Master's thesis of Engineering: Mechanical properties and applications of additively manufactured thermoplastic polyurethane material

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. Additively manufactured TPU mould is developed to cast complex concrete structures. A planar topologically optimized cantilever and a free-form 3D column are cast using the proposed TPU mould. Good surface quality is obtained for the cast concrete elements, and the moulds can be reused many times after cleaning.

Master's thesis of Engineering: Study on effects of flowability on steel fiber distribution patterns and mechanical properties of SFRC

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.

Thesis for the degree of Master of Engineering: Mechanical Properties and Applications of Additively Manufactured Thermoplastic Polyurethane Material

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. The findings of this thesis will provide clear guidelines for the selection of processing parameters for additively manufactured TPU parts and the method of casting complicated concrete structures with additively manufactured TPU mould.

Tổng quan về công nghệ móng cọc và công tác kiểm tra chất lượng thi công - Bộ xây dựng phần 1

Công nghệ thi công cọc nhồi bê tông hay bê tông cốt thép là công nghệ đúc cọc bê tông tại chỗ vào trong nền đất (cast-in-place concrete pile).Phương pháp của công nghệ này là dùng thiết bị tạo lỗ lấy đất lên khỏi lỗ. Đồng thời bơm vào lỗ một loại dung dịch có khả năng tạo màng giữ thành vách hố đào và có trọng lượng riêng hơi nhỉnh hơn nước ngầm trong đất một chút để cân bằng lại áp lực khi lấy đất lên. Tiếp theo làm sạch cặn lắng (bùn lắng và đất đá rời)...
