Using unburnt bricks is cracked
In Hai Phu commune of Hai Lang district (Quang Tri), at the end of 2016 there were 2 state budget projects, Hai Phu Secondary School and Hai Phu Medical Station, built. Both of the above works use unburnt bricks to build according to regulations. However, during the construction process, cracks appeared and were treated. In 2017, 2 projects were handed over and put into use.
“Even though it has been handled, when it was put into use, Hai Phu Secondary School still had cracks. Technical staff said that in the long run, it will crack more because this brick has some compression. Having learned from experience, the project of Hai Phu Primary School had to ask the investor to switch to baked bricks, and the construction process had no problems “- Mr. Truong Cong Van – Secretary of Hai Phu Commune, informed.
Not only in Hai Phu commune, but also in Hai Lang district, many works using unburnt bricks in the construction process have cracks. Mr. Pham Dinh Loi, Vice Chairman of the District People’s Committee, said that the quality of the unburnt bricks used in the construction of the building is now severely cracked. “There is a project that the contractor can’t hand over when the project is finished, I don’t know if it’s because of the grade of this material, or because the concrete marks built with brick material are passed through the unburnt brick material, or because of the temperature.” – Mr. Loi, asked.
In March 2018, the Department of Construction of Quang Tri province established an inspection team to inspect and supervise a number of projects using unburnt materials in the city.
