Flexural Behavior of Polyester Polymer Concrete Subjected to Different Chemicals
Polymer concrete (PC) is a composite material prepared by resin and aggregates. Advantages of polymer concretes include rapid curing at ambient temperatures, high flexural and compressive strengths, excellent chemical resistance and low permeability. In this research, a comparative study was performed on degradation of polyester resin concrete in different chemical solutions. Polymer concrete s...
متن کاملUsing Superheated Steam in Drying and Sterilization
Botanicals are received in whole, non-sterile form. BI Nutraceuticals sterilizes, mills, and packages the ingredient in sturdy, safe containers before shipping to customers. Photo courtesy of BI Nutraceuticals Using Superheated Steam in Drying and Sterilization It seems counterintuitive to use water vapor in a process to remove water or to heat materials that can be damaged by moisture, but suc...
متن کاملEffect of compatible solutes on survival of lactic Acid bacteria subjected to drying.
Four strains of lactic acid bacteria were investigated to determine if a relationship exists between accumulation of compatible solutes and the ability of cells to survive drying. Betaine was the major solute found in these lactic acid bacteria subjected to salt stress. Survival of cultures subjected to drying was considerably enhanced when this solute was accumulated by cells.
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
A Coupled Chemo-Elastoplastic- Damage Constitutive Model for Plain Concrete Subjected to High Temperature
A coupled elastoplastic-damage constitutive model taking into account chemo-induced elastoplastic-damage effects for the modeling of coupled chemothermo-hygro-mechanical behavior of concretes at high temperature is proposed in this article. A three-step operator split algorithm for the integration of the rate coupled constitutive equations is developed. Consistent tangent modulus matrices for c...
