The Influence of Ambient Temperature on High Performance Concrete

The influence of temperature on the cement hydration process has been the subject of many studies. It has been found that, in the early stages of maturation, the rate of hydration of the alite significantly increases along with an increase in temperature, but later (from 28 to 90 days) it decreases depending on the type of cement [].After a year of This paper presents the effect of temperature on thermal properties of different types of ultrahigh-performance concrete (UHPC). A set of thermal property tests were carried out on UHPC specimens in the 20°C–800°C temperature range for measuring thermal conductivity, specific heat, mass loss, and thermal expansion.Effect of Temperature on Thermal Properties of Ultrahigh

Investigation on the effects of mix water temperature on

In order to investigate the effects of mixing water temperature on mechanical properties of concrete, the compressive strength tests have been conducted. For this purpose, the demolded and cured specimens were tested for 7-day compressive strength according to ASTM C 39 [23]. As it was mentioned before, for the present study Complex wells with high temperature and the presence of carbon dioxide and hydrogen sulfide acid gas require the use of high-temperature and high-density anti-corrosion cement slurry for cementing operations, and conventional cement slurry does not have the advantages of high density, high-temperature resistance, or corrosion Coatings Free Full-Text Study on the Oil Well Cement

Ventilation Prediction for an Industrial Cement Raw Ball Mill

1. Introduction. In the cement industry, grinding is one of the most consuming energy stages in the production units. Around 65% of the total used electrical energy in a cement plant has to be utilized to grind raw materials, coal, and clinker [1,2].Through the process, many variables can affect the efficiency and productivity of - Limestone and gypsum (additions) are taken from a cement mill doser (BK IV) and they dried in an oven at 105°C and 60°C, respectively to facilitate crushing and to prevent clogging in the mill. -Fly ash is taken from a cement mill doser (BK IV). They have a dry fine nature and they don't need any grinding or drying.Effect of clinker free lime and cement fineness on the

Effects of alternative calcium sulphate-bearing materials on cement

Cement Grinding Office (2016) reported that small percent of the total energy supplied to the mill systems is used efficiently, while the rest is converted to heat; the energy produced heats up the ground cement in the mill and can cause the ambient temperature of the mill to rise depending on the initial temperature of the clinker and the In this article, the strength and microstructure development of two low clinker blended cements; limestone calcined clay cement (LC3) and slag-fly ash composite cement (CC) cured at 27 °C and 50 °C are analysed and compared to those of ordinary Portland cement (OPC).
