Eco-Building Material of Styrofoam Waste and Sugar Industry Fly-ash Based on Nano-Technology

Construction world is either directly or indirectly contributed to the environmental degradation that has resulted in global warming and climate change [1]. One of the examples is the use of cement in the construction of which has been accounted for the second largest CO2 emissions after electricity generation, which is around about 930 million tons/year or approximately 7% of the total CO2 emissions (data of Inter-Governmental Panel on climate Change/IPCC) [2]. In addressing this issue, the application of the sustainable development concept that is now known as green construction has been done with concrete constituent materials modification. Another issue about the rising price of oil has resulted in the construction material products including material such as clay bricks and a number of other construction materials. Therefore, research on Green-material products will meet the challenges of economical and environmental aspects. Industrial waste of Styrofoam is used in this study to generate concrete with a light weight and has a good resistance against seepage. While the use of fly ash in this study is intended as a cement substitute material, the use of cement in the concrete mix can be reduced. The use of fly ash from sugar mills Trangkil-Pati, Central Java, Indonesia in previous research is a proof to increase the compressive strength of lightweight concrete produced because it is similar to fly ash [3]. Then, the concept of Nano-technology development will improve the quality of foam-brick performance. (C) 2014 Erni Setyowati. Published by Elsevier B.V.
