as regards if curing stops for some time and then resumes again, then strength gain will also stop and reactive, in this study with choose suitable curing conditions after improper first curing (recurring) for normal and silica-fume concrete, effect of this curing conditions on strength and permeability was investigated. the results from tests such as compressive strength, capillary water absor...

Structural concrete exposed to marine environment deserves special attention as the diffused sea salts chemically react with harden cement matrix and forms various expansive/leachable compounds leading to loss of material, strength, cracking, spalling etc. This study cover the effect of sea water on the specimens cast from two grades of concrete exposed to simulated marine environment over a ye...

This study investigated the influence of modulated photo-activation on axial polymerization shrinkage, shrinkage force, and hardening of light- and dual-curing resin-based composites. Three light-curing resin composites (SDR bulk-fill, Esthet X flow, and Esthet X HD) and one dual-curing material (Rebilda DC) were subjected to different irradiation protocols with identical energy density (27 J c...

In order to investigate the effects of microwave curing on the microstructure of the interfacial transition zone of mortar prepared with a composite binder containing glass powder and to explain the mechanism of microwave curing on the improvement of compressive strength, in this study, the compressive strength of mortar under microwave curing was compared against mortar cured using (a) normal ...

Abstract The objective of this study was to investigate the effect salt concentration on meat iridescence in cured cooked pork products. In addition, influence nitrite and pigmentary color its visual macroscopic perception ascertained. Sample cubes from pigs M. longissimus thoracis et lumborum were salted with either NaCl (20 g/kg, 40 g/kg) or curing (6 20 subsequently cooked. Control samples n...

Microsilica concrete was prepared with a water-binder ratio of 0.35. Microsilica was used as a 10% replacement of cement by weight. Cylinder and cube specimens were cast for testing different hardened properties of the concrete. Three curing methods such as water curing, wrapped curing, and dry-air curing were applied at 20±2 C to cure the cylinder and cube specimens until the 0 day of testing....

Refractive index control of benzocyclobutene (BCB 4024-40) is achieved by facilitating different conditions during the thermal curing of BCB film. Refractive index (RI) change of 1.49% is obtained with curing of BCB film using an oven, while the RI change is 0.1% when the BCB is cured using a hotplate. The two different curing methods exhibit a temperature dependent refractive index change of t...

PURPOSE The aim of this study was to compare postoperative sensitivity following placement of posterior composite restorations using the fast- or step-curing modes of an LED curing light. MATERIALS AND METHODS Thirty patients participated, with each having two homologous contralateral posterior teeth with Class II carious lesions. One restoration was cured using the fast-curing mode of the LE...
