Nov 01, 1990 This paper shows the results of a 2-year study on the quality of cement-grade bentonite now available commercially. A comparison of laboratory-designed slurries with field-blend samples shows drastic alteration of cement-slurry performance from poor blending procedures and/or poor-quality bentonite, which could cause catastrophic consequences.
Nov 01, 2015 Further characterization of other southeastern Nigerian clays both in their natural state and when beneficiation with Na 2 CO 3, to improve the much desired swellability and rheological properties, could bridge the needed gap by providing local and suitable alternatives to the currently imported varieties. 1.2. Geology of southeastern Nigeria
Most of the local clays tested generally have proven to be Calcium based and did not meet with API rheological values; some possessed standard properties of their own before beneficiation while others did not. However, they can be beneficiated using additives to improve performance. The industry is however yet to gain full confidence

The argillite, represented by AE27, showed the same strength as the clays AE23, AE28 and AE29, even though it is a much more impure clay due to its higher silica amount , referring to the higher quartz content (Table 2 and Fig. 4). However, this good performance only occurred with calcination at 800 C.
May 11, 2021 Despite the poor performance of the economy, Tomes noted that the South African cement sector was continuing to improve its climate mitigation performance in terms of carbon footprint. The local industry was a global leader in developing blended cement technology, making use of waste products such as ground granulated blast furnace slag and ...
Abstract. A process was developed for the beneficiation of a low-rank coal containing relatively high ash (25.97%) and sulphur (5.78%) content. The low-rank sub-bituminous coal of Makerwal Area, Surghar Range, Punjab Province, Pakistan was cleaned by froth flotation technology to get high quality clean coal for commercial applications.
