In this study, Cafco Fendolite M-II was used as sample because of its highest quality. Experiments were performed on the synthesized sample and Fendolite M-II. In order to obtain the initial formulation, studies were carried out on the analysis of samples. X-ray Analysis (X.R.D)
Since mica and vermiculite have no setting properties, it is necessary to use cementitious mortars in fireproof formulations. A sieve with suitable mesh can separate large particles including mica and vermiculite from fine particles such as cement and other additives. Identification of components carried out by XRD instrument. X-ray analysis is non-destructive technique which reveals information about chemical composition and physical properties of materials. This technique is based on observing the scattered intensity of X-ray beam hitting a sample as a function of incident and scattered angle, wavelength or energy. The interaction of the incident rays with the sample produces constructive interference and a diffracted ray when conditions satisfy Bragg’s Law. These diffracted X-rays are then detected, processed and counted. Conversion of the diffraction peaks to d-spacings allows identification of the minerals because each mineral has a set of unique d-spacings. Typically, this is achieved by comparison of d-spacings with standard reference patterns.
Figure 1 shows the analysis of M-II sample and Figure 2 shows the analysis of fine particles. Analysis of fine particles performed to identify parameters which affect on properties such as strength, setting, aging, cracking prevention and so on. Device Specifications
