From Wiktionary under the GNU Free Documentation License. Concrete is a construction material composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as 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, employing 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, prestressed concrete and precast concrete are the most widely used types of concrete functional extensions in modern days. From Wikipedia under the
GNU Free Documentation License is concrete not a good idea for tadpoles? does the concrete have chemicals that can kill them? Q. i have some tadpoles in a glass tank. they've started growing legs and now need a place to rest on. we have a big rock of concrete that the tadpoles could climb on, but is concrete filled with bad chemicals for the tadpoles?

If you don't know where the concrete came from or if it was ever in contact with any chemicals of any kind (fertilizer, etc.) I would not put it in the tank. You can buy suitable rocks at the fish store. You will know for sure that they are clean and not have to worry about poisoning your tadpoles.
