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.
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.

Sep 30, 2017· Characteristic study of geopolymer fly ash sand as a replacement to natural river sand. ... Presently crushed sand or high volume fly ash are used as natural sand replacement, however geoploymer fly ash sand could be better environment friendly replacement. In this research geopolymer fly ash sand (GFS) particles are prepared by geopolymerising ...
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-
Sep 18, 2015· This paper presents a laboratory investigation on optimum level of Fly ash and Ground Granulated Blast Furnace Slag (GGBS) as a partial replacement of cement to study the strength characteristics of concrete.

Abstract. The experimental work is carried out to investigate the optimum percentage of flyash and silicafume to replace cement effectively. An attempt is made to replace cement with flyash from 0 to 100 % with an interval of 10 % for minimum grade concrete i.e., M20 and is tested for fresh and hardened properties to identify the optimum percentage of flyash in concrete, on the other hand for ...

This paper presents a laboratory investigation on optimum level of Fly ash and Ground Granulated Blast Furnace Slag (GGBS) as a partial replacement of cement to study the strength characteristics of concrete. Portland cement was partially replaced by
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.
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 ...
The detailed study is on the effect of partial replacement of cement with Rice Husk Ash and Fly Ash on concrete. In this project different combination of Fly Ash and Rice Husk Ash as a partial replacement of cement and river sand by quarry sand is carried out. The composition of 7.5% Rice Husk Ash + 22.5% Fly Ash with 60% of
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).
Experimental Study on Partial Replacement of Natural Sand ... additions of limestone filler or fly ash – taken separately or altogether, determine a decrease of the setting time ... 2.1.4 Manufactured sand : M-Sand is replaced is fully replacement of river sand .
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 .
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.
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.
demand of natural sand by using quarry waste to replace the use of natural sand. We are investigating the potential of using quarry waste and its effect on the strength and workability of concrete. This paper reports the experimental study which investigated the partial replacement of sand with quarry dust.
