KEYWORDS: Concrete, Natural sand, Alternative materials, Quarry dust, Foundry sand, Mechanical properties. I. I.INTRODUCTION Concrete is that pourable mix of cement, water, sand, and gravel that hardens into a super-strong building material. Aggregates are the important constituents in the concrete composite that help in
Various researchers are developing efforts to integrate waste and by-products as alternative materials in road construction and maintenance, reducing environmental impacts and promoting a circular economy. Among the alternative materials that several authors have studied regarding their use as partial or total substitutes for natural aggregates in the asphalt paving …
alternative material to natural sand. Some alternatives materials have already been used as a replacement of natural sand such as fly-ash, quarry dust or limestone and siliceous stone powder, filtered sand, copper slag are used in concrete and mortar mixtures as a partial or full replacement of natural sand (Chandana Sukesh et al 2013)[9].
We can provide CE Declaration of Conformity and Marking Certificates for all of our sand, gravel, clay, soil, decorative stone and aggregate products We actively encourage the general public, smaller builders, landscapers and DIY …
Instead of natural sand, use fly ash, quarry or limestone powder, silica stone powder, filtered sand and copper slag to partially or completely replace the natural sand in the cement and mortar …
The investigations on the durability of concrete made with natural granular granite, silica sand and powders of waste marble and basalt as a fine aggregate were reported in . It was observed that, a better condensed matrix which can yield a perfect, less permeable concrete by incorporating appropriate fine aggregate type and ratio.
Here the natural sand is replaced partly here by quarry dust (QD) and sawdust (SD) with different percentages i.e. is 50% of natural sand as constant and remaining 50% as the different proportions of Quarry dust and Saw dust. respectively by weight and effects of replacement on concrete is observed.
Many researchers are finding different materials to replace sand and one of the major materials is quarry stone dust. Using different proportion of these quarry dust along with sand the required concrete mix can be obtained. This paper presents a review of the different alternatives to …

In this present experimental study on concrete having grades of M25 are prepared by replacing natural sand by Quarry dust and Marble powder. The main cause of concern is the non …
The overuse level of cement and natural sand for civil industry has several undesirable social and ecological consequences. As an answer for this, industrial wastes called as by-products (pozzolanic materials) such as fly ash, GGBFS, silica fume and metakaolin can be used to interchange partially cement and natural sand by manufacturing sand (M-sand). In this …
Therefore, need to use this. The quarry dust is use in the concrete and the properties are studied experimentally and presented in this paper. Concrete is prepared with the process of replacing sand which isnatural/of river by dust produced from quarry of rock with the percent proportions which varied from 0%, 25%, 50% and75%.
Researcher and Engineers have come out with their own ideas to decrease or fully replace the use of river sand and use recent innovations such as M-Sand (manufactured sand), robot …
This document presents an experimental study on self-compacting and self-curing concrete using quarry dust to replace natural sand, light weight aggregate, and silica fume. Tests were conducted on concrete cubes to evaluate the compressive strength at …
demand of natural sand by using quarry waste to replace the use of natural sand. We are investigating the potential of using ... silica, alumina and iron oxide. When mixed with water, Portland cement undergoes hydration-a ... Mix ratio of 1:1.5:3 (cement: aggregate: sand+ quarry dust) give the optimum strength in this study. (refer Table 6,7) 2 ...
At Mainland Aggregates, we supply an extensive collection of aggregates, some of our best-selling quarried aggregates include 20mm gravel and 10mm gravel. In addition to our most popular products, we can also supply MOT Type 1, MOT Type 3, rail track ballast, building sand, premium silica sand and much more.
Quarry dust 2.67 Natural coarse aggregate 2.702 Manufactured sand belongs to Zone II, waste foundry sand belongs to Zone III and quarry dust belongs to Zone IV fine aggregate. 3. PREPARATION OF SPECIMENS Five different concrete mixes were prepared by varying the proportions of the three constituent fine aggregates namely, manufactured sand (MS ...
The river deposits are the most common source of fine aggregate. Now-a-days the natural river sand has become scarce and very costly. ... Foundry sand is high quality silica sand with uniform physical characteristics. ... Dr. P. Perumal (12, December, 2013) -Use of Quarry to Replace Sand in Concrete – An experimental... J. Karthick, T.Rama ...
Construction aggregates derived from primary resources either by crushing of sound rock masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments (natural sand and gravel aggregates) make the most voluminous mineral raw material exploited by humans nowadays (Fookes 1991; Přikryl 2017).Extremely low per-unit cost of the …
In this study, the effect of colloidal nano-silica replacing a fraction of cement and recycled concrete fine aggregate replacing natural sand on the post-fire mechanical features and durability of concrete was explored. To achieve this goal, 189 concrete samples were manufactured in total, with key variables being the volume of fine aggregate at 0, 50, and …
