The main objective is to produce lightweight concrete with adequate strength. The study here applied foaming agent to produce concrete that are lightweight.
This research is part of an on-going effort to produce strong foundation on soft soils using concrete as the base. The main objective is to produce lightweight concrete with adequate strength. The study here applied foaming agent to produce concrete that are lightweight.
The basis of this ongoing study is to obtain a mix-proportion that would produce concrete that are lightweight yet strong for use as road base. Several mixing attempts have been made to produce normal and high performance concrete, respectively.
Among problems faced is foam instability after casting, mixes segregation, concrete brittleness, determination of foam optimal amount, and the achievement of a lightweight density. At present investigation, adding foam to self-compacting (SC) mixes showed a more positive outcome that other mixes; the hardened concrete is strong stable and light.
The study now narrows down to the SC mixes as a base for determining the optimum amount of mix proportion for foamed concrete to be used as road base on soft soil. In addition, further investigations are needed on the design aspect of the foundation, floatability, optimum strength and density, as well as use of fly ash and recycled plastics.

Styrofoam or copper - both materials have very different properties with regard to their ability to conduct heat. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the University of Bayreuth have now jointly developed and characterized a novel, extremely thin and transparent material that has different thermal conduction properties depending on the direction. While it can conduct heat extremely well in one direction, it shows good thermal insulation in the other direction.
Thermal insulation and thermal conduction play a crucial role in our everyday lives - from computer processors, where it is important to dissipate heat as...
In order to advance the transfer of research developments from the field of quantum sensor technology into industrial applications, an application laboratory is being established at Fraunhofer IAF. This will enable interested companies and especially regional SMEs and start-ups to evaluate the innovation potential of quantum sensors for their specific requirements. Both the state of Baden-Württemberg and the Fraunhofer-Gesellschaft are supporting the four-year project with one million euros each.
The application laboratory is being set up as part of the Fraunhofer lighthouse project »QMag«, short for quantum magnetometry. In this project, researchers...

Researchers from the University Hospital Zurich, ETH Zurich, Wyss Zurich and the University of Zurich have developed a machine that repairs injured human livers and keep them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation saving many lives of patients with severe liver diseases or cancer.
Until now, livers could be stored safely outside the body for only a few hours. With the novel perfusion technology, livers - and even injured livers - can now...
A balloon-borne scientific instrument designed to study the origin of cosmic rays is taking its second turn high above the continent of Antarctica three and a half weeks after its launch.
SuperTIGER (Super Trans-Iron Galactic Element Recorder) is designed to measure the rare, heavy elements in cosmic rays that hold clues about their origins...
