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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
