Abstract -Cement is the second most consumable product by human beings. By producing tonnes and tonnes of cement it leads to 7% of global pollution. One of the practical solutions to economize cement is to replace cement with supplementary cementitious materials like fly ash and coir powder for reduce the self weight of concrete. Majority of fly ash produced is of Class F type. Fly ash is generally used as replacement of cement, as an admixture in concrete. Based on the experimental results, the initial strength of 70% replacement of coir powder has increased in 7 & 28 days compressive strength. But it attains the excessive strength at 90 days. Owing to that, replacement of cement materials by coir powder content will attain initial strength with lower self weight.
high volume fly ash concrete system. High volume fly ash concrete is a concrete where in 50 to 60% fly ash is incorporated.
1.2 Coir Powder
Key Words: coir powder, cement, fly ash, experimental test.
Laboratory experiments were conducted to study the physical, chemical and microbiological properties of coir. The addition of coconut fiber to coconut dust increased the airspace (Air at - 10cm tension) but reduced easily available water. The water buffing capacity was lower in coir than in peat. Levels of air space, however, varied considerably. It should be possible to get predetermined levels of airspace by mixing the appropriate levels of fiber to coconut dust. In incubation studies carried out over 20 weeks there was a significant nitrogen retention in one case probably due to the age of coir but the addition of fiber.
1.INTRODUCTION
1.3 Need For The Project
Concrete is the most important material used for construction. In the modern world, the use of concrete has been increasing and it is being widely used for the construction of most of the buildings, bridges etc. Hence, it has been properly labeled as the backbone to the infrastructure development of a nation. Ordinary Portland cement (OPC) is by far the most important type of cement. One of the most important benefits is the faster rate of development of concrete to improve the fieldpaper.
• To increase the initial strength of high volume flyash concrete.
concrete and the demand far exceeds the supply and makes the construction activities very costlier. Also production of 1tonne of cement releases 1tonne of Co2 thus causing large scale degradation of environment so there is need to conserve the cement. Hence, currently, the entire construction industry is in search of a suitable and effective waste product that would considerably minimize the use of cements and ultimately reduces the construction cost.
The materials which are used for producing the HVFC are as follows
The quantity of fly ash produced from thermal power plants in India is approximately 80 million tons each year, and its percentage utilization is less than 10%. Majority of fly ash produced is of Class F type. The disposal of remaining fly ash has become a serious problem. One of the practical methods for conserving and economizing cement and also to reduce the disposal problem of fly ash is to popularize the |

To get an innovative construction material.
• To effectively use the waste product (Flyash) without any adverse effect on the society. Materials:
Cement: Specific gravity of cement is 3.14. The cement was brought from Priya cements, Salem. Fly ash: Class F fly ash collected from thermal plant mettur with a specific gravity of 2.12 determined as per IS 1727:1967 confirms to (ASTM C 618).
