“…Since the presence of natural zeolite in mortars increases porosity, it increases the air inside the mortar. After compressive strength tests, Park et al [7] concluded that the increased air content in the mortar decreases the compressive strength. The difference of the mean values of the uniaxial compressive strength, between mortar samples REF1 and REF2, can also be explained by the mineralogical composition of the mortar samples.…”

“…Some natural zeolites display unique physical and chemical features and have a great variety of industrial, building, agricultural, aquacultural and environmental applications. Thus, natural zeolites are used as pozzolana, replacement material in cement production, raw material for lightweight aggregate, raw material for the production of lightweight expanded aggregate, anti-bacteria agent, fungus-resisting material and humidity-conditioning material [2][3][4][5][6][7][8][9].…”

Hellenic Natural Zeolite as a Replacement of Sand in Mortar: Mineralogy Monitoring and Evaluation of Its Influence on Mechanical Properties

HEU-type zeolite-rich volcaniclastic tuff (Hellenic natural zeolite) is used as a raw material for the production of lighter mortars. The addition of natural zeolite in mortar mixtures of sand and Portland cement leads to a decrease of up to 18.35% unit weight. The increase of the natural zeolite proportions increases the porosity and water absorption of the mortar and, at the same time, decreases the uniaxial compressive strength. These variations in the mortar’s mechanical properties are due to the addition of natural zeolite, which causes incomplete hydration of C2S (2CaO.SiO2) and retardation of the mortar’s hardening

“…The capsule needs to be hard and sustainable to avoid being damaged during the concrete mixing and casting process. Park et al [38] discussed the use of zeolite and zeocarbon that some researchers have used for reinforcing microcapsules to enable them to withstand high friction and impact during the concrete mixing process.…”

Thermal energy storage in building integrated thermal systems: A review. Part 2. Integration as passive system

et al. 2016

a b s t r a c tEnergy consumption trends in residential and commercial buildings show a significant increase in recent decades. One of the key points for reducing energy consumption in buildings is to decrease the energy demand. Buildings envelopes are not just a structure they also provide protection from outdoor weather conditions always taking into account the local climate. Thermal energy storage has been used and applied to the building structure by taking advantage of sensible heat storage of materials with high thermal mass. But in recent years, researchers have focused their studies on the implementation of latent heat storage materials that if well incorporated could have high potential in energy demand reduction without occupying the space required by sensible storage. The aim of this study is to review the thermal energy storage passive systems that have been integrated in building components such as walls, ceilings or floors, and to classify them depending on their component integration.

“…Besides Conshield, some literature has investigated many other materials for their use as biocidal additives in concrete. For instance, Park et al [63] examined the effectiveness of Zeolite and Zeocarbon microcapsules on the prevention of fungi growth in concrete. In their study, no fungus growth was observed on the surface of concrete.…”

This paper is intended to conduct a narrative review on the acid corrosion of sewer tunnel concrete in the City of Edmonton-an investigation on the MIC (microbially induced corrosion) mechanism and the potential control methods to improve the sustainability of concrete. Firstly, three categories of main influencing factors were identified for the rate of MIC: hydraulic parameters, environmental factors, and concrete mixture design. Secondly, it is found that the sewer tunnel design plays an essential role in the control of the MIC. Building on that, a review was conducted on eight municipal drainage design standards in consideration of the MIC, indicating a lack of design standards of the flow velocity and pipe material. Finally, an investigation was done for cement-based rehabilitating techniques and materials.
