Physico-Chemical Disintegration of Concrete
The purpose of this paper is to list and discuss briefly some of the causes of chemical and physico-chemical disintegration of concrete and to point out some methods that can be used to study these causes. In this paper a distinction is made between physico-chemical (or chemico-physical) and mechanical causes of failure. Processes involving changes in chemical composition (chemical reactions pr...
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...
extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولA Correlation Study on Physico-Chemical Characteristics of Dairy Wastewater
The dairy industry has important to day-today in human life. Dairy industry involves processing of raw milk into products like milk, butter and cheese, etc., and generates 1 to 3 times the volume of milk produced. Knowledge on the physico-chemical characteristics of dairy wastewater is essential in the design, operation, collection and treatment as well as disposal facilities for the effective ...
متن کاملThe Studies on the Physico-Chemical and Organoleptic Characteristic
A highly significant effect (p<0.05) of storage period on physico-chemical characteristics and sensory parameters of Apricot fruit produced in Rawalakot areas of Azad Jammu and Kashmir was investigated at ambient temperature (Relative humidity 60-63% and temperature 28-30 C). The physicoo chemical characteristics such as weight loss, total soluble solids, titratable acidity, ascorbic acid and s...
