Özet
This work aimed to analyze the thermal, electrical and mechanical properties of cementitious composites (CCs) modified with SNs in dispersed and powdered forms, using experimental design methods and image analysis techniques. It was concluded that SNs have smaller particle size increase thermal conductivity, ultrasonic pulse velocity and splitting tensile strength, and decrease electrical resistance, percentage of water absorption and porosity of CCs. It was found that the optimum usage level of powdered SNs in CCs is 2% by mass because of its tendency to agglomerate. However, it is more advantageous to use dispersed SNs when considering CC performance properties. (C) 2019 Elsevier Ltd. All rights reserved.
