Rammed earth is essentially manmade sedimentary rock. Rather than being compressed for thousands of years under deep layers of soil, it is formed in minutes by mechanically compacting properly prepared dirt. The compaction may be done manually with a hammer-like device, mechanically with a lever-operated brick-making press, or pneumatically with an air-driven tamping tool. Dynamic compaction using manual or power tampers not only compresses the soil, but it also vibrates the individual dirt particles, shifting them into the most tightly packed arrangement possible. When finished, rammed earth is about as strong as concrete. Houses built of rammed earth have several advantages over wood-frame construction. The walls are fireproof, rot resistant, and impervious to termites. The solid, 18-24 in (45.72-60.96 cm) thick walls are nearly soundproof. The massive walls help maintain a comfortable temperature within the house, damping temperature swings that normally occur on hot summer days or cold winter nights. When designed and oriented to take the best advantage of solar energy, a rammed earth house can be comfortable with 80% less energy consumption than a wood-frame house. On the other hand, initial construction is about 5% more expensive than wood-frame construction because it is very labor intensive. History Humankind has used the earth itself to build homes and other structures for thousands of years. Jericho, the earliest city recorded in history, was built of earth. Temples, mosques, and churches were built of mud bricks and rammed earth throughout the ancient Middle East. Egyptian pharaohs ruled cities constructed of rammed earth. In the Far East, the technique was used not just for houses, but even for building ancient forerunners of the Great Wall of China. Romans and Phoenicians brought the technology to Europe, where it was used for more than 2,000 years. In the United States, rammed earth construction enjoyed a period of popularity from 1780 until about 1850, when mass-produced fired bricks and sawed lumber became readily available. Houses could be built more quickly and easily with bricks and lumber, which were considered more modern and elegant materials than dirt. The supply shortages experienced after World War I and during the Great Depression brought rammed earth construction back into favor for two decades. Quickbooks 2016 student guide lesson 16.

Learn how to make your own with this article! Diy Rammed Earth Manual How To Build With DirtFrank Lloyd Wright designed houses to be made of rammed earth. When World War II ended, the country faced a large demand for housing, and wartime factories turned to manufacturing building materials that could be used for quicker types of construction. Rammed earth was brushed aside until it was repopularized during the environmentally conscious 1970s. A modified version of the technique, invented by Michael Reynolds, uses building blocks of discarded automobile tires rammed full of earth. These houses not only keep used tires out of landfills, but they can be built by inexperienced, first-time builders. When a homeowner uses the unpaid labor of himself, relatives, and friends, and when he can obtain many of the building materials for free, the construction cost can be held to less than half that of a wood-frame house. For thousands of years, rammed earth construction was taught personally by one generation of builders to the next.
