Effect of a Carboxylic Acid on Rheological Properties of a High Alumina Cement Mortar
In this work, we studied the effect of carboxylic acid on the rheological properties of a high-alumina cement mortar (CH45) produced by the Algerian firm REFRACTAL.The investigated properties are setting time, water consumption, electrical conductivity, pH, density and the compressive strength. The results show a setting time of about 200 min for the acid...
متن کاملThE EFFECT OF METAKOLIN, MICROSILICA AND NANOSILICA ON THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF CEMENT MORTAR
Different mineral admixtures of Indian metakaolin, Iranian silica fume and nanosilica were used to produce high performance mortars. Two different sands types with grain size of 0.015-4mm were mixed with type II Portland cement, polycarboxylate superplasticizer,mineral admixture with 650kg/m3 cement content and water/cement ratio of 0.35. Different amount of cement was replaced by metakaolin or...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولProperties of Mineral Insulating Oils in Service
The infrastructure of the electricity grid and super grid system in the hitherto industrialized world was to a large extent built up in the decades following World War II with a peak in investments around 1960-1980. This means that the flotilla of power transformers is now starting to reach projected lifetime of around 40 years. During the last couple of decades there has also been an ongoin...
متن کاملExperimental Investigation of Toughness Enhancement in Cement Mortar
This paper presents the results of investigation carried out to improve the mechanical toughness of cement mortar. Toughness is a basic parameter which has to be improved in brick walls, concrete roads, machine foundations, dams etc. Materials fails due to an impact force and vibrations resulting in minor cracks and bonding failure between bricks, it leads to failure of the structure. In order ...
