“…The grandability of clinker depends on its chemistry and on the conditions, it experiences in burning [12]. Hard burning and high melt Contents resulting from a low silica ratio increase initial grandability since they result in a clinker with low porosity.…”

“…The production of fine grained or dusty clinker is avoided by ensuring that strong nodules of clinker are formed by agglomeration in the kiln. The requirement is met when 90-95 per cent of the void space is filled with liquid melt, which means that Between 15 and 25 per cent by mass of the charge must be melted [12]. Two properties of the melt are decisive in determining the Rate of agglomeration of the clinker and the strength of the resulting nodules, namely its surface tension and its viscosity.…”

“…Due to their elongated habit, Alite crystals pack less densely than the belite crystals, resulting in a clinker which is easier to grind. The grandability of a clinker sample sintered to a density of 3000 kg/m 3 is determined by its fracture energy and the size of the micro cracks present [12]. The number and size of the latter can be related to the cooling regime experienced by the clinker.…”

Cement is one of the most traditional construction materials, as well as, the most widely used cement in the building industry today. The rising costs of energy required for the manufacture of cement and the needed to understand the mechanism of concrete deterioration as well as the necessity of optimizing the use of Portland cement in high quality concrete, emphasizes the fact that understanding of this important building material is essential for correct industry practice. Clinker microscopy is evidently one of the key factors which determine cement quality. In this research cement quality control of Fars Cement factory (SW Iran) were studied by Clinkers Polished sections and Chemical analysis of clinker and Portland cements that were done by Fars cement factory's XRF Lab. Thus, Bouge chemical indices were calculated. Also, Lime saturation Factor, silica and alumina ratios were used to compare the Fars cements and clinker by universal standards and the Ono method was used to investigate the kiln conditions. The Results show the presence of Alite, Belite, Aluminate and quartz phases in polished sections, the type of fuel was from gas fields and the increasing rate of temperature, cooling rate were slow in clinker and burning time of clinker was in long time. Also, Fars clinker and Portland cements have rather conform to clinker and cement universal standards.

“…Fast air-quenching of clinker quickly crystallizes the liquid phase of the clinker, causing stresses that lead to microcracks in the alite crystals. These microcracks make the clinker easier to grind and result in a higher concentration of fine particles in cement (Maki et al, 1993).…”

“…Therefore, there are new technologies of its production that introduce modifications of the properties of a cementitious agent according to its intended use [1,2]. One of them is plasma-chemical technology [3,4] which is characterized by considerable intensity of physical and chemical reactions of clinker formation, high activity of resulting cementitious agent, and allows adjusting the properties of the product, depending on the technological modes [5][6][7][8]. The comprehension and management of hydration process in cement are the basic points of structural materials production with high operational characteristics.…”

Abstract. The calculation of volume concentrations of solid, liquid and gaseous phases of the cement paste produced due to the use of cement that was synthesized on the basis of cement clinker fused in low-temperature plasma was conducted. The changes of kinetic characteristics of the system were identified; they include degree of the pore space filling, the intensity of restructuring, the cement hydration degree at solid and liquid phases, as well as the kinetics of structure adjustment. The quantitative values of changes in the system during solidification relatively to the initial phase composition were obtained; and the comparison with the control samples was performed. Physico-chemical and physico-mechanical research of cement paste was conducted. It was found that during hydration of the test cementitious agent porosity of the system decreases up to 3.6 times relative to the control sample. At the same time, the degree of restructuring of the system increases by 1.2-1.3 times; the degree of filling of the pore space -by 25.6%; the degree of hydration at the solid phase -by 13.5%. This complex increases the strength of the system by 1.7-1.97 times compared to the control samples.
