Background of the study

Most of the materials being used in building infrastructures like cement, steel, sand and gravel, steel bars are common nowadays that people stick to the old ways. In the long run, buildings which are built to these kinds of materials have less durability. Most engineers find ways to lessen building damages caused by natural calamities. Polystyrene was accidentally discovered by a German apothecary, called Eduard Simon, in 1839. When his newly discovered chemical “Styrol” or “Styrol Oxide” which was an oily substance he had isolated from a natural resin, hardened after a few days, he assumed it had oxidised. In 1845, English chemist John Blyth and German chemist August Willhelm von Hoffmann proved that the same reaction took place in the absence of oxygen, showing that it was not oxidation. They named it “Metastyrol”. Then, in 1866, Marcelin Berthelot demonstrated that the hard material was actually a polymer. The problem was that the monomer was too unstable and tended to turn into the polymer before it should, preventing useful application of polystyrene, as it came to be known in the midtwentieth century.

As we all know Polystyrene foams are good thermal insulators and are therefore often used as building insulation materials, such as in insulating concrete forms and structural insulated panel building systems. With the unique characteristics of the polystyrene blocks, buildings can be constructed faster and cheaper than normal brick and mortal buildings from one storey to multi-storey. The blocks can be used in residential, industrial and commercial construction projects. The polystyrene blocks are stacked and then the forms are filled with concrete. Building with blocks is a lot like building with the toy blocks. Once in place the blocks are used to give structure. As soon as the concrete is casted in the blocks, stability is gained. Rebar’s are placed in the foam blocks before the concrete is casted. The steel bars are used for reinforcement of the structure. A specific method is used for the filling of the polystyrene blocks to prevent overflow or too much expansion. Once the concrete has become firmer, the units can be left in the exact spot. As such the foam structures are used as empty bricks and then filled with concrete. The

polystyrene is not removed afterwards simply because the material forms a sound insulation as well as act as thermal insulation. Electrical wiring and plumbing pipes can be inserted in the polystyrene. This ensures quicker installation of electricity and plumbing pipes in a building. With the interlocking polystyrene block system an exceptionally strong, yet, well insulated building can be constructed faster than is possible with the normal brick and mortar method. The steel connectors ensure flexible reinforcement of the structure.

Since then, some engineers start to use polystyrene blocks as permanent insulation in buildings. The blocks are energy efficient and ensure optimal insulation not only for walls of buildings, but also the roofs and even floors. Lightweight polystyrene foam provides excellent thermal insulation in numerous applications, such as building walls and roofing, refrigerators and freezers, and industrial cold storage facilities. Polystyrene insulation is inert, durable and resistant to water damage.

Statement of the Problem In constructing a building it should have good materials to be used. If the materials are

poor, a building could easily fail and it makes a threat to people’s safety. The state aims to answer the following questions: 1. What are polystyrene blocks? 2. What are the uses of polystyrene blocks? 3. What is the benefit of using polystyrene blocks? 4. How many percent of the hardware and construction supply stores in Ozamis City have or sell polystyrene blocks? 1.1 What are their reasons for not selling or making polystyrene blocks available in their respective establishments?

Objectives of the Study Since older buildings we see right now have physical evidence caused by damage in

natural disasters like cracks, debris falls, and sometimes even the building itself collapse. The main objective of this study is to let engineers know that polystyrene blocks are one of the good materials that can be used in building construction and its effectiveness and efficiency. The specific objectives of this study is listed below: 

To determine the polystyrene blocks



To determine the use of polystyrene blocks



To determine the benefits of using polystyrene blocks



To determine the percentage of polystyrene blocks which are present in the hardware and construction supply stores in Ozamis City

Significance of the Study In construction the major consideration is the materials. However, high-quality

construction materials don’t come cheap. And with rising economic pressures, the cost of construction materials has been steadily on the rise. In light of this, it has been the collective goal of many to discover alternatives to the most common materials used in construction. These alternatives should possess relatively the same quality and durability to those of conventional materials, but at much lower price. The results of this research study may be beneficial for the following:

Architects- The result of this research helps architects in design wise decision. They would be able to make new designs.

Engineers- The results benefit the engineers in building construction. They will acquire knowledge about polystyrene blocks being used as one of the constructing materials. A safer and efficient construction projects.

Future Engineers- The result will benefit the future engineers. Students who study engineering course gain more knowledge about using polystyrene blocks as one of the constructing materials.

Scope and Limitations

This study mainly focuses on the building infrastructures being used in engineers and to help promote safety to both the building and the people who lives in it. This research is limited to engineers and architects who work on finding and improving the safest and efficient way in building infrastructures.
