Solidity is a particularly attractive quality at a time of disorientating change. Concrete is how we try to tame nature. Debate about the aesthetics has tended to polarise between traditionalists like Prince Charles, who condemned Owen Luders brutalist Tricorn Centre as a mildewed lump of elephant droppings, and modernists who saw concrete as a means of making style, size and strength affordable for the masses. Yes, billion with a B. The concrete varied in its aggregate and this allowed different arrangements of materials leading to the Concrete Revolution, in which structurally complicated forms, such as the Pantheon dome were constructed. It links with: Working with cement is safer with waterproof protective gloves and safety glasses. It was hydraulic-setting (water-setting) cement with many material qualities similar to modern Portland cement. The classic example is Japan, which embraced concrete in the second half of the 20th century with such enthusiasm that the countrys governance structure was often described as the doken kokka (construction state). The speed at which these materials are being mixed is perhaps the most astonishing statistic of the modern age: since 2003, China has poured more cement every three years than the US managed in the entire 20th century. Today's concrete is made using Portland cement, coarse and fine aggregates of stone and sand, and water. This "see-through" development is changing the perception of concrete's opaque mass. Both of these amounts of water are small when compared to the original amount of water added to the concrete that does not evaporate to make the hardened concrete. Concrete Examples Dual Coding.
