The present experimental program is aimed for optimal values of compressive strength flexural strength and split tensile strength of Geopolymer concrete by varying the fly ash content and also
The mixed slag fine aggregate MSFA was used to replace 0 25% 50% 75% and 100% of the natural fine aggregate volume Although existing literature reports that the chloride ion
The reduction in workability of RAC is mainly attributed to the porous AM and ACP which leads to an increase in water demand of fresh concrete Kisku et al 2017;Verian et al 2018
Investigating combinations of 100% recycled coarse and fine concrete aggregates provides a viable solution for repurposing concrete waste generated from demolition renovation and construction activities diverting it from landfills and promoting a circular economy approach The recycled aggregate was used as a 100% replacement by volume
size of coarse aggregat e is needed a great er volume of fine aggregate to protect particles a nd maintain the cohesivenes s of the mixture of concrete Berw al & Goel 2017
Nowadays utilization of RFA as a replacement to fine aggregates in concrete is being popularised Major sources for RFA are concrete bricks glass bitumen from the construction industry Researchers have reported that RFA tends to require more water and superplasticizer than river sand to obtain workability due to the presence of dust and

Ettuet al [17] after conducting compressive strength tests on a total of 120 standard 150 mm concrete cubes concluded that laterite could be used as the sole fine aggregate in structural
• Very fine material such as silt clay or dust of fracture can increase the water demand in concrete • Fines limit is 3% in ASTM C 33 for concrete subject to abrasion • Manufactured sands 5% and 7% • Coarse aggregate limit is 1% % for crushed stone 32 Gradation & Fineness Modulus Dry Sample Wt g Sample Retained Sieve Size
On the shrinkage of concrete the fine aggregate properties also have a significant impact Types Of Fine Aggregate uses In concrete or pavement construction usually sand crushed stone and crushed bricks are used as fine aggregates as given below; Sand Sand is used as a fine aggregate in concrete work and is an important engineering material
Crumb rubber <5 mm grinded from waste tyres was introduced to substitute for natural fine aggregate in concrete and effectively solves the consumption challenge This paper reviews the performance of concrete with crumb rubber as fine aggregate providing evidence for crumb rubber concrete CRC materials design and application
The role of aggregate in concrete is often overlooked hidden in the shadows of more apparent elements like cement and steel Yet in reality it serves as the bedrock of the concrete mix influencing the durability strength and even the aesthetic appeal of our From our towering skyscrapers to the very pavement beneath our feet aggregates play a
