Influence of Nano-Particles on Characteristics of MetakaolinContained Cement Paste

The influences of nano-ZrO2 (NZ), nano-TiO2 (NT), nano-Fe2O3 (NF) and nano-Al2O3 (NA) additions on properties of the fresh and hardened cement paste in comparison with the fine cement paste were experimentally studied. Mini slump and flow cone tests were conducted on fresh cement pastes. Moreover the compressive and tensile strength of hardened cement paste were measured. SEM micrographs and XR...

Influence of Microencapsulated Phase Change Material (PCM) Addition on (Micro) Mechanical Properties of Cement Paste

Excessive cracking can be a serious durability problem for reinforced concrete structures. In recent years, addition of microencapsulated phase change materials (PCMs) to concrete has been proposed as a possible solution to crack formation related to temperature gradients. However, the addition of PCM microcapsules to cementitious materials can have some drawbacks, mainly related to strength re...
