When designing our DCL Medical Centre’s we decided to integrate Hollow Core Slabs and the significant benefits both structurally and environmentally… So why Hollow Core? Compared to cast-in-situ, precast uses less cement, less water, less steel, and less labour.
• Concrete is durable and requires no toxic preservatives
• Energy consumption of concrete is extremely low, compared to other construction materials
• The utilization of the thermal mass of the concrete will save up to 35% of the energy required to heat and cool the building even without using fossil fuels, this is through the ability of the concrete to absorb and later release large amounts of heat
• Environmentally friendly production process due to the speed of construction, reduction of noise, dust and dangerous emissions, waste treatment of fresh and hardened concrete residus etc.,
• Reduced use of raw material and rational use of materials (45% saving in concrete compared with a plain cast in-situ reinforced slab)
• Possibility to reuse and recycle at the end of the life cycle
• 28% less primary energy consumption
• 40 to 50% less raw material
• 37.8% less generation of waste
These are just a few of the important points to consider on how Precast Hollow Core reduces a CO2 Carbon Footprint but it is also a very efficient and effective way to build on the standpoint of both the Contractor and the Client. Transfer of material from factories to sites lowers construction costs and increases productivity.
