The use of fly ash as replacement of sand is an economical solution for making green and denser concrete. The paper presents a concrete mix design procedure for partial replacement of sand with fly ash. Present method could produce additional compressive and flexural strength for concrete with partial replacement of sand with fly ash over control concrete, with higher slump.
RD127 Substitution of Fly Ash for Cement or Aggregate in Concrete: Strength Development and Suppression of ASR 1 The objective of this work was to determine whether the substitution of fly ash for part of the sand (without reduc-ing the cement content) would produce acceptable strength gain in concrete in cold weather while still pro-
concrete is achieved with the combined effect of using Fly ash and Steel Slag as a partial replacement for cement and sand respectively. 2. By this experimental work, the optimum replacement ratio for M20 grade concrete mix are 0% replacement of cement by Fly ash and 20% replacement of sand by Steel
On experimental analysis, it has also been observed that the mortar of the ratio 1:1:5 (cement : flyash : sand) when the replacement of cement is made by flyash, it gives lesser strength in comparison to the replacement of sand by flyash as shown in Tables 4 and 5. Furthermore, the consumption of flyash is also reduced appreciably.

INTRODUCTION 1.1 GENERAL Concrete is the man made material widely used for construction purposes.
Catalogue and hazardous residues list [1], both bottom ash and fly ash from combustion of untreated wood are classified as non-hazardous wastes. This paper is focused on the use of WA in concrete. Use as cement replacement offers environmental gains from lowering CO 2
replacement of sand with Granulated Blast Furnace Slag at 28 days of curing is 10.3% and 10.1% more than that of Fly ash bricks with no replacement of sand. The wet compressive strength for 40% replacement of sand with waste foundry sand and 50% replacement of sand .
Replacing sand with fly ash did not affect the compressive strength, but in a leaching test, complete replacement resulted in Lead (Pb) setting leached above the permissible level. 2. Hooper, R. et al., (2002) focused on setting characteristics of Fly Ash, the effect of fly ash .
Fly ash can replace either the Portland cement or fine aggregate (in most cases, river sand) as a filler material. High fly ash content mixes contain nearly all fly ash, with a small percentage of Portland cement and enough water to make the mix flowable.
Composition of Cement: Portland cement consists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO2) and alumina (aluminum oxide, Al2O3). Composition of Flyash: Depending upon the source and makeup of the...
