The use of carbon fiber grid over conventional reinforcement yields a number of unique properties to CarbonCast components: [7]
Lower weight - When carbon fiber grid replaces steel mesh in the face of concrete products, manufacturers can use less concrete cover to protect the mesh from corrosive elements. Non-corrosive carbon fiber eliminates the need for extra concrete Improved thermal performance - The relatively low thermal conductivity of carbon fiber permits CarbonCast components to provide higher R-values than conventional precast concrete Improved strength - Carbon fiber is four times stronger than steel by weight providing better surface crack control when used as secondary reinforcing and 100% composite action when used as a truss in insulated wall panel Comparable cost - Many applications...

longest tunnel in india under construction
The arduous trek to Kashmir may soon be a thing of the past. A new passage to Srinagar now under construction will not only bring the regions of Jammu and Kashmir closer but will also end the isolation of the valley from the rest of the country.
A number of state-of-the-art tunnels are being dug through the Pir Panjal ranges, among others, for easy roadways and a pioneering railway line both of which will give easy access to the valley.
Even as the railways are planning a 90-km-long network of tunnels, the National Highways Authority of India (NHAI) has undertaken a project to upgrade the present national highway (NH 44) stretch from Jammu to Srinagar into four lanes. The project includes two major tunnels.
The 288-km distance between Jammu and Srinagar will be reduced to 238 km but more...

golden gate bridge detail & video of construction
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, the structure links the city of San Francisco, on the northern tip of the San Francisco Peninsula, to Marin County. It is one of the most internationally recognized symbols of San Francisco, California, and of the United States. It has been declared one of the modern Wonders of the World by the American Society of Civil Engineers. The Frommers travel guide considers the Golden Gate Bridge "possibly the most beautiful, certainly the most
photographed, bridge in the world". [6]

palm Deira detail & video
The Palm Deira was announced for development in
October 2004. [2][8] No timetable for completion has been announced. The first announced design was 8 times larger than the Palm Jumeirah, and 5 times larger than the Palm Jebel Ali, and was intended to house one million people. Originally, the design called for a 14 km (8.7 mi) by 8.5 km (5.3 mi) island with 41 fronds. Due to a substantial change in depth in the Persian Gulf the farther out the island goes, the island was redesigned in May 2007. The project then became a 12.5 km (7.8 mi) by 7.5 km (4.7 mi)
island with 18 larger fronds. [2] It will be located alongside Deira.
By early October 2007, 20% of the island's reclamation was complete, with a total of 200 million cubic metres (7 billion cubic feet) of sand
already used. [2] Then in...
palm island construction details and video
he Palm Islands are artificial peninsulas constructed of sand dredged from the bottom of the Persian Gulf by the Belgian company Jan De Nul and the Dutch company Van Oord. The sand is sprayed by the dredging ships, which are guided by DGPS, on to the required area in a process known as rainbowing because of the arcs in the air when the sand is sprayed. The outer edge of each Palm's encircling crescent is a large rock breakwater. The breakwater of the Palm Jumeirah has over seven million tons of rock. Each rock was placed individually by a crane, signed off by a diver and
given a GPS coordinate. [citation needed] The Jan De Nul Group started working on the Palm Jebel Ali in 2002 and had finished by the end of 2006. The reclamation project for the Palm Jebel Ali includes the creation of a four-kilometre-long...
palm island - Dubai
The Palm Islands are an artificial archipelago in Dubai, United Arab Emirates on which major commercial and residential infrastructures will be constructed. They are being constructed by Nakheel Properties, a property developer in the United Arab Emirates, who hired Belgian and Dutch dredging and marine contractor Jan De Nul and Van Oord, some of the world's specialists in land reclamation. The islands are the Palm Jumeirah, the Palm Jebel Ali and the Palm Deira.
Each settlement will be in the shape of a palm tree, topped with a crescent, and will have a large number of residential, leisure and entertainment centers. The Palm Islands are located off the coast of The United Arab Emirates in the Persian Gulf and will add 520 kilometers of beaches to the cityof Dubai.

space hotel project by NASA
pprSpace tourism is space travel for recreational, leisure or business purposes. A number of startup companies have sprung up in recent years, hoping to create a space tourism industry. Orbital space tourism opportunities have been limited and expensive, with only the Russian Space Agency providing transport to date.
The publicized price for flights brokered by Space Adventures to the International Space Station aboard a Russian Soyuz spacecraft have been US$ 20–35 million, during the period 2001–2009. Some space tourists have signed contracts with third parties to conduct certain research activities while in orbit.
Russia halted orbital space tourism in 2010 due to the increase in the International Space Station crew size, using the seats for expedition crews that would be sold to paying...

Ten largest dams in the world
The following are some of the largest dams in
the world as measured by sheer volume. While
they’re not all necessarily in the “top 10″ in
terms of size, they’re certainly sights worth
visiting.
10. SRISAILAM DAM – INDIA

Located on the Krishna River, the Srisailam Dam
was constructed in the Nallamala Hills in a gorge
that sits approximately 300 meters above sea
level. The dam was is one of the 12 largest in
the country in terms of hydroelectric power
production but was specifically built in order to
provide irrigation for the districts of Kurnool and
Cuddapah – both of which are prone to severe
droughts.
9. NAGARJUNA SAGAR – INDIA
