kiln+Bull trench kiln+Traditional kiln+Vertical shaft brick kiln

Fuels: coal, wood, straw, fuel gas, gas, gasification …
