The effect of three different natural pozzolans from Turkish deposits on the properties of blended cements produced by intergrinding cement clinker with a high volume of natural pozzolan (55 wt.% of the cementitious material) was investigated. The particle size distribution of blended cements, setting time, heat of hydration, and compressive strength of blended cement mortars were determined. Experimental results showed that the hardness of the pozzolanic material strongly influenced the particle size distribution and the related properties of the blended cements by affecting the fineness of the components of the blended product. The early strength of the mortars was strongly affected by the particle size distribution of blended cements, whereas the strength development performance of the mortars was more related to the pozzolanic activity of the natural pozzolan present in the blended cement.

Studies on blended cements containing a high volume of natural pozzolans Uzal, B; Turanlı, Lutfullah (Elsevier BV, 2003-11-01) This paper presents the results of an investigation on the characteristics of laboratory-produced blended portland cements containing 55% by weight volcanic tuffs from Turkey. Volcanic tuffs from two different resources were used. Using different grinding times, particle size distribution, setting time, compressive strength, and alkali-silica activity of the blended cements were investigated and compared with reference portland cements ground for the same time period. For the compressive strength test, a su...
Influence of the shape and roughness of inclusions on the rheological properties of a cementitious suspension Erdoğan, Sinan Turhan; Ferraris, C. F.; Fowler, D. W. (Elsevier BV, 2008-05-01) The influence of particle shape and surface roughness on the rheological properties of cementitious composites (cement paste plus coarse and fine particles) was investigated for mixtures of mortars and laboratory-made aggregates. The coarse particles were monosized spheres and cubes made from mortar, and monosized glass spheres, uncoated or roughened. The fine particles were uncoated or roughened monosized glass mini-spheres. The coarse particle mixtures were tested with a concrete rheometer to investigate ...
The effects of potassium and rubidium hydroxide on the alkali-silica reaction Shomglin, K; Turanlı, Lutfullah; Wenk, HR; Monteiro, PJM; Sposito, G (Elsevier BV, 2003-11-01) Expansion of mortar specimens prepared with an aggregate of mylonite from the Santa Rosa mylonite zone in southern California was studied to investigate the effect of different alkali ions on the alkali-silica reaction in concrete. The expansion tests indicate that mortar has a greater expansion when subjected to a sodium hydroxide bath than in a sodium-potassium-rubidium hydroxide bath. Electron probe microanalysis (EPMA) of mortar bars at early ages show that rubidium ions, used as tracer, were present th...
Influence of degree of saturation on the borehole sealing performance of an expansive cement grout Akgün, Haluk (Elsevier BV, 2000-02-01) The strength measures of expansive cement grout borehole plugs cast in welded tuff cylinders is investigated as a function of the degree of saturation of the plugged rock cylinder and of borehole size. Details on experimental procedure regarding rock cylinder and cement grout preparation, sample curing conditions, experimental apparatus, sample loading, mechanical characterization of the rock, and cement grout, along with procedures for the determination of the sample saturation assuming uniform saturation,...
Laboratory production of calcium sulfoaluminate cements with high industrial waste content Canbek, Ogulcan; Shakouri, Sahra; Erdoğan, Sinan Turhan (Elsevier BV, 2020-02-01) A drawback of conventional calcium sulfoaluminate (CSA) cement production is the use of the costly raw material bauxite as a source of alumina to form the main clinker phase ye'elimite. Replacement of bauxite with industrial wastes can benefit CSA cements economically and environmentally. This study demonstrates the use of high amounts of red mud, a sulfate-rich/high-lime fly ash, and desulfogypsum as raw materials in producing CSA clinkers and cements with better mechanical performances than an all-natural...
