Cement-lime mortars

open access: yes, 1964
Many important properties of masonry, particularly strength and weather resistance, are affected to a considerable degree by the type of mortar used. One type, generally known as cement-lime mortar, is used extensively in North America and Europe for all types of unit masonry construction.

Permanent Cement Mortar Form Systems

open access: yesJournal of the Korea Institute of Building Construction, 2002
강재거푸집은 근래에 많이 사용되는 거푸집으로서 콘크리트의 완성면이 깨끗하고, 강성과 열전도성이 높지만 초기투자비가 과다하고, 부재의 조립과 해체, 운반을 인력에 의존하므로 시공속도가 느리고, 인력수급상황에 민감하며, 현장에서 가공이 어렵고, 해체작업이 반드시 필요하다는 단점이 있다. 합판거푸집은 콘크리트의 완성면이 깨끗하고, 목재에 비해 설치속도가 빠르며, 가공성과 전용성이 좋지만, 내수성이 불충분하며, 합판의 표면이 취약하여 쉽게 손상되며, 해체작업을 필요로 하는 단점이 있다.

Medicine for the Material World

open access: yesArchaeometry, Volume 68, Issue 3, Page 434-439, June 2026.
ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 20, May 20, 2026.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...
