Effect of class F fly ash on the durability properties of.
Fly ash is a by-product from the combustion of pulverized coal, and is widely used as an ingredient in hydraulic-cement concrete. Because it improves many desirable properties of concrete, it is introduced either as a separately batched material or as a component of blended cement. Fly ash reacts with the hydrating hydraulic cement to form a cementing medium.
UTILIZATION OF PAPER WASTE AND FLY ASH IN CEMENT CONCRETE. research on concrete used as extra components in concrete mixes for use in housing projects, to ensure a suitable mechanical strength of the waste paper concrete. Concrete mixes with different materials were ready and fundamental strength features such as compressive strength, splitting tensile, compared with the control mix were.

This research paper seeks to optimize the benefits of using High Lime fly ash in concrete as a replacement for large proportions of cement. High Lime fly ash is a type of sub- bituminous fly ash t hat is self -cementing as well as pozzolanic in nature. High Lime fly ash would be categorized as a Class C fly ash by ASTM because of its high calcium content, however its sulfur content exceeds.
Kaushal Kishore for submitting the paper on Concrete Mix Design with Fly Ash and Superplasticizer. This will not only be a great help to fellow civil engineers but also in saving environment by using the waste fly ash.

The effect of GGBS and fly ash as partial cement replacement was examined on concrete cubes, cylinder and beams. In this research paper we have kept percentage of fly ash for every trial constant except for conventional trial and GGBS was used to replace cement partially from 40% up to 70% while keeping fly ash 25% as constant throughout.
