An English bricklayer made the first portland cement early in the 19th century by burning powdered limestone and clay on his kitchen stove. With this crude method, Joseph Aspdin of Leeds laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine, it ...
Ordinary Portland cement (OPC) locally produced by Oman Cement Company (S.A.O.G) equivalent to Type I cement and conforming to Standard Specification for Portland Cement ASTM C150-22 [44] was used in all mortar mixes investigated in this study. Its chemical composition including main and trace elements are summarized in …

Agreement signed between Oman Cement Company and Sohar Aluminum for the utilization of SPL, that is generated from Aluminum process, in cement manufacturing. The SPL (spent Pot-lining) is a brick that is rich in calcium and silica which have an ended life. The SPL is utilized in cement manufacturing process as a raw material.
Concrete is the most widely used material on earth; It is strong, durable and relatively inexpensive. The cement industry is responsible for about 5–8% of the global man-made CO 2 emissions. On average 0.8–0.9 tons CO 2 is emitted for the production of 1 ton of cement. During the production of cement clinker, calcium carbonate from …
Use of Grinding Aids for Grinding Ternary Blends Portland Cement-Calcined Clay-Limestone Juan Francisco Garcés Vargas, Marlon Espinosa, Yosvany Diaz Cárdenas, Alina Hereira Diaz and Jose Fernando Martirena-Hernandez Abstract This article presents the evaluation of three types of grinding intensifier
Grinding aids are commonly used in cement manufacture to reduce electrostatic forces between powder particles and reduce agglomeration. Alkanolamines are known to also influence the hydration of the aluminate phases in cement.
This project explores the use of grinding aids to control the resulting particle-size distribution of calcined clay and limestone. It was observed that after grinding, calcined clays exhibit a strongly bimodal particle-size distribution, where the clay minerals concentrate mainly in the finer particle population.
