Hanoi (VNA) – The production and sale of construction materials from the beginning of this year are quite favourable with stable prices, the Construction Materials Department under the Ministry of Construction evaluated.

Non-baked building materials have been used more than previous years. Currently, 5.5 billion unbaked bricks are produced, making up 24 percent of the total construction materials, meeting the 2015 target of 20-25 percent.

To increase the usage of non-baked materials in construction projects, the Government issued Decision 567 approving the development of non-baked building materials towards 2020.

From March to present, businesses have maintained normal production of construction materials.

Non-baked brick is made from industrial waste such as ash and cinder from thermal power stations and metallurgy factories, stone quarry fine waste and red mud from bauxite factories. Statistics show that from 2015 to 2020, 50-60 million tonnes of waste matter is discharged, which can cause serious harm to the environment. However, with this amount of waste matter, 40 billion bricks could be produced.

In addition, non-baked building materials are much slighter than other kinds of materials that can help reduce base expenditure. Therefore, they are very suitable for construction works in weak land areas.-VNA
