List five common building materials and state the uses of any 3​

1. STEEL

Steel is a metal alloy of iron and carbon and often other alloying material in its composition to make it stronger and more fracture-resistant than iron. Stainless steels resist corrosion and oxidation because of the additional chromium in their make-up. Because it is so strong compared to its weight and size, structural engineers use it for the structural framework of tall modern buildings and large industrial facilities. Some of its qualities include

2. CONCRETE  

Concrete is a composite material made of fine and coarse aggregate (think gravel, crushed stone, recycled concrete, and geosynthetic aggregates) bound together by a liquid binder such as cement that hardens or cures over time. Portland cement is the most common type of cement, and is a fine powder, produced by heating limestone and clay materials in a kiln and adding gypsum. So Portland cement concrete consists of the mineral aggregate, bound with Portland cement and water. After mixing, the cement hardens or cures into the stone-like material we think of as concrete.

3. WOOD

Among the oldest, or perhaps the oldest, of building materials, wood has been used for thousands of years and has properties that make it an ideal building material—even in the days of engineered and synthetic materials.  

4. STONE

The longest lasting building material available is the one that’s been here for thousands of years: stone. In fact, the most ancient of buildings still in existence in the world are made of stone. It has many advantages, though engineers and architects must make some special considerations when planning a building using stone.

5. BRICK/MASONRY

Masonry construction uses individual units (such as bricks) to build structures that are usually bound together by some kind of mortar. Historically, clay bricks were formed in a mold and kiln-fired. The strongest and most commonly used masonry unit now is a concrete block, which may be reinforced with steel. Glass, brick, and stone can all be used in a masonry structure.

what is this from, i cant tell what language he uses without the piece of literature

taken from the novel “the adventures of huckleberry finn” by mark twain (1884), the author narrates about social issues and norms related to morality, prejudice, and slavery. twain included the excerpt above in order to discuss a moral conflict that huck is in: following the moral values he has received from the society in which he lives. moreover, there are moral issues such as gilt and blame discussed here. in the excerpt above, which is part of chapter xvi, huck faces a dilemma: jim to escape or telling miss watson about jim’s flight. huck feels confused, since by choosing one action or another someone is going to get hurt. both jim and miss watson have him in different ways; jim has protected him and has been very kind with him and miss watson has him with his education. the following sentence is a clear example of the dilemma huck faces when he narrates what his conscience tells him: “what had poor miss watson done to you that you could see her niger go off right under your eyes and never say one single word? ”.
