Successfully produce unbaked bricks by polymerization technology
Recently, Phu Tho Consulting and technology development one member limited company has successfully research produce unbaked bricks by polymerization technology “soil petrified” from midland hill soil (poorly or not capable of farming) and raw material in Phu Tho. This is the research project supported by Innovation Partnership program Vietnam – Finland (IPP)

Brick is a very important part of a house or structures. After being shaped, unbaked bricks would self-curing achieve the mechanical indicators: compressive strength, bending, and water absorption… without heat treatment process. Many kind of unbaked bricks are used these days such as: Papanh brick (cement sand bricks) unbaked and was produced from industrial waste as: coal slag, lime which were used in our country long time ago, low intensity mainly used for low load bearing type of wall; Block brick was produced from crushed stone, sand, cement and industrial waste as broken bricks, mortar, concrete… has high strength intensity, can used high building. This type of brick mainly used in areas where the nature puzolan have, spontaneous production, localize and small scale. Specially unbaked bricks from soil material, mixed aggregate and additives has been developed and approached…

Unbaked bricks can be produced from industrial waste, contribute to improve the environment. Unbaked technology minimizes energy consumption, mostly the fossil energy contribute to environmental protection.

According to representative of Phu Tho Consulting and technology development one member limited company: soils petrify unbaked bricks have many advantages compare with normal bricks such as: not emit CO2 and SO2 and other wastes; Clear the environment by using the industrial waste as:  concrete wall, bricks, coal slag, crockery, porcelain; Easy to get input materials; etc.

Besides, the product also solve hundreds of jobs for the local people with sustain income. The manufacture can be set on every terrain also one of many advantages that useful for people. And the price is 10-20% lower than other bricks by using this technology.
