     1. The reinforcing of concrete is known to be first introduced in France
in 1861. Twenty-five years later German and Austrian engineers developed                              КОНТРОЛЬНОЕ ЗАДАНИЕ №5
formulas for design. Between 1880 and 1890 several reinforced concrete
buildings were erected in the United States. Since 1896 the increase in the           Чтобы правильно выполнить задание №5, необходимо повторить
amount of construction with reinforced concrete has been remarkable.              следующие разделы курса английского языка по рекомендованному

     3. We know reinforced concrete to be a combination of two of the
