Value Analysis and Properties Investigation of High Performance Rice Husk Ash Concrete

Abstract:

During recent years, the Taiwan government launches issues of green building , sustainable engineering , carbon reduction and etc. , to promote balance construction and environment ecology. One of the most important materials in those engineering issues is cement which is used widely in construction industry. Cement emits 0.85 tons of carbon dioxide (CO₂) for each ton of cement used in average. This not only causes the waste of energy but also againsts the conception of environmental protection. This research uses the rice husk ash (RHA) which people always regards as the waste material as a pozzolanic material to replace part of cement to make high performance concrete (HPC). Then makes the value analysis and properties investigation for HPC. Based on this research, rice husk (RH) will contain lots of silicon dioxide (SiO₂) after burning into RHA. If use RHA to replace part of cement, it can get appropriate properties of compressive strength and durability. More important is that by replacing part of cement, it not only will reduce the emission of CO₂ and save money but also reach the goal of global village protection on earth.
