Lightweight concrete with controlled pores by 3D printed micro frame

总结

A novel process for producing lightweight concrete structures with increased compressive strength. This novel process can precisely control the size, quantity and distribution of air voids to achieve a higher strength than any other traditional foam concrete.

技术优势

- Increased compressive strength with reduced weight
- Non-brittle and high capacity at large strain/deformation
- Precise control of properties through design process
- Increased energy adsorption during loading

技术应用

There is an increasing industrial need for lightweight concrete materials that can sustain high levels of compressive strength.

详细技术说明

Monash researchers have invented a process for precisely controlling the shape, size and distribution of air voids within concrete structures. The result is increased compressive strength whilst simultaneously reducing weight, giving a foam concrete that meets the need for strength combined with light weight.

To achieve the precise control of the pore properties, three-dimensional micro-frames are covered with specific cement paste mixtures. Surface tension of the cement paste aligns it into sheets in the direction of the micro-frame lattice. This results in highly aligned, thin-walled concrete sections of almost any shape.

Structures have been produced with a compressive strength of up to 7.5MPa whilst simultaneously having a dry density of 445 kg/m3.
