Vietnamese students' 'cement-free concrete' project featured at Dubai exhibition

(Dan Tri) - The cement-free concrete production project of a group of students from the University of Mining and Geology was selected as one of 100 projects displayed at an exhibition in Dubai (UAE).

From November 27 to December 2, students from more than 100 countries around the world introduced innovative projects to solve practical problems in the fields of natural sciences, humanities, technology and technological innovation research at the "The Prototypes for Humanity" exhibition in Dubai (UAE). The "Green concrete" project of a group of Vietnamese students surpassed more than 3,000 competitors to be selected as one of the 100 most effective and beneficial projects for the community, displayed at the above exhibition. The project of the Vietnamese student group was displayed along with projects originating from the world's most prestigious academic institutions including MIT, Harvard, Cambridge...

A group of 5 students from the Vietnam University of Mining and Geology, including Nguyen Trung Hieu, Vo Dinh Trong, Nguyen Xuan Cong, Bui Duc Tung, and Dang Quanh Minh, guided by Dr. Tang Van Lam, was selected to display their project at this exhibition. The "Green concrete" project aims to manufacture a product that is a "green" concrete mixture completely without cement, pre-mixed, packaged in bags weighing 25 kg/bag. The compressive strength of this "green" concrete product has reached over 60MPa, and has attracted the attention and orders of many businesses . According to Dr. Tang Van Lam, who guided the group of students implementing the project, the most different point of the project compared to previous studies is that the "green" concrete without cement uses 1% aluminum oxide powder - Al2O3 combined with thermal power fly ash, finely ground blast furnace slag, and strong alkaline solution. The above combination aims to create more gels with adhesive properties, linking aggregate particles together to form a solid, high-strength concrete block, removing excess alkali in the concrete, reducing the phenomenon of moss and mold "growing hair" on the surface of the product after shaping and increasing the efficiency of using this product in construction works.

Within the framework of the COP28 Global Climate Change Summit in Dubai, the group of students implementing the "Green concrete" project met with Prime Minister Pham Minh Chinh. At the meeting, the Prime Minister was very pleased to know that Vietnamese students have made important progress, affirming the value of science and technology with friends around the world. The Prime Minister also praised and congratulated the group of students for their encouraging achievements, contributing to demonstrating the highly effective quality of education in our country.
