The installation of building formwork is a time-consuming process, and the cost of formwork (material + labor) can sometimes be as high as 50% of the cost of the concrete structure. During the construction process, it is not uncommon for problems with the building formwork system to cause loss of money and time, and sometimes even serious casualties. The efficient design of these temporary structures plays a vital role in reducing costs and ensuring safety, and plastic construction formwork is one of them.
In the past, construction formworks were mainly made of wood. Therefore, the wooden formwork will naturally be destroyed and discarded after being reused four to six times. However, residual cement and chemical treatment agents on the wood surface of the waste formwork always make subsequent treatment more difficult. Besides, in order to maintain the progress of the industry, various civil and construction industries continue to develop without taking the global temperature rise into account. But even if the wood is used as a raw material for building formworks, the growth rate of forests is far behind the rate of deforestation.
Therefore, any material that can replace wooden formwork, if any, will be an important subject worthy of further study. In recent years of development, new environmentally friendly materials such as plastic construction formworks and aluminum formworks have emerged. Due to its high turnover rate and ease of use, plastic construction formworks ensure the quality of project delivery while reducing costs at the same time. However, according to the survey, the use cost of plastic building formwork is even 40% lower than that of wood formwork.
