Challenge 1 – The demand for limited resources is increasing
Challenge 2 – The climate is changing faster than ever before
Challenge 3 – Water is in increasingly short supply
Challenge 4 – The population growth and increasing need for energy
MEGATRENDS/GLOBAL CHALLENGES
“Many resources are limited. The only infinite resource is people’s creativity to find solutions to this limitation.”

Leutschenbach School Zurich, SwitzerlandThe facade which is composed of steel structures needed to be protected against fire and reach the fire resistance of R30 and R60. After the evaluation carried out among planners, Steel frame constructor and owner, Sika Pyroplast was chosen to be the right fire protection system for the facade. About 1,100 tonnes fire protection material were applied to the load-bearing steel framework, covering altogether five floors including the structures inside and outside the building.

Related to the concept of sustainability, the use of Portland Cement can be the construction material of choice in order to support:
social needs and economic development by
the attention to environment.In accordance to the megatrends/global challenges:1. Resource efficiency – reducing the resource demand in cement and concrete mix
design2. Climate protection – reducing released CO2 from the manufacture of cement and
transportation process3. Water efficiency – reducing the water demand of concrete mix design4. Energy efficiency – reducing the energy demand of the cement manufacture,
concrete mix design and its applicationIncreasing the volume of recycling process
Rowland Institute Cambridge, Massachusetts, USAThe Rowland Institute at Harvard University in Cambridge, Massachusetts had W.S. Aiken Roofing to deliver a highly sustainable solution with Sika Sarnafil’s system to their roofing problems by installing a green roof and recycling the older existing vinyl roof. The project size is 35,000 square feet.

Ground Water Reservoir Kleine Scheidegg, SwitzerlandThis new-construction project is located at the upper part of Kleine Scheidegg, over 2’100 m above the sea level. Its usable capacity is more than 72’000 m3. This project has difficult conditions because of its location in a high mountain, because the waterproofing membrane should bear big temperature difference: in the morning below 0 degree, while in the afternoon up to 30 degrees.

SUSTAINABLE USE OF PRTLAND CEMENT:RESPONSIBILITY FOR FUTURE GENERATION
Sustainable use of PC means to fulfill social needs and economic development by the attention to the environmental constraint
In accordance to environmentally megatrends/global challenges:
Resource efficiency, climate protection, water efficiency, energy efficiency
However the quality/performance is jeopardy
Use of advanced technology in chemical admixture allows the solution on the sustainable use of PC, while:
Social, economical and environmental solutions as well as concrete quality/performance are satisfied
