Synopsis: Civil engineering: Civil engineering generale: Building materials:

The researchers have developed also an alternative to the eave tubes the'eave brick, 'where the plastic with the insecticide-coated netting replaces a brick removed from a wall.

The team calculates a typical household would spend about#1 per person per year over three years for the'eave tubes or bricks'.

'ee close to becoming competitive with bednets, especially when taking into consideration that eave tubes protect everyone in the house and not just those sleeping under a net,

and bricks on up to 7 000 houses one that would yield solid scientific evidence that these tools can be deployed broadly to reduce the burden of malaria.

to make clay soils drain faster and sandy soils drain slower. As more gardeners and farmers add ground charcoal

In the new study biogeochemists at Rice conducted side-by-side tests of the water-holding ability of three soil types#sand clay and topsoil#both with and without added biochar.

When biochar is added to clay it makes the soil less dense and it increases hydraulic conductivity

While growers can use the sensors to monitor water in soils for their crops civil engineers can embed the chips in concrete to determine optimal moisture levels as the concrete cures. ne of our goals is to try

natural ash replaced half the foundation cement (production of which produces five percent of global CO2 EMISSIONS),

An Australian engineer has developed an industrial-sized bricklaying robot that can put down hundreds of bricks per hour, 24 hours a day, with superhuman precision.

Hadrian then cuts its own individual bricks and shuttles them along the articulated arm of a 28-meter-long telescopic boom.

An automated mechanism at the end of the crane arm then places the bricks individually, sealing each with mortar.

By automating the loading, cutting routing and placing and working around-the-clock Picav says Hadrian can complete a standard house structure within two days.

a solid mineral found in eggshells, the shells of various marine organisms, calcium supplements and cement.

This research demonstrates for the first time that it is possible to transmit electric signals in an insulating material.

This new'thirsty'concrete absorbs 4, 000 litres of water in 60 seconds During the first few weeks of August 2007,

a new type of porous concrete that can absorb up to 4, 000 litres of water in the first 60 seconds,

While permeable concrete has been around for the past 50 years, it's mostly been used under pavements to help with drainage,

Not only can the super-absorbent concrete be used in conjuction with existing concrete-cities can install it so the runoff from regular concrete is fed into the Topmix Permeable

-but it will also be significantly cooler than regular concrete during the hottest months of the year."

so the concrete can only be used in places where temperatures are never likely to dip that low,

and other electronic devices eliminating the clunky brick that is commonly comes with a device's power cord.

Prior to use the inhabitants filter the water again with the help of a clay pot that is provided with very small holes.

We re also doing building materials as well--replacing foam insulation. It would mostly be commercial. The question is what s the best way to do it.

with four of these bundles combined together to form a stable and a relatively strong building material,

and insulated with concrete to prevent any leakage from entering local groundwater. Bacteria that naturally occur within cowsdigestive tracts are added to the manure,

Aines says that the MECS-based approach can also be tailored to industrial processes like steel and cement production significant greenhouse gas sources.

and place them one at a time on a plate to form the silicene paper. he process is like laying bricks,

only these are bricks are the size of a single atom. A 1 centimetre-long chain contains 10 million silicon atoms.
