Plywood is extensively used for shuttering and centering because:
– It provides a smooth finish to concrete.
– It is reusable if properly maintained.
– Phenolic-coated shuttering plywood enhances water resistance.
Detailed Explanation
Plywood is a crucial material in the construction process, specifically during the pouring of concrete. The term 'formwork' refers to the temporary or permanent molds into which concrete is poured. Plywood is often chosen for this purpose due to its ability to provide a smooth surface for the finished concrete, which ensures a visually appealing and structurally sound result. Additionally, if constructed and maintained correctly, plywood formwork can be reused for multiple projects, making it a cost-effective option. Furthermore, the use of phenolic-coated plywood enhances water resistance, allowing for better performance in wet conditions and minimizing the chances of moisture-related damage to the concrete.
Examples & Analogies
Imagine you're using a cookie cutter to shape dough. Just like the cookie cutter molds the dough into a specific shape while providing a smooth edge, plywood formwork shapes concrete and gives it a clean finish. If you clean your cookie cutter and use it again, it's just like reusing the plywood for another construction project, saving both time and resources.
