The History Of Steel Reinforced Concrete

There is a number of building materials that have been found to be exceptional when used in the construction of buildings. One of these exceptional building materials is steel reinforced concrete. Steel reinforced concrete is a specific type of concrete that has had strong steel rebar or fibers added to it while wet, creating a very strong type of concrete that is able to withstand almost anything when it has dried. Because the results of using steel reinforced concrete are so good for the strength of the building, most modern buildings today use steel reinforced concrete in the construction process.

The advantages of using steel reinforced concrete in building construction was first discovered in the mid 1800's by a man by the name of Joseph Louis Lambot. He found that by adding thin steel bars or steel fibers to concrete, he could greatly increase the strength of the concrete, making it better for use in a variety of applications. In the early years, reinforced concrete was used for making a number of items, such as reinforced garden tubs, road guardrails, and reinforced concrete beams. There were a number of different types of reinforced concrete products on the market because construction firms all wanted to use the product, but no standard method of production had yet been developed.

Over time, many different companies tried their hand at creating the perfect type of steel reinforced concrete. Through much trial and error, the best versions of steel reinforced concrete became widely known while the lesser brands slowly faded away. Buildings that used reinforced concrete in their construction began popping up all over the world, especially in the United States, Canada and Europe. This caused the buildings to have stronger support and last longer, allowing constructors to begin building upward and reducing limitations on weight and height for the buildings. One company in Europe completed over 7,000 buildings using steel reinforced concrete during its first ten years of operation.

In 1878, the first reinforced concrete system was patented in the United States by an American by the name of Thaddeus Hyatt. The Pacific Coast Borax Company refinery, located in Alameda, California, was the first building constructed in the United States using this new system. The popularity of the process skyrocketed in the early 1900's and soon, a majority of the developers in the country were using steel reinforced concrete in the construction of their steel buildings. The process has been refined over the years, constantly changing and improving the formula for making high-quality steel reinforced concrete.

Today, many of the buildings located in industrialized nations use steel reinforced concrete to make the buildings stronger and better able to withstand the ravages of time and the weather. Reinforcing the concrete that will be used on the building adds tensile strength to the concrete, making it much stronger and more flexible that regular concrete, which helps prevent cracking and breakage. Steel reinforced concrete can be used in a number of building applications, including floors, beams, supports, walls, and frames.

 


Benefits of Building a Solid Concrete Home

The idea of having a home that is made completely of concrete may seem unappealing. The concrete building that people see today always feel cold and damp on the inside and the look is just not pretty. With so many other stylish home designs to choose from, why would this even be an option? The reason a solid concrete home should be your first choice is that it can benefit both you and the environment.

Those cold damp buildings that are made of concrete are old buildings that were made without the architectural abilities that we have now. They stay cold and damp because an unfavorable climate got into the building and the concrete serves as such great insulation that it allowed that climate to fester. Modern concrete homes are designed in such as way that the bad temperatures will not get into the home, making them a very comfortable temperature year round. The need for air conditioners and heaters is practically non-existent.

Not only will a solid concrete home cut down your utility bills by a great amount, they'll also lower the amount of work you need to do to keep your home in good shape. Shingles and other types of outer siding require frequent cleaning and maintenance. Concrete doesn't get dirty in the same way that other materials do and they require virtually no maintenance. This is because concrete is very solid and won't easily wear down over time.

Concrete being such a strong material also means that your home will be a lot safer. Whether you live in an area prone to hurricanes or tornados or a dry place that can easily spark fires, you have nothing to fear. Concrete walls are un-phased by winds up over 200 mph and since the material is fire proof, a fire won't take out your home. You will still be safer getting to a safe location but you can rest assured that your home will be there when it is all over.

The thick walls of a concrete home not only make for great insulation but they also keep your home quiet from the loud noises of the busy world outside your home. This is a great feeling that many other types of homes don't have. It's a whole new sense of privacy and seclusion from the world without having to be far away from other people.

