“…Using these mineral admixtures to replace part of the PC will reduce the cost of SCC, especially if the mineral admixtures consist of waste or industrial by-product. Moreover, the use of mineral admixtures in the production of SCC not only provides economic benefits but also reduces heat of hydration (Uysal and Sumer 2011). Therefore, the attempt is to decrease the cost of SCC production by modifying the composition of the material mixtures through the use of cheaper materials, especially waste compositions (Sharifi 2012;Sharifi et al 2013;Afshoon and Sharifi 2014).…”

In this study, the fresh properties of self-compacting concrete (SCC) incorporating ground waste glass (GWG) as cementing material were experimentally investigated. GWG was used as a partial replacement for cement at replacement levels of 0, 5, 10, 15, 20, 25 and 30% by weight. Reducing the consumption of cement in construction is a major issue in terms of economic performance. Such reduction would also contribute to the environment by lessening the harmful impact of the manufacturing process. Concrete mixtures containing different levels of GWG were prepared with the water to cementitious materials ratio of 0.51. The examined properties included workability, wet density, air content and setting time. Workability of the fresh concrete was determined by using the slump flow, visual stability index, V-funnel, J-ring, L-box and GTM screen stability tests. The results indicate that there is a slight decrease in the wet density of self-compacting ground waste glass concrete (SCGWGC) of nearly 1.37% with the increase of GWG content. The conclusion is that using GWG significantly increases the workability of SCC mixtures. As the GWG increases, the slump flow also increases at a constant amount of water and super-plasticizer, but the concrete flow time decreases. The results showed that it is possible to successfully produce SCC with GWG as cement replacement.

“…Vieira et al [10] describe alkaline oxides fluxes effects, mainly Na 2 O, K 2 O, Fe 2 O 3 , CaO and MgO, which play an important role during firing, reducing the refractory material and promoting liquid phase formation. A number of studies has been developed in order to provide proper destination to such residues such as raw material for Portland cement clinker [21][22][23] and mineral admixture to cement based compounds [20,[24][25][26]. Therefore, this paper aims to study the use of basaltic filler waste as a raw material for red ceramic formulations.…”

Nowadays, environmental codes restrict the emission of particulate matters, which result in these residues being collected by plant filters. This basaltic waste came from construction aggregate plants located in the Metropolitan Region of Londrina (State of Paraná, Brazil). Initially, the basaltic waste was submitted to sieving (< 75 mm) and the powder obtained was characterized in terms of density and particle size distribution. The plasticity of ceramic mass containing 0%, 10%, 20%, 30%, 40% and 50% of basaltic waste was measured by Atterberg method. The chemical composition of ceramic formulations containing 0% and 20% of basaltic waste was determined by X-ray fluorescence. The prismatic samples were molded by extrusion and fired at 850 °C. The specimens were also tested to determine density, water absorption, drying and firing shrinkages, flexural strength, and Young's modulus. Microstructure evaluation was conducted by scanning electron microscopy, X-ray diffraction, and mercury intrusion porosimetry. Basaltic powder has similar physical and chemical characteristics when compared to other raw materials, and contributes to ceramic processing by reducing drying and firing shrinkage. Mechanical performance of mixtures containing basaltic powder is equivalent to mixtures without waste. Microstructural aspects such as pore size distribution were modified by basaltic powder; albite phase related to basaltic powder was identified by X-ray diffraction.

“…Kim et al, [11] Uysal and Sumer [26] reported that when the replacement of mineral admixture increased as the strength loss decreased, the strength loss of FA 35%, was about 6.91%, compared to 10.34% for the FA 15 % specimen. FA increased the compressive strength of concrete at later age.…”
