Investigating the properties of bentonite and kaolin
As natural pozzolans, bentonite and kaolin can be used as partial substitutes for cement in concrete production, thus improving its performance. Kaolin, a superplastificant based on cellulose, and calcium carbonate were used as additives and modifiers of printing quality. A total of 15 formulations were Additive manufacturing of Portland cement pastes with

Potential Use of Calcined Kaolinite-Based Wastes as Cement
This paper summarises recent published works on the use of calcined kaolinite waste as partial cement substitutions in concrete, including thermally activated To enhance the compressive strength of the produced cement, kaolin was heated to 650°C for 2 h and then used to prepare samples 6–11 (Fig. 2(a) and 2(b)). Zeolite was added to cement clinker in proportions of 10% and 12% by weight. In these experiments, the kaolin was used as a second additive as 10%, 15%, and 20% of the Application of zeolite/kaolin combination for replacement of

Increasing the kaolinite content of raw clays using particle
Thanks to the rich silica-alumina contents and large reserves in China, coal-series kaolin (CK) (a by-product of coal mining) is promising to be used as an effective SCMs in cement-based materials.Relatively recently, a metakaolin (partially calcined) product is used as a pozzolanic additive in certain cements where high strength is needed. The reactive amorphous alumina and silica in the metakaolin reacts with excess calcium to produce a calcium aluminum silicate which is elongate, thus increasing the strength of the concrete.Chapter 5 Kaolin Applications ScienceDirect

Improvement of the properties of a mortar with 5% of kaolin
The use of K and MK as an additive in the manufacture of mortars and concretes has been the subject of several studies [8], [9], On the other hand, kaolin (K) was used as filler in sand with an adopted content of 5%. Cement. The cement used is an artificial Portland cement CPA-CEM I 42.5This paper presents the characterization of chemical and physical properties of metakaolin obtained via calcination of kaolin at three different temperatures (650˚C, 750˚C and 850˚C) in comparison to that of pure or non-calcined kaolin.

Calcined Clay as Supplementary Cementitious Material PMC
The most commonly used SCM so far is fly ash from coal power plants. However, this additive, which is used in the production of both cement and concrete, is slowly losing its primary importance due to the progressive decommissioning of coal and lignite power plants. As a result, the supply of fly ash will be significantly reduced in the XRF test results show that the content of aluminum in weathered kaolinite sand is 9.8%.
