Silanization of SiO2 Decorated Carbon Nanosheets from Rice Husk Ash and Its Effect on Workability and Hydration of Cement Grouts
Autor: Ilayda Berktas, Ojas Chaudhari, Ali Nejad Ghafar, Yusuf Menceloglu, Burcu Saner Okan
Publikováno v: Nanomaterials, Vol 11, Iss 3, p 655 (2021)
Rice husk ash (RHA) having a porous sructure and a high amount of amorphous silica nanoparticles (4 nm) decorated on the surface of carbon nanosheets is a suitable and cheap candidate for the use of a grout additive. In this study, neat RHA and funct

Facile Synthesis of Graphene from Waste Tire/Silica Hybrid Additives and Optimization Study for the Fabrication of Thermally Enhanced Cement Grouts
Autor: Ilayda Berktas, Ali Nejad Ghafar, Patrick Fontana, Ayten Caputcu, Yusuf Menceloglu, Burcu Saner Okan
Publikováno v: Molecules, Vol 25, Iss 4, p 886 (2020)
This work evaluates the effects of newly designed graphene/silica hybrid additives on the properties of cementitious grout. In the hybrid structure, graphene nanoplatelet (GNP) obtained from waste tire was used to improve the thermal conductivity and

An Experimental Approach to the Development of Dynamic Pressure to Improve Grout Spread
Autor: Anastasios Mentesidis, Stefan Larsson, Ali Nejad Ghafar, Almir Draganovic
Publikováno v: Rock Mechanics and Rock Engineering. 49:3709-3721
Dynamic grouting is one of the methods to improve grout spread in rock that have been investigated since 1985. The results were promising, but all tests were performed under noticeable simplifications related to conditions in rock fractures. This stu

Application of Low-Frequency Rectangular Pressure Impulse in Rock Grouting
Autor: Stefan Larsson, Ulf Håkansson, Almir Draganovic, Fredrik Johansson, Sasan Sadrizadeh, Ali Nejad Ghafar
Publikováno v: Grouting 2017.
In order to sufficiently seal an underground facility in fractured rock, it is essential to obtain adequate grout spread into the surrounding fractures. The grout spread itself depends on parameter ...
