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.

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.
River Sand Substitutes. Sand Researchers world over are in continuous search for the alternatives to sand. Fine aggregate is one of the important constituents of concrete and mortar in construction industry. River sand is becoming a scarce material. Sand mining .
replacement of cement by flyash. A. Objectives The main objective of the study is 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.
Fly ash is generally used as replacement of cement, as an admixture in concrete, and in manufacturing of ce ... To study the effect of fly ash and egg shell powder ... Use of fly ash and egg shell powder by partially sand replacement in normal concrete for real time projects
Sand: Fine aggregate ... that for 10% to 20% replacement of fly ash with weight of cement compressive strength is increases ... This research concludes the study of the effect of fly ash on the properties of concrete‖ for nominal mix of M25 grade of concrete are as follows. 1. Slump loss of concrete increases with increase in w/c ratio of ...
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
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.
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 ...
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 % Rice Husk Ash + % Fly Ash with 60% of
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.
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 .
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).
