Gradation: ASTM D1073 defines a fine aggregate in asphalt paving mixtures as an aggregate that passes the 9.5 mm (3/8 inch) sieve. (14) Boiler slag, with few exceptions, meets this size requirement and most bottom ash sources, with minimal screening of oversize material, will satisfy this definition of a fine aggregate. Bottom ash is predominantly sand-sized, usually with 50 to 90 percent ...
Mar 24, 2014· study on concrete containing bottom ash as partial replacement of fine aggregate project done by S.Mohana sundari.
This research focuses on evaluating the feasibility of utilizing bottom ash from coal burning power plants as a fine aggregate in cellular concrete with various contents. Flows of all mixtures were controlled within 45 ± 5% and used content at 30%, 40%, 50%, 60%, and 70% by volume of mixture. Bottom ash from Mae Moh power plant in Thailand was used to replace river sand at the rates ...
Use of Unprocessed Coal Bottom Ash as Partial Fine Aggregate Replacement in Concrete 68 2.2 MATERIAL PROPERTIES 2.2.1 Particle size distribution Table 3: Sieve analysis of Fine aggregate and Bottom ash Aggregate Type BS sieve size (mm) Fine Bottom ash % Retained Cumulative % passing % Retained Cumulative % passing 4.750 0.09 99.91 0 100
containing bottom ash as a partial replacement of fine aggregates, after which it decreased. A high strength concrete was developed by using Alccofine as a partial replacement to cement along with the partial replacement of fine aggregates with bottom ash. Keywords — Fine aggregates, coal bottom ash,
In this study, the effect of the nonground bottom ash (BA), as fine aggregate in mortar or concrete, on shrinkage cracking is observed on mortar specimens. The replacement was made by weight; the replacement ratios for BA as fine aggregate were 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and .
In order to effectively use the bottom ash discharged from coal-fired thermal power stations, concrete which substitutes bottom ash from 0 to 40 percent in volume for fine aggregate was investigated in this study. The compressive strength, tensile strength, freezing and thawing resistance, and abrasion resistance of the concrete were examined.
bottom ash make it attractive to be used as fine aggregate in the production of concrete. Singh and Siddique [1] also reported that coal bottom ash is the potentially viable material to be used as fine aggregate in the production of concrete. The previous studies in which coal bottom ash has been targeted as a substitute for
percentage as fine aggregate substitute in cement concrete. During the combustion of pulverized coal at the thermal power station the product formed are bottom ash, fly ash and vapours. There bottom ash is that part of residue which is fused into particles and is collected
The specimens with bottom ash as replacement with fine aggregate was found to be better in compression which has compressive strength of 14.02% and 15.05% more than that of nominal mix concrete after 7 days and 28 days curing period respectively for 10% Bottom ash + 90% Fine aggregate.
bottom ash as fine aggregate single or mutually leads to sufficient durability properties (Bilir, 2012). Even though the strength development is less for bottom ash concrete, it can be compared to low grade of normal concrete. Concrete containing 50% of bottom ash as fine aggregate gave compressive strength more than 20 Mpa at 28 days is
Bottom ash and boiler slag are considered fine aggregates in this use. To meet required specifications, the bottom ash or slag may need to be blended with other natural aggregates prior to its use as a base or subbase material.

Replacement of Fine Aggregate with Bottom Ash in Concrete and Investigation on Compressive Strength - written by Dr. R. G. D'Souza published on 2017/08/10 download .
fine aggregate. Keyword: Bottom ash, Cement, Coarse aggregate, concrete, sands, strengths. 1. Introduction 1 India produces approximately more than 100 million tonnes of Coal ash annually. Coal-based thermal power plants all over the world facing serious problems of handling and disposal of the ash produced.The utilization ...
This study evaluates the strength and durability properties of concrete incorporating low-calcium coal bottom ash as partial or total replacement of fine aggregate. The test results indicate that at a fixed water-cement ratio (w/c), workability, 28-day compressive strength, splitting tensile strength, and pulse velocity through concrete ...
Experimental Investigation on Replacement of Fine Aggregate with Bottom Ash in Concrete Govindarajan D1, Keerthana M2*, Kumara raja G3, Prasanna Kumar R4 1,2,3,4School of Civil Engineering, SASTRA University, Thanjavur-613401,India. *Corres.author: keerthana_1505@yahoo,
of fine aggregate replaced bottom ash concrete continues to aggrandize with age for all the bottom ash contents. Mix containing 30% and 40% bottom ash, at 90 days, attains the compressive strength equivalent to 108% and 105% of compressive strength of normal concrete at 28 days. The span required to attain the required strength is
(14) Boiler slag typically meets maximum size requirement for fine aggregate, while bottom ash sources may require minimal screening of oversize material to satisfy the definition of a fine aggregate. Because boiler slag is typically poorly-graded, blending with other aggregates .
Bottom ash was classified as Class C ash. The porous structure, angular and rough texture of bottom ash affected its specific gravity and particle density. From the tests, it was found that bottom ash is recommended to be used in concrete as a replacement for fine aggregates.
Jun 21, 2013· The objective of this research was to examine the technical feasibility of upgraded bottom ash from municipal solid waste incinerators as fine and coarse aggregate in .
This work deals with the Bottom ash as a replacement of fine aggregates in concrete and the investigation on the use of bottom ash has been very limited. It gives an overview of the various literature and experimental investigations been carried out by many researchers to study the use of bottom ash as aggregates in concrete.
