The aim of this study is to determine the effect of strategic management implementations on the institutionalization levels. In this regard a field study has been made over 31 stone quarry enterprises in cement producing sector in Konya by using survey method. In this study, institutionalization levels of the enterprises have been evaluated regarding three dimensions: professionalization, manag...

Herein, the performance of graphene oxide (GO) in improving mechanical properties and subsequently reducing the permeability of cement composites used in concrete pavement, is studied. A polycarboxylate superplasticizer was used to improve the dispersion of GO flakes in the cement. The mechanical strength of graphene-cement nanocomposites containing 0.1–2 wt% GO and 0.5 wt% superplasticizer was...

Introduction . One of the problems developing new generation concrete is to ensure rational granulometric composition a mixture cement and fine additives densest packing all particles system. In this regard, paper considers optimization dispersed structure quartz filler, taking into account its specific surface area, concentration in binder water-solid ratio. Materials methods studies, Portland...

Industrial waste generated by the natural stone industry when working with limestone and dolostone is mainly composed of calcium carbonate magnesium carbonate. This mineral composition makes soil stabilization a potential use waste. However, much research must be carried out to fully understand aptitude this for improvement. In work, strength microstructure clayey stabilized using powder lime o...

A novel ultrafine sulfoaluminate cement-based grouting material (USCBGM) has been prepared in the previous research, which had better engineering application performance, such as fast setting and hardening, strength development, stone body microexpansion, other properties compared with traditional cement. However, an particle material, it is also necessary to select appropriate superplasticizer...

During more than three million years, the substance civilization of human society went through the Stone Age, the Bronze Age, the Iron Age, the Steel and Cement Age, and the Silicon Age. At the beginning of the new century, the human society has entered into the Nanomaterials Age, which indicates that a completely new substance civilization of human society has started. This paper analyses and ...

according to the current challenges toward low water use efficiency in agriculture, paying attention to the role of public participation in order to improve irrigation efficiency and effectiveness with useful methods and tools is essential. hence, approaches such as participatory irrigation management has been proposed and applied. after the primary investigation in this study, experiences of i...

Between 17th October and 9th November 2009, the third leg of the Chinese DY115-21 cruise on board the R/V Dayangyihao, confirmed two new hydrothermal fields near the equatorial East Pacific Rise. Five pycnogonid specimens were obtained by deep-sea TV-grab from one of the new hydrothermal vents named 'Precious Stone Mountain' at 1.22°N 101.49°W. These specimens belonged to two new species of the...
