“…These results agree well with the one reported by the Rahmanian et al [33], as the author used 300 to 510 rpm during the mixing process, and the result revealed that at a higher stirrer speed, the granule size distribution seemed to not be affected. In the meantime, it is also assumed that the agglomeration of CIPs was not affected due to the positive influence by bridging agent (HCl) [34].…”

High temperatures and humidity could alter the field-dependent rheological properties of MR materials. These environmental phenomena may accelerate the deterioration processes that will affect the long-term rheological reliability of MR materials such as MR elastomer (MRE). This study therefore attempts to investigate the field-dependent rheological characteristics of MRE with corroded carbonyl iron particles (CIPs). The corroded CIPs were treated with hydrochloric acid (HCl) as a way of providing realistic environments in gauging the CIPs reaction towards the ambient conditions. The corroded CIPs along with silicone rubber as a matrix material were used in the fabrication of the MRE samples. To observe the effect of HCl treatment on the CIPs, the morphological observations of MREs with non-corroded and corroded CIPs were investigated via field emission scanning electron microscopy (FESEM), energy-dispersive x-ray spectroscopy (EDX) and x-ray diffractometer (XRD). In addition, the magnetic properties were examined through the vibrating sample magnetometer (VSM), while the field-dependent rheological characteristics such as the storage modulus of MRE with the corroded CIPs were also tested and compared with the non-corroded CIPs. The results showed that the corroded CIPs possessed hydrangea-like structures. In the meantime, it was identified that a sudden reduction of up to 114% of the field-dependent MR effect of MRE with the corroded CIPs was observed as a result of the weakened interfacial bonding between the CIPs and the silicon in the outer layers of the CIPs structure.

“…Amount increase of injected gypsum in most cases helps to the strength increase. This is probably due to both the formation of primary ettringite with a fiber structure [13] to some extent reinforcing the stone, and the occurrence of hardening accelerator due to exchange reactions Na2SO4. It should be noted that gypsum increase in excess of 3% does not lead to the strength increase for binders with CCB additives and QSCW siftings.…”

One of the effective ways to reduce the material consumption of structures, to save all types of resources due to this, is the transition to porous constructional materials instead of traditional dense materials. In this regard, non-autoclaved gas concrete is of great interest. This material has a high manufacturability and has a good potential for improving the strength properties due to the replacement of traditional portland cement by special composite binders. Available publications confirm the effectiveness and prospects of this direction. An important disadvantage of such works is the fact that the binder indicators and the final cellular concrete characteristics are considered mainly independently. In our opinion, it is more correct to consider at least two structure-forming processes proceeding in parallel and sequentially at different scale levels. Micro level is a stone structure formation based on the composite binder; macro-level is a gas porization of cellular mass concrete. These processes have a great mutual influence on each other, and therefore this article attempts to observe the gassing products effect on the stone hardening based on composite binders, as well as the composite binder makeup on the viscosity change of the molding compound, as an important condition for the formation of high-quality less defective pore structure of cellular concrete.

Celem artykułu jest przedstawienie zagadnienia związanego z wpływem wilgotności powietrza oraz temperatury na wartość współczynnika przewodzenia ciepła tynków perlitowych. Badania laboratoryjne pozwoliły na wyznaczenie wartości współczynnika λ w zależności od temperatury badania oraz wilgotności powietrza (RH). Na podstawie pomiarów wyznaczono sorpcyjność i gęstość materiałów oraz wytrzymałość próbek na zginanie i ściskanie.
