Use of clay as a cement replacement in mortar and its chemical
Highlights In this work I have used clay as a cement replacement. The clay has been activated using quick lime inorder to increase the amount of clay in cement. Hydration evolution and pozzolanic reaction rates of the Quicklime–Clay–Cement (C–C–L) system were monitored. A 3% addition of quicklime was found as optimum dosage both Concrete consumes millions of tons of cement, which causes global warming as cement factories emit huge amounts of carbon dioxide into the atmosphere. Thus, it is essential to explore alternative Partial Substitution of Binding Material by Bentonite

Standardisation of low clinker cements containing calcined clay
Calcined clay reacts in Portland cement mixes to form calcium–alumina–silicate–hydrate (C–A–S–H) and AFm phases that effectively contribute to increase concrete strength [].While calcined clay used in binary blends with Portland cement can potentially produce good quality concrete, using a ternary blend of Portland and ready-to-use form. •Clay bodies can also be produced by mixing Cement, Food additives • is sometimes referred to as China clay because it was first used in China.USE OF CLAYS IN POTTERY ResearchGate

Popular types of cement used in the country BIS
Cement can be of various types like ordinary Portland cement, Portland pozzolana Cement, Portland slag cement, white cement, rapid hardening cement etc., based on their requirement. Presently, we have Indian standards on 15 varieties of hydraulic cement. Some of the commonly used varieties of cement are as follows:Pakistani clays can be utilized as SCM in the production of limestone calcined clay cement (LC 3) due to the country’s vast kaolin clay reserves. This study further supports the viability of producing LC 3 in the nation by providing a thorough analysis of the cement business, known deposits of qualifying clay, and the country’s cement Initial search for low grade clay in Pakistan for producing LC

The Indian Bureau of Mines reports the availability of over 2.7 billion tonnes of high-kaolinite content china clays, currently being used for the production of paper, paints and ceramics in India.Limestone calcined clay cement or LC 3 is a ternary blend of clinker, calcined clay and limestone, usually with the clinker factor as low as between 0.4 to 0.5. Calcined clay acts as a source of reactive pozzolanic component of the ternary cement blend. The extent of reactivity of calcined clay depends on the kaolinite content of raw The Effect of Kaolinite Content of China Clay on the Springer

Clays and Clay Minerals in the Construction Industry MDPI
Clay is a naturally occurring material that can be converted to different clay minerals through thermal treatments, and can be used for the development of different products. Clays and clay minerals have been used for different applications in different sectors. Detailed information regarding the applications of these materials in the A non-exhaustive list of examples of Fe-rich clays and their chemical composition is provided in Table 1.A summary of cement binder precursors is also given in Table 1, which shows that clays can be incorporated in a range of cements.The clays described by Lassinantti Gualtieri et al.
