From Wiktionary under the GNU Free Documentation License. Concrete is a construction material composed of cement (commonly Portland cement) as well as other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate such as gravel, limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures. The word concrete comes from the Latin word "concretus" (meaning compact or condensed), the past participle of "concresco", from "com-" (together) and "cresco" (to grow). Concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a stone-like material. Concrete is used to make pavements, pipe, architectural structures, foundations, motorways/roads, bridges/overpasses, parking structures, brick/block walls and footings for gates, fences and poles. Concrete is used more than any other man-made material in the world. As of 2006, about 7.5 cubic kilometres of concrete are made each year—more than one cubic metre for every person on Earth. Concrete powers a US $35-billion industry which employs more than two million workers in the United States alone. More than 55,000 miles (89,000 km) of highways in the United States are paved with this material. Reinforced concrete and prestressed concrete are the most widely used modern kinds of concrete functional extensions. From Wikipedia under the
GNU Free Documentation License Removing concrete slab to build wood deck but worried about water entering basement? Q. So I have a concrete slab attached to the back of my house that is in extremely bad shape (cracked, lifted). I want to add deck off the back of my house but to do so I have to remove the concrete first. What are my options after removing the concrete to keep water out of my basement since the concrete is currently keeping the water from soaking into the ground and getting in the basement. Also, what is the best process at removing the concrete and also disposing of it. Asked by bridoc22 - Sat Apr 5 18:49:20 2008 - - 3 Answers - 0 Comments A. Since your existing concrete is cracked and lifted, putting down a heavy plastic sheet probably would be a good or better than the existing concrete. If possible you might want to slope the soil aways from the house to aid the drainage. You might also cosider a shallow french drain to help with any water that gets near the foundation.

They are made from finely shredded old tires pressed into mats 1/2, 5/8, 3/4 inches thick. They are used in horse stalls and horse trailers to prevent the horse from slipping. They can be hosed clean without the horse slipping on the wet mat.

Q. Does the addition of admixtures and plasticizers to concrete influence it's strength? Asked by suraj k - Thu Oct 18 05:33:35 2007 - - 3 Answers - 0 Comments A. The design mix strength comes from the recipe, and the compressive strength results from the test (usually crushing) to ensure that the recipe was correct. All additives ( and setting temperature) affect the strength of concrete Answered by DavidC - Thu Oct 18 05:49:46 2007 From Yahoo Answer Search: "concrete"  news.google.com PR Newswire (press release) Auctioneers (NYSE and TSX: RBA), the world's largest auctioneer of industrial equipment, will be conducting the World of Concrete benefit auction in Las ... and more » news.google.com PR Web (press release) Revolutionary in form and function, the incablock modular concrete block system is distinctly unique from traditional flat surface blocks. ... and more » news.google.com New York Post Yes, Eli Manning said, he did sign a concrete wall inside the visitors locker room at brand-new Cowboys Stadium following the Giants thrilling 33-31 victory ... and more » From Google News Search: "concrete"  7knots.com 480px x 640px | 125.00kB [source page] Concrete Slab e JPG 22 Oct 2004 12 00 125K Concrete Slab f JPG 22 Oct 2004 12 00 123K Concrete Slab g JPG 22 Oct 2004 12 00 125K Concrete Slab h JPG 22 Oct 2004 12 06 131K  photos.innersource.com 450px x 600px | 66.20kB [source page] Concrete structure  urbanvancouver.com 480px x 640px | 220.70kB [source page] and the heavy metal equipment such as concrete trucks that is used And there s plenty of equipment like this floating around Gastown thanks to the ongoing renovation of the parkade From Yahoo Image Search: "concrete"  mp3freeplay.com unknown Fri, 11 Dec 2009 10:54:38 GM MP3 & music blog aggregator - the best songs and blog posts of music on the web - search and discover something new.
