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.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
