The particle sizes of fine aggregates (sand, laterite, and quarry dust) ranged from 0.06 to 4.75 mm, while coarse aggregate (crushed granite) ranged from 5 to 20 mm in sizes. ...
This article presents the consideration of relation between compressive strength and rebound number of concrete cooperating with quarry dust as fine aggregate (natural river sand was replaced by ...
This work is related to study the compressive strength of concrete using quarry dust as fine aggregate instead of sand and 10mm washed aggregate instead of conventional granite. Three mixes of 1 ...
It is found that 40% replacement of fine aggregate by quarry dust gives maximum result in strength than normal concrete and then decreases from 50%. The compressive strength is quantified for ...
This article presents the consideration of relation between compressive strength and rebound number of concrete cooperating with quarry dust as fine aggregate (natural river sand was replaced by ...
effect of quarry dust and sawdust, by adding 10%,15% and 20% with the fine aggregate, a matured fine aggregate has prepared. Vignesh b, Lingaraju D (Dec ). "Experimental study on partial replacement of quarry dust and saw dust in fine aggregate". In this research was experimentally carried out to investigate properties of both sawdust and ...
The natural river sand, which use in concrete, was partially replaced by quarry dust at the rates of 0% (no quarry dust), 50% and 100 % by weight of fine aggregate.
This paper would be useful in developing mixture of concrete in which quarry dust is used as fine aggregate instead of sand in the future construction projects . Figure 1. Big …
1 QUARRY ROCK DUST AS A PARTIAL REPLACEMENT OF FINE AGGREGATE - STATE OF ART REPORT K.Sai Kumar 1 S.Sameer Kumar2 Dr.M.L.V.Prasad 3 1 & 2 IV-B.Tech, Department of Civil Engineering, BITS, Kurnool ...
The results show that concrete containing quarry wastes as fine aggregate decreased the workability and do not significantly affect the 28-day compressive …
Karthicket al (2014), in his study on the usage of quarry dust as a partial replacement for sand in concrete found that the compressive strength of concrete cubes at 28 days of curing was improved as high as 35.26% above the strength of conventional concrete when 40% of the fine aggregate was replaced with quarry dust by weight.
requisites of fine aggregate as well as it should be available abundantly. 1.2 Properties of Quarry dust: Table 1.2 Properties of Quarry dust Organic material content Nil Compatibility with cement Use any type of Portland cement and blended cements for various mix designs Setting time Normal as preformed by river sand Workability Good
3.5 Quarry Dust: Quarry Dust can be defined as residue, tailing or o ther non-voluble waste material after the extraction and processing of rocks to form fine particles less tha n 4.75 mm. This product can be used for asphalt, substitut e for sand, and filling around pipes. Quarry dust can be an economic alternative to the river sand.
The quarry dust behaves similar to conventional fine aggregate (sand) with respect to aggregate properties and zonal study. The optimum compressive strength is achieved at the proportion of fine ...
the sand replaced with quarry dust, 10% of the cement weight replaced with fly ash, and the same 10% of the cement weight replaced with silica fume by consideration. Without changing the concrete's unit weight or air content, it was discovered that using quarry dust as fine aggregate improved the slump and slump flow of the new concretes.
It was found that quarry dust as fine aggregate enhanced the slump and slump flow of the fresh concretes without affecting the unit weight and air content of the concrete. III LITERATURE REVIEW 2.1 Literature Review Shaviyani Atoll, has reported the condition of sand mining in Maldives where construction is one of the major activities being ...
By replacing fine aggregate with quarry dust in a ratio of 60:40, as done by Hmaid Mir, the compressive strength was maximized. According to Felekoglu et al., adding quarry waste at the same cement content typically results in a reduction in the need for super plasticizer and an increase in the 28-day compressive ...
Durability of controlled flow geopolymer (ranged 110 ± 5% by adding water) mortar which contains fly-ash, sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) as a binder and use quarry dust as fine aggregate were compared to the control conventional cement mortar (W/C=0.4). From the results, the compressive strength of …
Quarry dust fine aggregate decreased the compressive strength due to deficient grading and excessive flakiness. The w/c ratio and slump value increased with the replacement of sand, Voids present in quarry dust mortar were lesser as compared to that of sand hence higher compressive strength. A comparatively good strength is expected when sand ...
This paper explores about utilizing quarry stone dust as a fine aggregate. Abhishek Kumar and Vikram Singh, (2019) Study the Effect of Stone Dust & Steel Fibre on Strength Properties of Concrete.he study The replacements are done at 0%, (30%, 1%), (40%, 1%), (50%, 1%) of fine aggregate with Stone dust and addition of Steel fiber 1% by the ...
2) Fine Aggregate: Fine aggregate of 10mm fine m-sand is used. 3) Coarse Aggregate: Coarse aggregate used in this are size of 15cm. 4) Red Soil: 10 mm fine red soil is been used. V. MIX DESIGN AND SAMPLE PREPARATION The concrete mixture have been made with 100 % replacement of fine aggregate with quary dust and red soil in
Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand. Design mix of M25grade concrete with ...
Quarry rock dust (QRD), a waste obtained during the quarrying process is a significant source of air pollution yet has the potential of becoming a sustainable and …
This waste problem may be avoided as it could be converted into useful application in concrete production. 2.3 Concrete with quarry dust as fine aggregate In a study in Thailand by Khamput [29] on the compressive strength of concrete using quarry dust as fine aggregate and mixing with admixture type E, it was found that with 70% quarry …
Samples of concrete (eg. cylinders, beams) were made using varying contents of lateritic sand and quarry dust as fine aggregate. The proportion of lateritic sand was varied …
Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand. Design mix of M25grade concrete with replacement of 0%, 20%, 25%, 30%, and 35% of quarry dust organized as M1, M2, M3, M4 and M5 respectively have been considered for laboratory …
Replacement of quarry dust with fine aggregate at a ratio of 30 percent produces the best results, but beyond that, the strength obtained gradually diminishes. It has been shown that increasing the proportion of quarry dust in concrete may increase its workability by as much as thirty percent for M40 grade concrete. It has been discovered …
