Abstract

Microwave incinerator as one of the modern incinerators is proposed to produce amorphous Microwave incinerated Rice Husk Ash (MIRHA) with high pozzolanic reactivity thus can significantly enhance concrete properties. Analyses on the MIRHA with various burning temperature, the temperatures used were 300°C, 400°C, 500°C, 600°C and 800°C. To determine the physical and chemical properties of MIRHA with various burning temperature were also conducted through X-ray diffraction (XRD), X-ray Fluorescence (XRF), scanning electron microscope (SEM) and mechanical properties test. The results showed that the MIRHA at 300oC could be used as a cementitious material with optimum OPC replacement at 20%. It was found that MIRHA foamed concrete at 300oC achieved more than 100% higher strength compared to foamed concrete without MIRHA.

Abstract

This study aimed to know water retention on concrete using paper filter Whatman No.42. The study was conducted as experimental in laboratory by making two types of specimen with different Water Cement Ratio (WCR); 0.5 and 0.6. Each specimen was immersed for 28 days. Next step was finding the time of consistency water content on specimen and paper filter. Then, water retention could be measured. As a validation of water retention measurement, so the results were compared with saturated salt solution method in dessicator.  This study used NaCl, KCl, and H2SO4 as saturated salt solution. The results of water retention measurement were shown in graphs

Abstract

Sustainable development is a concept in green building, which involves ecological, social and economic objectives. It requires to sustain the integrity of resources exploitation, the orientation of technological development and the direction of investments. Concrete is most used construction material worldwide. However, the concrete also brings a great environmental cost. The billions of tons of natural materials mined and processed every year and huge enormous amounts of energy required to produce the cement as well as 7-8% of CO2 released into the atmosphere in the cement processing. This paper discusses the various efforts to improve the concrete environmental friendliness or as a green building material. The most potential successful effort in this matter is utilize local substitutes for cement, especially those that are byproducts of industrial processes, like fly ash, ground granulated blast furnace slag and silica fume
