Study of workability of fresh concrete using high range water reducer admixtures
The main issue in working with fresh concrete is the workability during filling of formwork. One of the problems found in workability is occurence of segregation depending on w/c ratio. Segregation is strongly related to w/c ratio. The fresh concrete is usually considered as a non-Newtonian fluid since it is a mixture of aggregate, cement and water. The flow behaviour of the fresh concrete, a c...
متن کاملProduction of High Performance Concrete Using Admixtures
In this study, it is aimed that production of high performance concrete using admixtures. The admixture is used to resist against to freezing of concrete, and concrete (C20) is produced, and cured in water. 8 samples are tested in pressure, and mean stress is determined as 28 MPa. Remaining two samples are tested with image processing technique, and determined that sample which containing an ad...

15 صفحه اولthe 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...
Effect of Antifreeze Admixtures on Cold Weather Concrete
Kashmir is located in a region where winter temperatures are very low. During the winter months, the temperature in Kashmir is often below 0⁰ C. Generally concrete placed in colder regions with the help of insulated forms as well as heaters to protect freshly mixed concrete against freezing. These practices try to incorporate unnecessary carbon and leads to an disagreeable carbon footprint. The...
