2021-11-11 Limestone (CaCO3) is used in many industrial processes from an additive in steel, the primary ingredient in cement, and even in food and pharmaceuticals. Gypsum is the primary component of drywall (wallboard and plaster), an additive for cement, an agricultural soil additive, and as a variant of food and industrial additives. The variety of applications for limestone and gypsum, both deposited ...

2018-9-1 Gypsum is a very popular mineral additive used in autoclaved aerated concrete (AAC) technology. In many studies, tobermorite can be synthesized from calcium-silicate-hydrate (C-S-H) phase under hydrothermal conditions in the presence of gypsum, and its impact on the tobermorite content in the AAC blocks has been discussed.

2000-10-1 In this paper, the properties and the behavior of limestone cement concrete and mortar are studied. Portland limestone cements of different fineness and limestone content have been produced by intergrinding clinker, gypsum and limestone. In order to have compatible results, the produced cements were selected to have the same level of strength.

🕑 Reading time: 1 minuteGypsum is a mineral and is hydrated calcium sulphate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement, so its is generally termed as retarding agent of cement. It is mainly used for regulating the setting time of cement and is an indispensable []

2021-11-1 Trials of intergrinding of clinker, limestone, calcined clay and gypsum have shown that the softer nature of limestone and clay and the harder nature of clinker lead to a bi-modal particle size distribution of the cement [29,58]. While the clay and limestone particles may be ground too fine, the clinker particles remain coarse.
