In the industry of building materials: building materials produced according to traditional methods spend the energy, raw materials, low economic efficiency, caused heavy environmental pollution, should be handled in the process of industrialization. One of the goals of striving to 2020 of the construction materials industry is building an eco-friendly industry environment, towards a green industry. The orientation of the "master plan for Vietnam building materials development to 2020" mentioned the issue of focus on developing new materials, friendly to the environment.1 unbaked Bricks.One type of building materials environmental impact is the terracotta tiles. Many countries in the world have reduced the use of brick, clay, brick clay moved at the rate of 50-70%. According to statistics by the DR. Tran Van Huynh, Chairman of the Vietnam construction materials provide the production of clay bricks in our country every year to exploit large clay 1, 5 m 3/1,000 bricks. As such, the production of terracotta tile consume large amounts of agricultural land. Furthermore, a brickmaking kilns craft polluting the environment severely. The technology of extraction and processing of raw materials for the production of traditional building materials production mainly small, backward technology, do eat the fragmented, leading to poor quality, waste resources, seriously undermining the ecological environment.The 2010 estimate, producing 24 billion bricks cost 36 million m3 of clay, the equivalent of 1,800 ha of arable land. In the 10 years from 2011-2020, to produce 374 billion bricks to 560 million m3 of clay extraction, equivalent to 28,000 hectares of arable land and spend about 60 million tons of coal. Therefore, promoting the use of environmentally friendly building materials with the environment becomes an inevitable trend in the industry of building materials.• Ceramic brick or unbaked block is a type of brick that follows the raw shape then manually close the snake reaches the mechanical index such as compressive strength, bending, water absorption ... without the over temperature, not use heat for heating the red bricks to increase the durability of bricks. The durability of unbaked bricks is on the rise thanks to pressure or vibrating or both pressed and shake up the brick and adhesive composition of them.
