This study extended blending proportion range of ordinary Portland cement (OPC) and calcium sulfoaluminate (CSA) cement blends, and investigated effects of proportions on setting time, workability, and strength development of OPC-CSA blend-based mixtures. Thermogravimetric analysis (TGA) and X-ray diffraction (XRD) were conducted …
development of strength of Portland cement mortars with var-ious replacements of pumices are typical of the effect on strength of pozzolanas of medium reactivity. The mortars con-sisted of 1 part of ordinary Portland cement or 1 part of ce-ment plus pumice to 2.75 parts of Ottawa sand by weight (Or-chard D.F, 1973)[2]
Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.
The research group has developed 15 alternatives to Ordinary Portland Cement (OPC) using waste or materials or minerals. Published in Global ... Sweden: Cementa's Skövde plant working on project to optimise its grinding process and reduce the clinker factor of the cement it produces. The project is looked at grinding limestone …
The surface of our crusher rotor is protected by a tungsten-titanium alloy armor design, which reduces stress concentration on the hammer plate and end plate, enhances their strength, and effectively prevents hammer plate breakage and jamming in the crusher. This significantly extends the lifespan of the rotor, doubling the rotor's service life.
