To maintain the sustainability of cement and concrete production, there is a trend to use wastes in their production. Soda waste, generated by soda ash production process, and beer waste, generated by beer filtration process, are two locally produced wastes in Turkey and many other countries. The nature of these wastes, mostly their fineness, makes them possible to be used in concrete production, especially as a viscosity modifying agent in the self consolidating type of concrete. In this study, the addition of soda and beer wastes to self consolidating mortar (SCM) and self consolidating concrete (SCC), without any treatment but drying, and its effect on their properties were investigated. Mortar and concrete mixes were prepared using these two wastes as cement or aggregate replacement in various amounts. Tests like slump flow, V-Funnel and L-Box for determining the fresh properties, and compressive strength for the hardened properties of the mixtures were carried out to examine the effects of these wastes on the properties of SCM and SCC. The tests revealed that soda waste takes no role in the strength development of the mixes. However, it is possible to use this waste as aggregate replacement to improve the workability and flowability properties of SCM and SCC. The use of beer waste showed contradictive results. A special treatment for this waste before using it in concrete might be required.

Synthesis of alinite cement using soda solid waste
Güneş, Aslı; Yaman, İsmail Özgür; Öztürk, Abdullah; Department of Cement Engineering (2010)
This study is dedicated to give a production route for a kind of low energy cement called alinite cement using the waste material of soda industry as the main raw material. Soda solid waste, clay and minor amount of iron ore were mixed with certain quantities and burned at six different burning temperatures of 1050, 1100, 1150, 1200, 1350, and 1450 ºC. The resultant clinkers were investigated by mineralogical and chemical analysis. Mineralogical analyses were performed by X-Ray Diffraction (XRD) technique. ...
Cement production by cement-bonded wood particleboard wastes
Yilmaz, Mustafa; Tokyay, Mustafa; Yaman, İsmail Özgür (2016-01-01)
To improve the sustainability of cement and concrete production, there is an increasing trend towards using industrial wastes throughout their production processes. The aim is to find new resources that can be used in any step of cement and concrete production and to find solutions to many problems related to the disposal of wastes. This article discusses the use of wastes generated from cement-bonded wood particle board (CB) manufacturing in cement production. CB waste, which basically contains wood chips ...
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...
Determination of instantaneous breaking rate by Geological Strength Index, Block Punch Index and power of impact hammer for various rock mass conditions
Aksoy, C. O.; Ozacar, V.; Demirel, Nuray; Ozer, S. C.; Safak, S. (Elsevier BV, 2011-07-01)
In mining and construction industries, selection of appropriate excavation method and equipment significantly affects the project feasibility. In the selection, the most important parameters are the geomechanical properties of the rock mass in the excavation route as extensively reviewed in literature. The most widely used geomechanical parameter is uniaxial compressive strength (UCS). However, UCS laboratory test requires time consuming and expensive sampling and core sample preparation processes, which ca...
Effects of separate and intergrinding on some properties of portland composite cements
Soyluoğlu, Serdar; Tokyay, Mustafa; Department of Cement Engineering (2009)
In the production of cement, to increase the cement/clinker ratio and decrease CO2 emission, the most important alternative is to produce mineral admixture incorporated cements (CEM II-III-IV-V) instead of portland cement (CEM I). These cements are usually produced by intergrinding the portland cement clinker and the mineral admixtures. However, the difference between grindabilities of the different components of such cements may cause significant effects on the particle size distribution and many other pro...
