Curing with Shrinkage-Reducing Admixtures Beyond drying shrinkage reduction
Shrinkage of concrete, along with the cracking that often accompanies it, has been a continual concern of the concrete construction community.1,2 In the past 20 years or so, numerous shrinkage-reducing admixtures (SRAs) have been developed with the goal of reducing drying shrinkage and delaying or preventing cracking.2-6 Most SRAs function by reducing the surface tension of the pore solution in...
متن کاملEliminating cracking during drying.
When colloidal suspensions dry, stresses build up and cracks often occur -a phenomenon undesirable for important industries such as paint and ceramics. We demonstrate an effective method which can completely eliminate cracking during drying: by adding emulsion droplets into colloidal suspensions, we can systematically decrease the amount of cracking, and eliminate it completely above a critical...
متن کاملCracking in drying latex films.
Thin films of latex dispersions containing particles of high glass transition temperature generally crack while drying under ambient conditions. Experiments with particles of varying radii focused on conditions for which capillary stresses normal to the film deform the particles elastically and generate tensile stresses in the plane of the film. Irrespective of the particle size, the drying fil...
متن کاملThe Effect of Drying Kinetic on Shrinkage of Potato Slices
Objective: Potato is the fourth important food crop after wheat, rice and maize. Shrinkage of food materials has a negative consequence on the quality of the dehydrated product. The main objective pursued in this paper is to investigate the shrinkage amount of potato slices during drying process using vacuum-infrared method. Methods: In this work, the effect of the infrared radiation...
متن کاملPlastic Package Moisture-Induced Cracking
With the older “through-hole” technology packages such as the Dual In-line Package (DIP), soldering to printed circuit boards was accomplished using a wave solder. The DIP leads went through holes in the printed circuit board, where they were exposed to molten solder during the mounting process. The DIP’s body was never subjected directly to the solder melt, because it was protected from the he...
