SFCM_09_8:PRACTICABILITY OF USE OF RAMMED EARTH AS COMMON BUILDING MATERIAL

PRACTICABILITY OF USE OF RAMMED EARTH AS COMMON BUILDING MATERIAL KRISTINA TRNKOVA DEPARTMENT OF CONCRETE AND MASONRY STRUCTURES CZECH TECHNICAL UNIVERSITY IN PRAGUE RESUMEN Within the building process many crucial decisions are to be addressed taking into account a whole set of criteria. Among these the most important are price, availability, usefulness, comfort of use and recently also sustainability. In the process of material selection and use, concrete and steel are often considered a safe bet for their well-known behavior, and predictable and stable properties. However, when looked at from the environmental point of view, these materials are often not to be considered green mainly due to high energy consumption and carbon dioxide generation during production, transportation and installation, their somewhat limited recyclability, the use of not renewable input materials, etc. That is why, apart from use of modern materials, it sometimes seems worth to get inspired from the past. Rammed earth is a material with a well-known history, that is local, sustainable and often fully recyclable. This paper presents briefly the history of the material, describes the possible modifications to the originally used material, lists various building techniques and tries to summarize the overall behavior of the material - its physical and material properties, durability, and response to regular and seismic loading. Additionally, an estimate of material behavior when input data are ...

Explosives were congenital into the accurate amount of the accompanying building Part 1 of 2

1. Christopher A Brown has demonstrated that the core columns of the twin towers were infact made of concrete. As a safety measure the designers had hermetically sealed explosives strategically sealed into the concrete. This was top secret. An Excerpt from the statement of Robert L. Parish Sr. On day, as the lead consultant engineer was in my lab talking just about "stuff", I asked him, "Sometime in future, in 50 years or so, how are these Twin Towers are going to be taken down as tall as they were going to be and as tight as land is in a crowded city, without causing fast destruction to other buildings?" He was standing upright. He outstretched his right arm with his palm down. And said, "Bam, bam, bam, bam, bam, bam" as he lowered his hand down one imaginary floor at a time. All the way down to the floor. I knew that we had to certify these commutators to be able to operate continuously for 50 years without service or repair as our part of the contract. He explained that as the buildings are being built, explosive charges are being incorporated into the structures at key floor joint locations. So, that when the first charges are set-off at the top floors, they will take that floor down to the next. And the charges at that floor will take it down to the next floor. This will continue all the way down. The Twin Towers will come straight down like a stack of pancakes. When the buildings get old and no longer useful or profitable to have and maintain, all it will take is a ...

Haiti Orphanage - Bond Building Systems.mp4

This orphanige was constructed in Du Parc, Haiti. It is in a very romote part of the country and the pumping equipment was too difficult to transport. Therefore we used children from the orphanage ranging in ages from 11 to 17 years and they applied the concrete by hand. This classroom was built prior to the recent devastating earthquake. It is near the epicenter and sustained no structural damage. This demonstrates that Bond Building System structures can be built using shotcreet pumping equipment or can be applied by hand with the same results. You get a building that is earthquake resistant and hurricane proof. Quite simply, the strongest building system on the market today.

Building a backyard cine screen

Most of the backyard home-built movie screens I've seen are overbuilt wooden structures that take up a huge amount of room to store when not in use or are flimsy PVC tubing affairs. My answer is to use steel tubing. It is strong, relatively inexpensive, and easy to set up and store. Here is how to build a fast, cheap and solid movie backdrop using 10 foot sections of electrical "black pipe" conduit for the frame. They come in 10 foot sections ready made and are available at Lowes and Home Depot. The advantages of black pipe is it can be setup in 6 minutes. Disassembly is also 6 minutes. It takes almost no room to store. The key is to use half inch black pipe conduit, which is actually about 1 inch across with 1/2" internal size. Here are the parts. You need at least, 8 bungee cords, 12 feet of steel cable, two half inch black pipe elbows and two half inch black pipe connectors. Three 10 foot black pipes. One for the top, two for the sides. 4 ring hanger assemblies so you can add eyebolts and nylon cord if you need to stabilize the sides. I found the screen pre-cut to 6.75 x 9 feet which works out perfectly for the 10 foot black pipe sections. It cost me $29.95 from carlofet.com. I had pocket sleeves put in on the top and bottom, the top sleeve for the top 10 foot long pipe and the bottom sleeve for a steel cable stretched between the two vertical pipes. Tabs were sewn into the side hems so that they could be pulled tight against the side pipes with small bungee cords. To ...

Concrete Sectional Building

Most buildings are sectional view of thinking, such as staircases, but there are also other types such as kennels and other small structures octave. Focusing on quality, if thought is to buy those buildings that can cut plastic easily splinter and break the chain, especially if you are in an area of heavy rain, humidity or heat. buildings of plastic cutting, probably end up cheaper accommodations, but are generally not worth the price All cartridges for them. Metal can be paid, because their corners and edges dangerous, but are often recommended, as long as the rust can be such an annex building to be kept under control.

It 'very important for the proper maintenance of all buildings will be cut, and to ensure that all be reduced to the ground and in the event of an impending storm can be guaranteed. Sectional buildings are made of all types, but the best way is usually a combination of wood, fiberglass,> concrete and metal, each of which can generate a very impressive combination. Although there are many buildings of that section are not getting good reviews from consumers are, there are some that will cost more money, but they are worth it.

These structures higher prices charged more money for a reason. You are probably most developed, while the transition from a higher level of material that has a distinct advantage in finding a building that survives is the BritishTime. It 'also important, according to these models' needs. Inevitably, the prices on all products may vary and take into account its importance for the purchase price or construction.

Sectional buildings are not necessary for all people, but are perfectly suitable for small gardens or limited space of life. A well-constructed building, the cut can only respond to people who are a well-constructed outside the warehouse or laboratory. In the past, people wereavoid cutting of buildings that, because of their appearance, however, there are now many retailers are much more interesting concrete buildings of the section.
