Beton Baspar (BetBas) Plastic Formwork System Advantages:
1-Light weight, high speed and easy installation: These forms are produced with 1/3 of metal forms’weight and consequently installation and dismantling would be accomplished in faster pace. Meanwhile, traditional metal forms’ connections transformed to individual 90 degrees rotating levers have leaded to useful widespread performance of this product.
2-Simple transportation: Due to light weight, Baspar Beton panels movement and transportation is simplified in various locations and building floors.
3-To be maintained in different climates: These forms can be maintained in various climates rather than metal and wooden forms based on their impact resistant polymer material.
4-No lubricant application required: Thanks to specific row material, no lubricant or oil is required to be applied on Baspar panel forms. Consequently, concrete exposed surface is quite smooth and no more repair or finishing is needed.
5-Cleaning: Baspar panels can be totally cleaned by water jet while no more detergent is required.
6-Servicingup to 100 times: Based on impact and abrasion resistance of Baspar panels, they can be used in construction up to 100 times if they aremaintained adequately.
7-Environmental friendly forms: The benefit of recyclable row material of Baspar panelsis known as its environmental friendly nature which is possible after service life. Waste material may be sold more than 3-fold of scrap as well.
Use of plastic formworks for concrete construction has many advantages such as durability, cost and flexibility compared to other materials for concrete formworks. Formworks are used to hold freshly placed concrete at its position until it attains enough strength and with the help of formworks concrete can be easily manipulated and various shapes and forms can be constructed. There are different materials which may be used to manufacture formworks for example timber, steel, and aluminum in addition to plastic that offer number of advantages compared to other materials for example durability, cost effectiveness, and flexibility. It is reported that, not only does the construction of formworks takes time but also spent about 20 to 25% of the total cost of the structure. It is one of the major factors that influence the success of construction of any structure in terms of safety, cost, quality and speed. It is for these advantages and benefits of plastic forms that will be discussed in the following sections.
Objectives of Plastic Formworks in Concrete Construction
Form work is not a permanent construction but it requires careful attention to avoid damages of permanent construction. The formwork design and construction are controlled by three principles:
- Safety: It depends on the formwork strength substantially. Life of labors and public might be in danger if the formwork does not possess adequate strength.
- Quality: Concrete shape accuracy and the quality of final finished surface of concrete element.
- Economy: The structural frame, which is the most critical factor during construction, is most crucial cost component.
Advantages of Plastic Formworks in Concrete Construction
Formworks expend large labor force and total cost of the project that is why efforts have made to introducing a formwork system that is cost effective and can be assembled, dismantled and handled easily by labor. There are several advantages provided by plastic formworks in concrete construction:
- Cost effective
- Labor friendly
- Eco friendly
- Low maintenance
- Versatile
Plastic Formwork System
It is manufactured from specific grade plastic that neither placed materials adhered to it nor chemical reactions occur between poured materials and the plastic form and consequently there will be no any patch on the surface of reinforced concrete element. Water or freshly placed concrete leakages from different parts of the form is avoided because of the perfect fitness of various parts of the system. Added to that, it is most labor friendly system because not only does it fit and plugged easily but also it is considerably light weight compare with other types of formwork systems. Nailing and oiling plates are not required prior to concreting because of auto leveling of plugging system that make plates level automatically and consequently it takes about 30% lesser time during installing and dismantling compare with conventional form systems. Additionally, after its utilization, the plastic forms can be cleaned with water easily and if it breaks due to bad handling, low voltage hot air gun is used to seal it. Other formwork materials such as wood, steel, aluminum produce various disadvantages which might outweigh their benefits. For example, the application of wood is considerably costly and create substantial environmental impacts due to deforestation. With regard to aluminum formworks, it can be employed many times but its high cost makes it as not very suitable option to use. In contrary, plastic forms can be recycled and it is environmentally friendly in addition to reduce handling time and great reusability index. Table-1 provides a comparison between plastic forms and other form types. Table-1: Comparison Between Plastic, Traditional, And Steel Formworks.
Different Types of Commercially Available Plastic Formworks
Beton Baspar (BetBas) Plastic Formwork System
It is one type of commercially available plastic form which can be used to construction various structural elements such as walls, columns, and slabs. It provides substantial precision.
Plastic Formworks for Walls
It is used for the construction of boundary walls, retaining walls, shear walls, rainwater drains, flood or storm drain walls, irrigation canals, and in concrete banking.
BetBas Plastic Formwork System
It is produced from composite plastic material and it is the only plastic form that can be employed in both salt and fresh water without damage. Various applications of NOVA plastic forms are shown in Figure-7, Figure-8, and Figure-9.
