Synthesis And Characterization Of Rankinite From Rice Husk Ash And Eggshells
Rankinite has been used in production of building materials such as cement or concrete because of its lower calcination temperature and less fuel consumption than OPC. Rankinite is usually synthesized from calcium oxide and silica. Therefore, rankinite is synthesis from rice husk ash and eggshells...

| description | Rankinite has been used in production of building materials such as cement or concrete because of its lower calcination temperature and less fuel consumption than OPC. Rankinite is usually synthesized from calcium oxide and silica. Therefore,
rankinite is synthesis from rice husk ash and eggshells as source of silica and calcium oxide, respectively in this work. The aim of this study is to determine the effect of
composition ratio CaO:SiO2 of 3:2 and 1:1 and sintering temperature of 950˚C, 1050˚C and 1150˚C towards the rankinite synthesis from rice husk ash and eggshells. Silica and
calcium oxide are first extracted from the rice husk and eggshells. The silica and calcium oxide are then calculated by mole ratio, milled and pressed into pellets. The
raw materials were analysed with X-ray diffraction (XRD), X-ray fluorescence (XRF) and particle size analysis (PSA). The mixing sample of rankinite is analysed via XRD, Fourier-transform infrared spectrometry (FTIR), Scanning electron microscope (SEM), PSA, linear shrinkage test, density and porosity test and compression test. After characterization, rankinite was synthesized successfully via both composition ratio
CaO:SiO2 (3:2 and 1:1) and all sintering temperature. Density and diametral tensile strength are directly proportional to sintering temperature while hardness shows inversely proportional to the sintering temperature. Composition ratio CaO:SiO2 at 3:2 shows higher density and porosity, higher diametral tensile strength and higher hardness compared to composition ratio 1:1. Overall, rankinite synthesized at composition ratio 3:2 and sintered at 1150 ˚C shows most relevant properties with OPC hence most suitable to replace as clinker. |
