Hai Phong(VNA) – Vietnam lacks control over non-fired brick quality despite the largenumber of such bricks produced in the country over the last five year, theMinistry of Construction said.
Most of the non-firedbrick manufacturing enterprises evaluate their product quality by themselvesbased on Chinese and Korean standards, according to Do Tien Thinh, an expertfrom the Vietnam Institute for Building Science and Technology under theconstruction ministry.
Vietnam had notdeveloped national standards for the processes of designing, producing,inspecting and testing of non-fired bricks, he said at a conference onevaluating the first phase of a national project on increasing the productionand use of non-fired bricks in Hai Phong City last week.
His remarks weresupported by a representative from the Vietnam Concrete Association, whostressed the importance of having uniform quality standards to stabilise thenon-fired bricks’ price.
According to Nguyen XuanBinh, Vice Chairman of the city’s People’s Committee, the traditional redbricks remain a consumer favourite.
Even though the unitprice of non-fired bricks is higher than of red bricks, the total cost of aconstruction built with non-fired bricks, from the design to the constructionphase, is lower than the one built with traditional bricks, he said.
Approved by the PrimeMinister in 2010, the project is aimed at increasing the percentage ofnon-fired bricks to 40 percent of the total number of bricks produced in thecountry by 2020, as well as reducing the amount of greenhouse gasemission.
Some 250 non-fired brickproduction lines must be developed nationwide in order to reach the objective,said Deputy Construction Minister Tran Viet Thanh.
Five billion non-firedbricks were produced in the country last year, accounting for 24 percent of theyear’s total quantity of building materials, according to reports from theconstruction ministry.
The number helped save8.5 million sq.m of clay, some 825,000 tonnes of charcoal and reduced 3.1 tonnesof CO2 emission, according to the reports.
The project hasdeveloped training programs on non-fired technologies and provided training for350 brick manufacturers from 24 provinces and cities across the country thisyear.

The Prime Minister has approved the project “Promotion of non-fired brick (NFB) production and utilisation in Vietnam”, funded by the Global Environment Facility (GEF).
The Government is urging construction companies to use unbaked bricks in place of traditional bricks, the production of which cuts into agricultural land and pollutes the environment.
The production and sale of construction materials from the beginning of this year are quite favourable with stable prices, the Construction Materials Department evaluated.
Results and experience from a project on increasing the production and use of non-fired bricks were introduced at a workshop held in the northern province of Thai Nguyen on June 10.
A boom in the production of clay bricks has worsened air quality in the Mekong Delta and the overexploitation of clay has severely affected arable land.
The programmes have brought about positive changes to rural infrastructure, comprehensively improved the material and spiritual lives of farmers, and contributed to Vietnam's economic restructuring, said PM Pham Minh Chinh.
The festival highlighted the contributions and robust development of Vietnam's revolutionary press over the past century while promoting press products and showcasing the creativity of Vietnamese journalists.
The programme on sustainable poverty reduction has achieved its annual targets for reducing the poverty rate as assigned by the National Assembly and the Government. It has fulfilled five specific objectives and five five-year goals, and met nine out of 12 indicators related to addressing basic social service shortages.
UNICEF stands ready to support the Government in implementing this important law and in continuing to invest in teachers as the cornerstone of a resilient, inclusive, and high-quality education system for all children.
PM Pham Minh Chinh highlighted how Vietnam's revolutionary press has continuously evolved and strengthened over the past century, affirming its role as a sharp and vital political, cultural, and ideological weapon serving the Fatherland and the people in the glorious revolutionary cause of the Party.
Vietnamese Consul General in Fukuoka Vu Chi Mai highlighted the growing demand for Vietnamese workers in Kyushu, especially in Fukuoka, Oita, and Saga prefectures. Currently, the region employs about 35,000 Vietnamese manual workers and over 5,000 IT engineers.
In Vietnam’s case, she said, President Ho Chi Minh demonstrated his strategic vision by founding the revolutionary press a century ago. The late leader understood the press's role not only as a means to reflect the country’s realities but also as a powerful tool to strengthen national unity and inspire the resistance wars and national construction process.
In recent interviews granted to the Vietnam News Agency (VNA)'s reporters in Mexico, prominent figures reflected on the press’s legacy and its global influence.
VietnamPlus e-newspaper of the VNA clinched an A prize in the “Outstanding Press Product” category for its immersive 3D multimedia project, “Epic of Reunification,” a groundbreaking blend of storytelling and technology. The VNA won another A prize for its eye-catching exhibition booth.
Today, the press for foreign service has evolved into a distinct, irreplaceable force, bridging Vietnam with the world and portraying a nation that is stable, peace-loving, and fully integrated into the international community.
At a review conference held on June 21, Deputy Minister of Construction Nguyen Van Sinh praised the province’s scientific, coordinated, and flexible approach. He noted that the early completion reflects the strong commitment of local authorities, the business community, philanthropists, and residents in improving housing conditions for disadvantaged groups.
The VNA delegation, led by General Director Vu Viet Trang, actively participated in the event, engaging in both professional and diplomatic activities.
In the context where AI dominates and produces vast volumes of content, the only sustainable path forward for journalism is to focus on high-quality content and core values. Journalism must redefine its mission - not to report the fastest, but to provide the most profound and trustworthy value.
Granma and the VNA have great potential for cooperation, especially in sharing content regularly, so that VNA products are published on Granma platforms and vice versa, thereby helping Cuban and Vietnamese people access true information and gain a deep understanding of each other's country and people.
During his stay in China’s Guangzhou city from 1924 to 1927 to prepare for the establishment of a Communist Party to lead Vietnam’s revolution, President Ho Chi Minh founded “Thanh nien” newspaper and released its first issue on June 21, 1925.
Vietnam and Cambodia are hoped to strengthen their robust collaboration across various sectors, particularly in resolving remaining border issues to transform the border area into a zone of peace, friendship, cooperation, and development.
The strategic product, managed and operated by the Vietnam News Agency Digital Media Centre (VNA Media), is an official channel for popularising the Party and State’s information and documents as well as delivering mainstream and trustworthy news to both domestic and international audiences through various kinds of multimedia formats.
Since President Ho Chi Minh founded Thanh Nien (Young People) newspaper in 1925, the Vietnamese revolutionary press has become the voice of the people. During the resistance war against the colonialists, journalists took great personal risks to inspire patriotism and the will of rising up against foreign invaders.
The total investment exceeded 319 billion VND (12.2 million USD), including over 261 billion VND from the state budget and 57.5 billion VND mobilised from businesses, organisations, and individuals.
