Sand is often utilized as a fine aggregate in concrete, contributing 22 to 62% of the total mass. The quantity and features of sand in concrete have an impact on its workability, mechanical characteristics, and durability. Effective replacements are needed as natural silica sand becomes scarcer. By incorporating these by-products into concrete, landfill discharge …
In general, the percentage increase in the compressive strength of SW-SS concrete is reported to be as high as 75% after 7 days and less than 10% after 180 days [53]. …
2.1 Physical Properties of Coarse Aggregates 2.1.1 Gradation. Particle size distribution of aggregates significantly affect the packing density and void content in concrete. According to Neville [], the gradation of aggregate has the main role in establishing the workability of mixtures.Gradation can influence workability, segregation, bleeding, pumpability and …
This paper explores the feasibility of using recycled fine aggregate in concrete to meet strength requirements for various applications in sustainable construction. The physical and mechanical characteristics including: aggregate strength, gradation, absorption, specific gravity, shape and texture, play crucial roles in determining concrete strength. The quality of recycled …

Fine Aggregates This experiment employed locally sourced fine aggregate. Through an IS sieve, the aggregate was screened. Sand or fine aggregate could be crushed or natural. It might be found in a quarry or a riverbank. Sand particles range in size from a maximum of 4.75 mm down to 150 microns, or 0.150 mm. All of
The aggregates passing 4.75 mm tyler sieve and retained on .075 mm sieve are classified as Fine Aggregate. Types of Fine Aggregate. Usually, sand, crushed stone, and crushed bricks are used as fine aggregate in concrete or pavement construction. Sand. Sand is an important engineering material. In concrete works, sand is used as a fine aggregate ...
The angular shape and rough surface texture of fRCA particles could lead to improved strength of concrete due to better interlocking between particles as reported for high-strength concrete with crushed fine aggregates [134]. However, strength depends not only on properties of aggregates but also on the volume of the paste [94].
Sand beach has been widely used at the archipelago as fine aggregate in concrete mixture. Sand beach's is available in huge quantities in many country side but the quality still needs to be ...
strength of concrete is checked. 36 samples were tested. For different tests such as compressive strength, split tensile strength, flexural strength on different shaped samples (cube, cylinder, & beam). Each 9 samples casted with different fine aggregates found in the river Jehlum at different locations namely, Qamarwari, Pampore, and Lasjan.
Along with determining a sulphur concrete mix, sulphur concrete with different fine aggregate like beach sand, eco sand and manufactured sand replacing river sand in 0%, 25%, 50%, 75% and is also studied. Durability of sulphur concrete of each type fine aggregate with best compressive strength is also studied.
Discover the types and classification of fine aggregate used in concrete mix design and its role in producing a strong and durable final product. ... sea sand . Specific applications of fine aggregate. ... robust, chemically …
Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd sieve and 3 rd sieve. It means the average aggregate size is in between 0.3mm to 0.6mm as shown in below figure.
This paper presents the results of a study that investigated the properties of concrete made with dune sand. Different control concrete mixtures using ordinary Portland cement (OPC) with a minimum design compressive strength of 40 N/mm 2 were prepared. The amount of fine aggregates constituted about 36% by weight of all the aggregates.
Concrete sand serves as a staple in the creation of cement-based mixtures due to its coarse texture which enhances the strength and durability of the finished product.. Its unique characteristics facilitate optimal binding of concrete components, contributing to the structural integrity of buildings and infrastructure.
aspects of aggregates in concreting are: (a) strength and durability, (b) free of organic impurities, (c) low alkali reactivity with cement, and (d) proper gradation ... applications like road pavement and concrete. 150 10 Sand: The Fine Aggregate. 10.4 Aggregates for Constructions Different types of aggregates such as sand, gravel, and crushed ...
The mechanical characteristics of geopolymer concrete made with sea sand as the fine aggregate were researched by Khoa et al. [150]. The geopolymer concrete reached a …
As per several studies, the replacement of coarse aggregate with fine sand in concrete reduces the strength by 25 to 30%. In some instances, it can decrease to two to three times the strength of conventional concrete. In general, the …
We would like to show you a description here but the site won't allow us.
strength of the concrete in which sea sand was used as fine aggregate is partially or completely replaced. For this study first control specimens were laid for M20 grade concrete. …
The lack of river sand has led to the use of sea-sand and crushed stone fines in many countries, with the use of sea-sand in the UK being an example [4]. More than 90% of …
Sea sand is a material used as a substitute for ordinary sand for a mixture of cement, fine or coarse aggregate and water, with the mixture when poured into a mold and then allowed to stand hard.

WFS is an excellent fine aggregate for concrete. • With substitution of 30%, the strength of fine aggregate replaced with WFS peaks and then gradually declines after 28 days, and with 30% replacement of sand offered maximum strength. (Ankush et al., 2017) 17: India: Replacement level was 10%, 20% and 30 % for both ferrous and nonferrous WFS •
Micro-Deval Test. Is an abrasion loss test carried out on fine or coarse aggregate samples that are partially submerged in water. The Micro-Deval Apparatus is essentially a ball mill using stainless steel jars positioned on a roller mechanism. Samples, with water and an abrasive charge of steel balls, are placed in the jars and then rotated for a prescribed time at a specified speed.
