Replacement of 50% sand with fly ash can save about 0.4 m3 sand. Comparison of cost per N/mm2 compressive strength has shown about 40% to 60% saving in cost. Based on the experimental results, correlations are developed for finding out the compressive strength and cost at 28 and 91 days. Sand was replaced with 10% to 50% of fly ash by weight ...

Effect of coal bottom ash as partial replacement of sand

01/03/2013  Kim and Lee (2011) found that the modulus of elasticity decreased with the increase in replacement of fine and coarse bottom ash aggregates. As shown in Fig. 17, when 100% sand was replaced with fine bottom ash, the modulus of elasticity of concrete decreased by 15.1% from 41.1 MPa to 34.9 MPa.

Bottom Ash - an overview ScienceDirect Topics

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
