Water absorption by immersion was proportional to the compressive strength. The studies were carried out to find a relation between important physical property and the main mechanical parameter of concretes containing fly ash (FA) in order to develop indications for …
This experimental study is aimed at investigating the characteristics of fly ash concrete by varying the water cement ratio and percentages of fly ash, replacing the cement by weight.
Specific gravity test and fineness test were performed according to IS 1727 ... From the figure, it can be observed that the percentage of water absorption in both fly ash and wood ash replaced cement mortar bricks increases with an increase in percentage of fly ash and wood ash content. It is also absorbed that fly ash replaced bricks have ...
All pozzolanic SCMs do not have the same effect on water requirement to achieve a required flow. For example, in general, fly ash reduces the water requirement due to its spherical particle shape, whereas most other SCMs may increase due to their angular shape or absorptive properties [1].Zeolites and diatomites have been shown to increase the water required due to …
From figure 2 it is clear that the addition of 20% fly ash by volume reduces the water absorption by 32%, while the addition of 50% fly ash lowers the water absorption by 62%.
High-volume (>50%) fly ash (HVFA) is used to partially replace cement in concrete to reduce the greenhouse gas emission, which is beneficial to both cement industry and environment. However, one drawback of using high-volume fly ash cement (HVFAC) is the increase of the water absorption and the reduction of the durability of cement-based materials.
