Use of perlite as a pozzolanic addition in producing blended cements
Erdem, Tahir Kemal; Akgül, Çağla; Tokyay, Mustafa; Erdogan, Turhan Y (2007-01-01)
There are similar to 6700 million tons of perlite reserves in the world and two thirds of this amount takes place in Turkey. Although perlite possesses pozzolanic properties, it has not been so far used in producing blended cements. This study focuses on the use of natural perlites in blended cement production. For this purpose, after examining the suitability of the perlites as pozzolans and their case of grindability, 16 types of blended cements having 320 m(2)/kg or 370 m(2)/kg Blaine fineness were produ...
Use of boron compounds as binders in iron ore pelletization
Sivrikaya, Osman; Arol, Ali İhsan (2010-05-01)
Low grade iron ores with impurity gangue minerals containing silica and alumina must be upgraded to an acceptable level of iron content. Concentrates, due to their fine sizes, are not suitable to be directly charged to the iron-making processes such as the blast furnace or the DR-plant. Hence, an agglomeration technique should be applied to fine concentrate. The most commonly employed one is pelletizing in iron ore industry. In pelletizing, iron ore, water and a binder are balled in a mechanical disc or dru...
Use of perlite as a pozzolanic addition in blended cement production
Meral, Çağla; Erdoğan, Turhan Y.; Department of Civil Engineering (2004)
Perlite is a volcanic glass which has high amount of silica and alumina. Those properties make it a candidate, if finely ground, for being used as a pozzolan. The studies on the pozzolanic properties of perlite are very limited, and none of them has dealt with the use of perlite in the blended cement production. The aim of this study is to investigate the pozzolanic properties of perlite, and if appropriate to investigate perlite̕s usability in blended cement production. For this purpose, perlites from two ...
Use of boron based binders in pelletization of iron ores
Sivrikaya, Osman; Arol, Ali İhsan; Department of Mining Engineering (2011)
Bentonite is the most preferred silicate-based binder in iron ore pelletizing. However, it is considered as an impurity due to its high SiO2 and Al2O3 content. The iron-making economy is adversely affected by the addition of bentonite or other silicate-based binders. In recent years, impurity-free alternative binders have been tested in order to replace bentonite or to lower the bentonite dosage. Organic binders yield good quality green and dry pellets. However, they fail to impart enough mechanical strengt...
Use of borates as an activating agent for drilling mud bentonites
Toka, Bülent; Arol, Ali İhsan; Department of Mining Engineering (2008)
In drilling technologies, Na-bentonite-water mixtures are used as drilling mud. As the reserves of sodium-bentonite decline, calcium or low-quality bentonites are activated with inorganic salts and/or treated with different types of polymers as an alternative to Na-bentonite. The quality of such bentonites, commonly referred to as extended bentonite may deteriorate under severe drilling conditions, such as; bacterial activity, high temperature etc. It was considered that borates could prevent the deteriorat...
