Durability of High-performance Concrete with Fly Ash
High-performance concrete (HPC) is usually produced using high quality materials. These high quality constituents drastically increase the initial cost of HPC, hence hindering its more widespread use. Therefore, the main goal of this research project was to produce a low cost enhanced performance concrete or even a low cost HPC, using low quality fly ash and locally available crushed aggregates...

متن کاملDurability Performance of Self Compacting Concrete Incorporating Alccofine and Fly Ash
The cost associated with the application of large volume of cement and synthetic admixtures was one of the major drawbacks of Self Compacting Concrete (SCC), which can be reduced by the use of supplementary cementitious materials (SCM). When the demand of cement reduces, the release of carbon dioxide (CO2) from cement industries will come down, which has a positive impact on global w...
متن کاملCenter for By-Products Utilization DURABILITY OF FLY ASH CONCRETE SYSTEM INCORPORATING HIGH-CALCIUM FLY ASH - A REVIEW
This paper deals with the state-of-the-art information on high-calcium, ASTM Class C fly ash use in cement-based construction materials, such as high-performance concrete, ready-mixed concrete, etc. The major topics included are: properties of fly ash, effects of fly ash inclusion on fresh and hardened concrete, and future research needs. The fresh concrete properties include workability, water...
متن کاملHigh Performance Bricks from Fly Ash
Bricks whose solid ingredient is 100% fly ash have been manufactured. The manufacturing process uses techniques and equipment similar to those used in clay brick factories. The bricks produced were about 28% lighter than clay bricks. The bricks manufactured from fly ash possessed compressive strength higher than 40 MPa. This exceeds some of the best of load carrying clay bricks available by mor...
