and without fly ash and/or chemical admixtures, was fixed at 280 5 kg/m 3 and the fly ash content as a fine sand replacement at 125 kg/m 3. The target slump was 140 12 mm, likewise obtained by adjusting the amount of mixing water. 474
So we can replace new materials instead of natural sources such as M Sand, fly ash, Metakaolin, etc.Aim of this project is to study the strength properties of the concrete by partially replacing coarse aggregate by waste Cuddapah stones and cement (OPC) with Fly ash.
Sand Fine aggregate Water Cement ratio 0.35 We casted three cubes for each w/c ratio and cured these for four days. And from this we get that M25 that for 10% to 20% replacement of fly ash with weight of cement compressive strength is increases and then if we further increases percentage of fly ash, compressive strength decreases.

Fly ash is most commonly used as a pozzolona in concrete. The use of fly ash in concrete has been encouraged all over the world. 1. Confirmative experimental results on using fly ash as a partial replacement to cement especially in structural components at different levels in the construction society would definitely improve the use of fly ash.
Reject fly ash (r-FA) and recycled glass powder (GP) were examined as replacement materials for the silica sand and cement used to prepare UHPFRC, respectively. In addition, curing UHPFRC specimens at 25C and 90C was investigated to determine differences in mechanical properties.
led to identify fly ash and bottom ash as good substitute for cement and sand in concrete. In this investigation a study is carried on fly ash and bottom ash as cement and sand replacement materials in concrete. Study on Strength of Concrete using Fly Ash and Bottom Ash as a Partial Replacement for Cement and Sand
It is generally agreed that the use of fly ash, particularly as an admixture rather than as a replacement of cement, reduces, segregation and bleeding. If the sand is coarse the addition of fly ash produces beneficial results; for fine sands, its addition may increase the water requirement for a given workability.

However effect of fly ash as partial replacement of cement and sand together with fibers is not clearly available in literatures. Literatures show that partial replacement of cement by fly ash reduces early age strength of concrete. Partial replacement of sand by fly ash together with fiber shall

This study was undertaken to investigate the possibility of
Table No 1 represents quantities of materials required for 1 m3 by a constant 38% of fly ash and water/cement ratio of 0.37 at 0% replacement of sand by GBFS; 40% replacement of sand by GBFS; 40% replacement of sand by GBFS and 10% replacement of cement by MetaKaolin. Mix replacement Cement Kg/ m 3 Metakaolin Kg/ m Fly Ash Kg/ m Sand Kg/ m 3
Cement was replaced by fly ash (FA) and cow dung ash (CDA) in different proportions. Local river sand and potable water was used during preparation of concrete cubes. The cubes were cured for the period of 3 days, 7 days, 14 days, 21 days and 28 days.
VNIT professor develops technology to make sand out of fly ash. western region for setting up a 10 tonne per hour fly ash-sand making plant at NTPC Sipat in Bilaspur district in Chhattisgarh
5) In all grades OPC, fly ash concrete is more durable as compared to OPC concrete and fly ash up to 40% replacement increase with grade of cement. 6) Shrinkage of fly ash concrete is similar to the pure cement concrete in all grades of OPC.
The binder in SCC consists of OPC and fly ash in the ratio of 6535. River sand was replaced by manufactured sand (M-sand) at replacement levels of 20,40,60,80 and . An attempt was made to evaluate the workability and strength characteristics of self compacting concrete with river sand and manufactured sand as fine aggregates.
fly ash replacement were 2.4% and 3.5% higher than that of OPC cement concretes respectively. After 10%, with increasing percentages of fly ash, compressive strength decreased and 50% fly ash
