First concrete and non-metal reinforcement houses built in Vietnam

The first ten out of forty projected houses built with the new technology of concrete and non-metal reinforcement will be given to families who have difficulties in accommodation in the two Southern provinces of Ca Mau and Ben Tre in the middle of this May.

According to construction professionals, the structure of concrete and non-steel reinforcement made from glass fiber reinforced polymer (GFRP), polypropylene fiber (PP), or polyethylene fiber (PE) is considered an innovative solution for constructions built on the sea or in harsh environments, gravely affected by wind, corrosion, and saline water.

As informed by Mr. Tran Quang Hoai, General Director of the Directorate for Natural Disaster Prevention and Control under the Ministry of Agriculture and Rural Development, since 2017, his office has launched a social campaign to support accommodation for poor families who are living in areas with harsh environments or grimly affected by climate change (higher sea level, land slide, saltwater intrusion).

The Southern provinces of Ca Mau and Ben Tre are the first two locations to implement this campaign when Ba Ria Vung Tau Urban Sewerage and Development One Member Limited Company (BUSADCO) carried out the task of building houses with the new technology of concrete and non-steel reinforcement. The construction plan is financially supported by Tan Dai Hung Plastic Joint Stock Co. (with the amount of VND2billion, or $87,846). These houses are supposed to be soundproof, heatproof, and waterproof.

Mr. Hoang Duc Thao, General Director of BUSADCO, said that in this new structure, the foundation, column, beam, girder, and walls are fabricated with non-steel reinforcement concrete. These have suitable joints or slots, edges so that they can be assembled smoothly and firmly. All the walls are completely waterproof, which are examined by the experimental method of long-term monitoring on water pumping with two covered ends.

Thanks to being fabricated in a factory, the construction of the parts is not affected by weather condition, reducing the working time to one third of the conventional construction method. As a result, the building cost is also decreased by 30 percent.

The technology of concrete and non-steel reinforcement has been successfully applied by BUSADCO into many projects to build the infrastructure for various areas nationwide.

This solution is part of the group construction project ‘Building synchronous infrastructure in urban and rural areas while protecting the environment, preventing natural disasters, and coping with climate change’. The solution has received the Ho Chi Minh Award on Science and Technology.

This solution has been implemented in the project of building the embankment and raising the growing bed for mangrove trees in Thai Binh Province, the project of upgrading and building dykes in Can Gio District of Ho Chi Minh City, the project of building technical trenches for cables in Ba Ria Vung Tau Province.

“Non-steel reinforcement concrete has the prominent advantage of light weight compared to traditional materials. It can also prevent corrosion and erosion. Therefore, it could be an ideal solution for constructions in areas which are now gravely affected by climate change in Vietnam”, said Mr. Hoang Duc Thao.
