“…Thus, these clays can be considered to be pozzolanic materials in accordance with the NBR 12653 7 standard. For glass powder usage in partial replacement of the fine aggregate in cement composites, the results show that the increase in the compressive strength is a characteristic of materials with a good pozzolanic index 8 . In particular, red clay calcined at 680 to 840 °C presented pozzolanic behaviour in the pozzolanic activity index test.…”

The work presents the characterization of clays from sterile mining of the concentrated phosphatic materials of Araxá in Minas Gerais as pozzolanic materials. Three clays of distinct tones, namely, yellow (YC), red (RC), and intermediate (IC) clays, were used at different levels of excavation depth. The clays were calcined at three temperatures (680, 760, and 840 °C) in a muffle-type electric oven. The pozzolanic activity levels of the calcined clays was measured through the conductivity change in saturated Ca(OH) 2 solutions and also from the result of the compressive failure load achieved by mortars with 35% of the Portland cement replaced with the calcined material. The results indicated that the calcined clays showed a high level of pozzolanic activity and can be used as a partial substitute for Portland cement, thus suggesting the possibility of recovering this sterile material.

“…Waste materials such as fly ash, copper slag, quarry dust, tyre rubber, granite saw dust, steel slag, crushed clay brick powder, China Clay industrial Waste (CCW), etc. resemble the ingredients of concrete, as has been depicted in previous studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The strength of concrete containing 20 % of Saw Dust Ash ( SDA) was determined after 50 days of curing time [1].…”

“…Replacement of fine aggregate by waste glass is considered optimum when up to 20 % of waste glass is added. But this inclusion of waste glass as aggregate tends to decrease workability of concrete considerably [14]. Steel slag (0.7 %) with cement (0.2 %) can be used in stabilization mixes for construction of base courses of pavement structures [15].…”

This paper deals with the performance of China Clay industrial Waste (CCW) as partial replacement of fine aggregate in concrete. The performance of CCW used in concrete has been ascertained by comparing its compressive strength, split tensile strength, flexural strength, acid resistance & heat resistance with conventional concrete. Test results show that natural sand can be effectively replaced with up to 30% of CCW in concrete without changing its durability. Industrijska otpadna kineska glina u betonu U ovom radu je prikazano istraživanje svojstava industrijske otpadne kineske gline (CCW) kao djelomične zamjene za sitni agregat u betonu. Učinkovitost zamjene sitnog agregata u betonu s otpadnom kineskom glinom određena je uspoređivanjem tlačne, vlačne i savojne čvrstoće, otpornosti na djelovanje kiseline i visokih temperatura betona s CCW-om i s konvencionalnim betonom. Rezultati istraživanja ukazuju da se CCW može koristiti kao djelomična zamjena sitnog agregata u betonu do približno 30 % bez ikakvih promjena u trajnosti betona. Industrieller Porzellanerdeabfall im BetonIn der Arbeit wird die Untersuchung der Eigenschaften von industriellem Porzellanerdeabfall (CCW) untersucht, durch welchen im Beton der feine Zuschlagstoff ersetzt wurde. Die Effizienz des Ersatzes des feinen Zuschlagstoffs im Beton durch Abfallporzellanerde wurde durch einen Vergleich der Druck-, Zug-und Beigefestigkeit sowie der Säure-und Hitzebeständigkeit des CCW-Betons und des herkömmlichen Betons ermittelt. Die Untersuchungsergebnisse weisen darauf hin, dass CCW als Ersatz für feinen Zuschlagstoff im Beton teilweise bis zu 30% verwendet werden kann, ohne die Beständigkeit von Beton zu verändern.

“…Considering that soda-lime glass is a non-crystalline ceramic material, and that more than 95% of glass is made from silicon dioxide, sodium oxide and calcium, its addition to cement is interesting from a technical point of view. Research into the use of glass residue in cement has evaluated its use as an aggregate [7][8][9] or as pozzolanic material [10][11][12] . However, the possibility of an alkali-silica reaction is an aggravating factor for its use 12,13 .…”

The use of residues, in partial or total substitution of aggregates or binders in concrete, presents interesting possibilities for obtaining eco-efficient concretes. Research has investigated the use of glass residue in Portland cement composite, whether as an aggregate or a supplementary cementitious material. However, there is still no consensus on the influence of the chemical composition of glass on the behaviour of the composites in which it is used. This paper analyse the influence of this composition on the performance of cement composites produced with microparticles of colourless and amber glass. Pozzolanicity was assessed by direct (Modified Chapelle, electrical conductivity) and indirect test (chemical characterization, X-ray diffraction, thermogravimetric analysis, differential thermal analysis and Strength Activity Index testing. The results show that microparticles of both glass display pozzolanic activity, with no significant differences between them. This confirms the potential for the use of glass microparticles as a supplementary material in cement composites.