Despite the bad reputation the concrete gets as not being an attractive material due to things like pavement or sidewalks, a concrete home can actually be very beautiful. Because concrete is poured and set, it can be made into just about any style home. The colors can range from a white to other light shades of color including a beautiful cream. This type of home is environmentally friendly because concrete is composed of easy to renew materials and can be reused later on. Perhaps the best benefit of having a concrete home is that there isn't any sort of downside to it.

 


What To Do If Your Home Water Well Is Infected With Total Coliform Bacteria

According to the U.S Environmental Protection Agency, coliform bacteria are common in the environment and are often not harmful in of themselves. However, the presence of these bacteria in well water or spring water can indicate that the water may be contaminated with disease-causing agents such as parasites, viruses or bacteria. Since testing for pathogens such as the bacteria, protozoa, and viruses that make people sick can be difficult, total coliform bacteria are tested for instead. Total coliforms are indicators and are more common and easy to grow.

Coliform bacteria are organisms commonly found in soil or vegetation and in the intestinal tracts of warm-blooded animals. This group of bacteria has long been an indicator of the contamination of water and possible presence of intestinal parasites and pathogens. The coliform bacteria are relatively simple to identify, are present in much larger numbers than the more dangerous pathogens, and react to the natural environment and treatment processes in a manner and degree similar to pathogens. By observing coliform bacteria, the increase or decrease of many pathogenic bacteria can be estimated.

E. coli is a type of fecal bacteria that originates from human and animal wastes. During rainfalls, snow melts, or other types of precipitation, E. coli may be washed into creeks, rivers, streams, lakes, or ground water. When these waters are used as sources of drinking water and the water is not treated or inadequately treated, E. coli may end up in drinking water. A presence of E.coli usually indicates a more serious contamination condition than the presence of total coliform alone.

Properly constructed and maintained water wells usually do not test positive for total coliform or E.coli. A presence of coliform in a deep water well usually indicates that the well is under the influence of surface water, or is being contaminated by septic systems, or other industrial or commercial waste water systems.

In some cases new wells or wells that have recently had work performed such as a pump repair, can test positive for coliform due to improper sanitizing of the tools and equipment used during the repairs. If this is the case it is advisable to shock chlorinate the well and pressure system and repeat the test for coliform.

In many cases the water is not contaminated at all but the sample taken was accidentally contaminated during the sampling, producing a false-positive. It is relatively easy to accidentally take a contaminated sample. If you think your water is safe and your well is in good condition, you might consider re-testing the water. Use a sterile bottle and take caution to avoid contaminating the sample by touching the inside of the cap or bottle with your hands, or allowing foreign particles to accidentally get inside the sample bottle.

If your water is contaminated and tests positive for total coliform and/or fecal bacteria you can take one of the following steps:

Boil all water intended for consumption or use a filtration system that can remove bacteria to safe levels.

Disinfect the well, pressure tank and household piping and fixtures thoroughly with chlorine bleach. Wait several days to a week until all chlorine is gone from your system and repeat the coliform test.

Monitor your water quality to make certain that the problem does not recur.

Try to identify the source of the problem (such as a defective well seal, or cracked casing) and fix it.

If the well is too expensive to repair, investigate the feasibility of drilling a new well or install a disinfection unit, which can use chlorination, hydrogen peroxide, ultraviolet light, or ozone to kill bacteria and viruses.

If your water source is a community system on well water there are federal and state laws that apply. All community public water systems, as well as non-community public water systems (public systems that do not serve a residential population such as a gas station or restaurant on a private well), must submit samples for coliform bacteria testing on a regular monthly basis. Failures to submit samples, meet the maximum contaminant level (MCL), and report non-compliance are all violations of the total coliform rule.

The maximum contaminant level is based on the presence or absence of total coliforms in a sample. A very small water system may have one coliform positive sample per month and still remain in compliance with the regulation.

Each state may have its own unique requirements for disinfection and water quality monitoring of public or private water systems. Check with your state water agency to determine what is required in your state.
