replacement.The presence of foundry sand and mineral admixtures increasing the compressive strength and also withstanding the maximum load. Compare to fly ash GGBS attains good strength as cement replacement. Mr. Sabale Vishal Dhondiram et al (2009), "Experimental Study on High Performance .
It is also very important to study the effect of this partial replacement of sand on concrete, to find the optimum replacement of fine aggregate. Therefore the study of properties of concrete with different proportion of replacement of sand by pond ash is covered in this project work.
The modulus of elasticity of concrete increases upto 60% replacement of sand with flyash and it decreases beyond 60%. It is economical, and eco-friendly. The replacement of sand with fly ash upto 50% is beneficial for the concrete works. This study could enlighten the local people to use fly ash to replace sand for concrete works.

Experimental study of concrete made with granite and iron powders as partial replacement of sand. Author links open overlay panel Shehdeh Ghannam a Husam Najm b Rosa Vasconez c. Show more. ... the fly ash-based geopolymer provided better resistance against aggressive environment and elevated temperature compared to normal concrete.
with a replacement of fine aggregate by fly ash up to 20% and then decreasing for both the mixes. Corresponding variation in density was also observed (Fig 3). Whereas water absorption was found increasing on higher percentage of fly ash replacement owing to the higher surface area of fly ash particles compared with sand (Fig. 2).
replacement of natural sand by fly ash is about 30% as compared to reference mix (0% replacement). 3. It is observed that the residual tensile strength of concrete when subjected to elevated temperature of 200°C for 4 hours, is higher at 40% replacement of natural sand by fly ash. After 40% replacement the tensile strength decreases.
m ethods used in present study for replacing sand with fly ash are the oldest and basic conceptual methods and will provide a simple but effective way of replacing sand with fly ash at site. Wang et al. [2] used recycled mineral admixture such as fly ash, slag, glass sand and rubber powder as re-
The study presented in this paper shows that fly ash can partially replace sand in cement concretes. This type of fly ash concrete has a lower density and manufacturing cost, a reduced coarse ...
Experimental Study on Partial Replacement of Cement by Flyash and GGBS Syed Asif Ali1 Professor Shaik Abdullah2 1P.G Student (Structural Engineering) 2Professor 1,2Department of Civil Engineering 1,2K.B.N Engineering College, Gulbarga, Karnataka, India Abstract— This paper presents a .
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.
This study attempts the comprehensive understanding of the influence of mix proportioning on the strength development in mortars with partial replacement of cement with fly ash and partial replacement of fine aggregate (sand) with fly ash. Materials and Methods Mortar compositions ...

divided produced by coal-fired power station. Fly ash possesses pozzolonic properties similar to naturally occurring pozzolonic material. The detailed experimental investigation is doing to study the effect of partial replacement of cement by FA, RHA with using Steel fiber in concrete.
replacement of cement by flyash. A. Objectives The main objective of the study is 1.To make a concrete with percentage replacement of cement by GGBS and FLYASH. 2. To compare the compressive strength and flexural strength of replacement concrete with normal concrete. II. MATERIALS USED AND PROCEDURE 1. Fly ash 2.
The most widely used specification for fly ash in North America is ASTM C618 Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete (AASHTO M 295). This specification divides fly ash into two classes based on its source of .
