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

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.
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.
(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 .
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 .
Bottom ash can be used as a replacement for aggregate and is usually sufficiently well-graded in size to avoid the need for blending with other fine aggregates to meet gradation requirements. The porous surface structure of bottom ash particles make this material less durable than conventional aggregates and better suited for use in base course ...
of Incinerator bottom ash aggregates mortar by adding the two admixtures. The study shows that, based on the 1:2 cement/aggregate weight ratio, Incinerator bottom ash fine aggre-gates mortar, unit weight around 1.8 g/cm3, is 20% lighter natural fine aggregate mortar, unit weight around 2.2 g/cm3. The Incinerator bottom ash fine aggregates ...
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 .

Coal-based thermal power plants all over the world facing serious problems of handling and disposal of the ash produced.The utilization ...
Zn and Ni of Bottom Ash as a Potential Diffuse Pollutant and their Application as "Fine Aggregate" Hasan Md Anamul *, Jenifer Rahman, Mufrad Tanvir. Department of Civil and Environmental Engineering (CEE) S. hahjalal University of Science and Technology, Sylhet, 3114, Bangladesh . Abstract
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 .
Mar 24, 2014· study on concrete containing bottom ash as partial replacement of fine aggregate project done by S.Mohana sundari.
Kim and Lee (2011) demonstrated that the flexural strength of concrete decreased linearly as the replacement ratio of fine and coarse bottom ash was increased. The modulus of rupture decreased by 19.5% and 24.0% on replacement of normal aggregates with fine and coarse bottom ash .
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
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
Durability of concrete incorporating non-ground blast furnace slag and bottom ash as fine aggregate. ... The paper presents investigation of how the usage of bottom ash (BA), granulated blast furnace slag (GBFS), and combination of both of these materials as fine aggregate in concrete affects the concrete durability. ... used as fine aggregate ...
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.

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.

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
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.

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 ...
