摘要:

The effect of coprecipitated MgO-Al2O3, MgO-Cr2O3and MgO-Fe2O3gel on the strength retainment properties of magnesium oxysulphate cement based basic castables has been investigated. Incorporation of MgO-Al2O3gel is found to be most beneficial for the improvement and retainiment of both the room temperature and high temperature strengths. SEM studies have been conducted to get an idea about the microstructure of castables cured at room temperature and heated at high temperature.

摘要:

The investigation was carried out to incorporate newly tapped Rajpardi clay, an overburden material of a lignite mine on replacements of extensively used traditional plastic clays like Than and Bikaner in the earthenware type glazed wall tile body composition. Test specimens of five different body compositions incorporating Rajpardi clay were prepared and fired at four different test temperatures, viz. 950°, 1050°, 1100° and 1150°C in an electrical furnace. Dry and fired properties like dry shrinkage, dry MOR, fired shrinkage, fired MOR, percent apparent porosity, percent water absorption, bulk density etc were determined and compared with those of the specimens of a traditional earthenware tile body used as a standard composition.

摘要:

The physico-chemical characteristics of kaolinised rocks occurring at the Northern part of Mulieh village of Jaintia Hills in Meghalaya were studied with a view to finding out their possible industrial applications. The study was conducted on the washed fraction (Grade I) of the clay as obtained by systematic levigation based on the principle of gravity sedimentation. The investigation included characterization of the clay for its suitability in paper, textile, rubber and insecticide industries as per BIS specification. The clay was further evaluated for its application in the field of ceramic whitewares, and this included definite formulation of various types of ceramic products and finding out the thermo-mechanical properties at different temperatures subject to the requirements of the respective products.
