Resurface Your Pool with a Great Plaster Job

Wednesday, March 31st, 2010


Resurfacing older pools requires a specialized professional. It enables you to create a water tight seal for your pool. It also referred to as white cement and when properly done can last for more than twenty years. Plaster is known to degrade with time. It usually starts eroding on the corners of the pool. When you notice this happening then you know that plastering is necessary.

Pool plastering is quite a task and require careful planning. However, when you have the right tools and knowhow you can do the plastering yourself. It is rather obvious the first thing that you do when plastering is to drain all the water from the pool. Use a chisel to remove hanging pieces of plaster. Mix the white cement in a container and apply over the pool. After one day, you can apply another coating and apply a water sealant.

Importance of Disaster-Resistant Technology

Sunday, March 28th, 2010


A lot of money is lost due to natural calamities and disasters. Hurricane and earthquake destroy thousands of buildings each year. Researchers are developing some hurricane disasters resistant fasteners. Material that is joined is pulled up over the head. Scientists have placed their research on enlarging the head.

Industry engineers have also used geometry to create the oversized heads. The flat screw shanks will fit in the grooves that are made from the nail rings. They circle the bottom of the nail. It reduces slipping in addition it is kept from slipping from the wood by deep rings. The hurricane nail as it is referred has been proven to give a structure more than two times the actual resistance. It also provides 50% resistance to an earthquake. Even though the hurricane nails can add more cost to your building need they can used on squeaky stairs and floors.

Aluminum Wastes to Be Converted To Commercial Use

Saturday, March 27th, 2010


Researchers all over the world are developing ways of turning aluminum waste material in use products. The industry has been found to produce nearly one million tons in terms of waste product. This usually translates to high cost to the aluminum products manufacturers. This cost is usually in terms of environmental liabilities and lands fill cost.

The aluminum waste is referred to as salt cake. It is skimmed from the aluminum metal during smelting. The researchers have said that they do not view the salt cake a waste product. In addition, they have added that with further processing it can be used to create some valuable products in the market. They are looking at way of developing a way of making waste to be used together with concrete in the building industry. It can be used as foaming agent. It will greatly benefit the industry.

Liquid Granite: Building Material of the Future

Tuesday, March 23rd, 2010


Liquid granite is preferred over concrete for various reasons. It does not explode like concrete when exposed to high temperature. In addition, it had been known to be able to withstand high amounts of temperature for longer periods of time. In addition it mainly made up of recycled material. Liquid granite is so used less amount of cement than concrete.
The product is available from liquid granite limited and was developed at the Sheffield Hallam University. Organizations using granite have given it a four fire rating in case of a fire. Its versatility allows it to be used places where fire safety is paramount. This includes homes and commercial buildings. Liquid granite has received favorable interest from people in the building industry. It is made up of 30 to 70% of recycled materials. Liquid granite will go a great way in ensuring that our homes and buildings are much safer from fire.

Hurricane Proof Buildings

Thursday, March 18th, 2010


The structure and general design of a building plays a major role in protecting a building from hurricane risks. Technology has brought various methods. It helps the building to withstand strong winds and flooding. The technology allows beach front buildings and other buildings to withstand 20 feet of ocean waves. The building is elevated using concrete, steel and wood.

The buildings walls are also built with sheet rock. It allows water and winds to pass through. It is also referred to as gutting. Modern technology has allowed wind loading for the buildings roofing. The building’s roof is anchored to the walls. Hurricane proof buildings also use earth sheltering technology where the earth’s is used against the walls to exert thermal mass. It reduces the heat therefore maintaining a safe haven in case of a hurricane. Concrete is also used for protecting buildings against pounding and flying debris. It is used together with reinforced metal.

Types of Steel Bars

Wednesday, March 3rd, 2010


In general, steel bars are categorized into two. These include deformed and mild steel bars. The mild ones are mainly used to make slab beams that require reinforced cement concrete. They are usually plain and are available in round sections. These sections vary in diameter and can be between 6mm and 50mm. They are usually manufactured as long rods but they can be easily cut or bent without getting damaged.
The deformed type of steel bars usually has ribs, deformations or lugs on the surface. They are used to reduce slipping in concrete. The tensile stress on these bars is higher compared to the mild steel bards. End hooks are not necessary when you are using the deformed steel bars. They usually measure between 6mm and 50mm in diameter. Deformed steel bars are preferred because they limit cracks in reinforced concrete and thus are recommended for use in structural engineering.
