The purpose of this study was to investigate the reuse of desulfurization slag in cement clinker production and its influence on the formation of clinker phases. The desulfurization slag that mainly contained Ca and Si was identified as non-toxic, and thus it should be suitable to be reused in clinker production. The addition of desulfurization slag increased the melt phase during clinkerizatio...

This paper presents an experimental program on rapid chloride permeability test on lightweight concrete produced from oil palm clinker aggregates. Oil palm clinker is obtained from by-product of palm oil milling. Utilising oil palm clinker in concrete production not only solves the problem of disposing this solid waste but also help to converse natural resources. The parameter of investigation ...

The aim of this paper is to clarify the influence of the clinker SO(3) on the amount of C(3)A. The calculation of the cement phases percentages is based on the research work, Calculation of the Compounds in Portland Cement, published by Bogue in 1929 .The usage of high sulphur fuels, industrial wastes, and tires changes completely the working condition of Bogue because the assumed phase composi...

The paper deals with a formation of artificial rock (clinker). Temperature plays the capital role in the manufacturing process. So, it is useful to analyze a poor clinker to identify the different phases and defects associated with their crystallization. X-ray fluorescence spectroscopy was used to determine the clinker's chemical composition. The amounts of the mineralogical phases are measured...

OBJECTIVE To evaluate the biocompatibility and the setting time of Portland cement clinker with or without 2% or 5% calcium sulfate and MTA-CPM. MATERIAL AND METHODS Twenty-four mice (Rattus norvegicus) received subcutaneously polyethylene tubes filled with Portland cement clinker with or without 2% or 5% calcium sulfate and MTA. After 15, 30 and 60 days of implantation, the animals were kill...

Pyrite cinders, which are the waste products of sulphuric acid manufacturing plants, contain hazardous heavy metals with potential environmental risks for disposal. In this study, the potential use of pyrite cinders (PyCs) as iron source in the production of Portland cement clinker was demonstrated at the industrial scale. The chemical and mineralogical analyses of the PyC sample used in this s...

schnellere Rostgeschwindigkeit, eine kleinere Kühlluftmenge, einen geringeren Klinkerdurchsatz oder eine größere Partikelgröße vermieden werden. Abstract The moving grates, or travelling grates, are widely used in industries. For the purpose of product quality improvement (in quenching of clinker), energy consumption reduction (in pre-heating of limestone), emission control (in waste incinerati...

Pozzolans have been used to improve the some properties of concrete and also to reduce the cost of producing cement. Many researchers investigated pozzolanic cements, which were mostly made with kind of artificial or natural pozzolans. While the most recent investigations on pozzolan containing cements study the effect of pozzolan type, replacement amount and fineness, this study was investigat...

Energy balance was performed on the clinkering process when utilizing oil shale as a source of both raw materials and energy. The balance was also compared with the typical energy requirements for production of Ordinary Portland (OP) Clinker. The use of Jordanian oil shale can reduce energy requirements in production of OP clinker by 15–20%. This reduction is due to two factors: lower clinkerin...
