Abstract

“Insulating Concrete Formwork (ICF) represents a durable and cost-effective construction system widely employed in Europe and North America for diverse building projects. This innovative approach utilizes lightweight formwork crafted from insulating materials to provide support for in-situ concrete wall casting, with the formwork left in place to serve as built-in insulation. The resultant ICF structures offer comprehensive thermal insulation for the building's walls, presenting a seamless surface for the direct application of finishes and cladding systems. As indicated by literature reviews, ICF outperforms conventional building systems, boasting 10% greater airtightness and a 15% cost-efficiency advantage. Furthermore, ICF panel cubes exhibit impressive characteristics, including a 40% increase in compressive strength and a 10% improvement in thermal resistance compared to PCC cubes, demonstrating ductile failure rather than brittle failure. The ongoing project entails the casting of a 150mm * 150mm cube sandwiched between ICF panels of varying thickness (50mm and 100mm). This experimentation aims to evaluate compressive strength, thermal insulation, and water/moisture absorption, while also conducting a comparative analysis of the cost implications between conventional formwork and ICF panels..
