...Mehnaz Dhar; Swapnil Raj; Shashank Bishnoi The efficient selection of clay deposits is critical for the widespread use of calcined clays as suitable supplementary cementitious material ( SCM ). The current initial assessment relies on chemical composition determined by X-ray fluorescence. However...

... kaolinite content of about 40% to produce calcined clay, the durability properties of concrete incorporating calcined clay produced from high-grade kaolinite clay or high kaolinite content (commercially available metakaolin or CC1) and calcined clay produced from a low-grade kaolinite clay (CC2) were...

...Nancy Beuntner; Karl-Christian Thienel Fundamental knowledge about the reaction mechanism of calcined clays in cement and their mutual interaction is important for their assessment as supplementary cementitious materials and the resulting concrete properties. In this study, the hydration of two...

... as an additive or as a partial cement replacement (Hailong et al., 2016 ; Záleská et al., 2018). However, natural pozzolan is conditioned by local geology and is available only in certain regions (Rodrguezcamacho and Uribeafif, 2002). Within this context, calcined clays as SCMs were studied...

...Mohammad S. H. Khan; Quang Dieu Nguyen; Arnaud Castel The aim of this work is to investigate the carbonation resistance of limestone and calcined clay blended cement-based concrete. Two limestone and calcined clay concretes with an average 28 d compressive strength of about 36 MPa were considered...

...Vineet Shah; Anuj Parashar; Geetika Mishra; Satya Medepalli; Sreejith Krishnan; Shashank Bishnoi This study investigates the effect of a new type of blended pozzolan on the hydration, mechanical and durability performance of cement. A blend of limestone calcined clay pozzolan (LCCP) was produced...

... mixing sequences revealed that, in the presence of clay, the adsorption amount of PCE on cement grain surfaces was highly reduced, leading to poor dispersion of the cement particles. 01 12 2016 02 11 2017 02 11 2017 ICE Publishing: All rights reserved 2017 adsorption calcined...

... 04 09 2017 ICE Publishing: All rights reserved 2017 calcined clays Portland cement pozzolans A pozzolanic material is defined as a siliceous or siliceous and aluminous material, without direct cementitious value; however, in the presence of moisture, it reacts chemically...

...Branimir Bratoev; Ivan Doykov; Jordan Ninov; Alexander Lenchev The present work deals with the possibilities for using calcined clays of different compositions and mineral content as pozzolanic admixtures to cement mortars. The optimal burning conditions for each type of selected clay...
