Bottom Ash

Bottom ash is the residue that is fused into heavy particles that drop out of the furnace gas stream (air and combustion gases). Table 10.3 presents the chemical composition properties of bottom ash. These particles are formed at the bottom of the furnace. Bottom ash consists of coarser and heavier particles than fly ash (Torrey, 1978).The color of bottom ash ranges from gray to black.

Cement Composition

The effect of cement composition on cement strength has been studied extensively. 177,182,189,400,420 It appears that this effect is a rather complex one and depends on a variety of factors such as the mutual ratios of clinker minerals, the amount and form of added calcium sulfate and the presence of minor oxides. The available experimental data may be …

Influence of Starkeya novella on Mechanical and ...

Cement-based materials are subject to degradation during their service life. Most of the structural failures have been associated with corrosion of the rebar due to chloride ingress, alkali aggregate reaction, and/or sulfate attack. Microbial activities, especially in waste water collection points such as sewer lines, may compromise the integrity of concrete structures.
