Fiber-reinforced cementitious composites (FRCC) have emerged as a promising alternative to traditional cementitious materials due to their enhanced mechanical properties and durability [...]

In this study, the deformation of concrete materials was evaluated using a mechanochromic sensor that detects the discoloration reaction caused by deformation. This sensor was attached by applying the Loctite adhesive to both ends in the longitudinal direction. The process of applying tensile stress to the specimens was videotaped, and the deformat...

High-strength concrete (HSC) uses binders and microfillers with ultrafine particles, such as silica fume. The resulting dense internal hydration structure rapidly decreases HSC humidity, causing shrinkage cracks and affecting internal hydration. Herein, the hydration degree inside high-strength cement composites (HSCCs) was examined using waste gla...

We estimate the mechanical properties of pigment-containing ultra-high-strength cement composites (UHSCCs) and the pigment-induced changes in their physical properties via thermal and X-ray diffraction analyses. Hydrates in samples are analyzed using thermogravimetry. Additionally, the change in color expression with the UHSCC age is examined via t...

Background/Objectives: Recently, research on minimizing the exposure of radon in human environment is under way due to the threat of exposure to radiation, which is a problem in the world. Methods/Statistical analysis: This study is about the production of Radon Radiation Absorbing Hardeners for radon - emitting materials in indoor environment of h...

Background/Objectives: Korea, which is mostly composed of multi-family houses, is paying attention to the importance of sound insulation, insulation, and fireproofing in the environment of multi-family housing.Methods/Statistical analysis: This study is a study on the production of lightweight composite panel core using inorganic by-product, blast...

Recently, Both rapid economic growth and high-quality native finishing materials demand in buildings such as local infrastructure facilities and cultural facilities have increased along with local quarries. So, increasing local quarries and environmental pollution occurred in quarries get the eyes to damaged area of the surroundings. As an example,...
