Early-age cracking continues to be a significant problem for new concrete construction. Two of the major contributors to such cracking are the heat released by cement hydration during the first few days of curing and the autogenous shrinkage that often occurs during the same timeframe. In this paper, three potential alternatives for reducing these contributions by modifying the concrete mixture...

Because most shrinkage-reducing admixtures (SRAs) significantly reduce the surface tension of a cement paste pore solution, they will naturally influence all physical properties and processes that are dependent in some way on surface tension. Such properties include internal relative humidity, capillary stresses, and freezing point depression, all via the Kelvin equation and its variants (Kelvi...

OBJECTIVES The aim of this study was to verify the clinical effectiveness of decompression in decreasing the size of a cyst. In addition to the different types of cysts, we tried to reveal what effect host factors, such as the initial size of the lesion and the age of the patient, have on the velocity of cyst shrinkage. MATERIALS AND METHODS With the aid of a panoramic view, we measured the s...

Background: Surgical margin determination in malignant lesions is essential and has a direct impact on the choice of postoperative treatments and patient follow-up. Therefore, the processes affecting this variable are worth exploring. This study aimed to evaluate the difference in surgical margin values in excisional skin samples during surgery and after formalin fixation. Methods: A cross-sec...

Nuclear Magnetic Resonance (NMR) is used to study the early-age hydration as well autogenous shrinkage and drying of cement paste with addition coir fibers. The dosage water content fibers are evaluated. results show that added have a negligible influence on kinetics. However, internal curing effect saturated competition induced by dry visualized. As fiber increases, decrease due reinforcing ef...
