In concrete as a composite material, the workability for placement and strength development with age depend upon the properties of the constituent materials and their combined action. The role of fine aggregate on strength and workability has to be
replacement by coal bottom ash is due to the replacement of the stronger material with the weaker material. Aparna et. al (2015) performed partial replacement of cement and sand using fly ash and pond ash. The grade of concrete is M40, cube and beam specimens are casted and cured for 28 and 56 days. The 20%FA, 18%PA mix will give a
Besides, the sand replacement with a range of 0 to 60% of limestone waste which produced from cutting and polishing activity is mixed in ratio 1:3 and 1:6 in volume and lastly evaluated their

GFRC Mix and Materials The Concrete Network. Sand and cement are typically used at a ratio of about 1 to 1, although some mix designs call for slightly higher cementitious materials content (see quot;GRFC Mix Design,quot; Concrete D#233;cor, June/July 2008).
The strength of cement substituted mortar decreases with the increase in fly ash amount, whereas the strength increases when the fly ash is blended as sand substitute.

friendly construction material. MSand has similar physical amp; chemical properties of Sand. Copper slag is considered as a waste material which could be used in the construction industry as partial substitute of either cement or aggregates. The use of copper slag in concrete provides potential
#0183;#32;The control cement pastes exhibits a rapid increase in the cumulative heat in the first week, followed by a plateau until 28 days. This is consistent with previous findings on cement hydration (Lagier and Kurtis, 2007). Paste with 30% cement replacement by quartz shows almost identical value in the first 2 day as the control paste.

Then the optimum replacement of cement and fly ash was discussed. An experimental results shows the quality of Msand is better than the river sand. The result from its study provided guidelines of suitable utilization of Msand for partial replacement of fine aggregate. It was interesting to note that these methods Could be extended to

partial replacement of cement and fine aggregate for rigid pavement in road construction. In developed countries use of mineral admixtures such as fly ash, silica fume, plastic waste and rise husk ash etc is already adopting to prepare concrete. This includes commercial application on large scale either for addition or for replacement of cement.
Cement Replacement Material. Cement replacement materials are necessary, including coal fly ash, ground granulated blastfurnace slag, silica fume, ground glass natural pozzolans or calcined clay (eg, metakaolin).
