This study shows the comparative analysis engineering, the physical and mechanical properties of river sand concrete with quarry dust concrete. The selected materials were batched by weight and volume. The water-cement ratio opted as 0.50 1:2:4 for mix ratio was selected for the experimental investigation respectively. The specimens were cured for 7, 14, 21, and 28 days. For the purpose Slump, density, and compressive strength tests were carried out. The river sand concrete showed better results and greater density and compressive strength than quarry dust concrete for all curing ages. The 28 days of curing, river sand concrete rise the required compressive strength by 36%, whereas quarry dust concrete was less than the limit compressive strength by 12%. Both river sand concrete and quarry dust concrete for the selected water/cement ratio and mix ratio has been found suitable for non-structural applications and lightly-loaded members where high strength is not a prerequisite. Keywords: River Sand; Quarry Dust; Density; Compressive Strength; Concrete

At the East of Thailand, a shortage of river sand for producing concrete has frequently occurred while the large amounts of quarry dusts are being produced as by-products of stone crushers in many stone quarries. Then, the quarry waste from 12 stone quarries (in Rayong and Chonburi province) was taken to investigate the engineering properties as fine aggregate for concrete. The properties - namely type of parent rock, specific gravity, water absorption, gradation, fineness modulus (F.M.), organic impurities level, powder content, plastic index and sand equivalent value - were examined. The results show that the parent rocks of the samples are limestone, granite and rhyolite. The specific gravity of samples were in the range of 2.61 - 2.77. The gap gradations are found in all samples and the F.M. values slightly exceed the limit of ASTM standard. Absorption of quarry dust is high (around 2 %). Although the high powder contents are found in all samples, the powder in quarry waste is non-plastic and non-organic material. Therefore, gradation and absorption of quarry waste could be carefully considered or improved before using quarry waste as fine aggregate in concrete.


Waterway sand and pit sand are the most normally utilized fine aggregates for concrete creation in many parts of the world. Huge scale extraction of these materials presents genuine ecological risk in numerous parts of the nation. Aside from the ecological danger, there still exists the issue of intense lack in many regions. In this way, substitute material in place of river sand for concrete production should be considered. The paper means to examine the compressive and split tensile qualities of concrete produced using quarry residue, sand, and a blend of sand and quarry dust. The experimentation is absolutely research facility based. A total of 60 concrete cubes of size 150 mm x 150 mm x 150 mm, and 60 cylinders 150 mm in diameter and 300 mm deep, conforming to M50 grade were casted. All the samples were cured and tested with a steady water/concrete proportion of 0.31. Out of the 60 blocks cast, 20 each were made out of natural river sand, quarry dust and an equivalent blend of sand and quarry dust. It was discovered that the compressive strength and split tensile strength of concrete produced using the blend of quarry residue and sand was higher than the compressive qualities of concrete produced using 100% sand and 100% quarry dust.

This work focuses on the 100% replacement of river sand with quarry dust in the production of concrete. Two types of concrete were produced (concrete made with river sand and that made with quarry dust as fine aggregate), the concretes produces were cast into beams and cured for 28 days. The flexural strengths of the concrete beams cast was determine at 28 day strength. At 28 days target strength the maximum flexural strength of concrete made with river sand as fine aggregate is 5.375111N/mm2 and minimum flexural strength is 2.2155N/mm2, for the concrete made with quarry dust as fine aggregate the maximum flexural strength is 2.567 N/mm2. The maximum value of 2.567 N/mm2 for concrete made with quarry dust as fine aggregate is higher than the minimum value of 2.2155N/mm2 for concrete made with river sand as fine aggregate. With this result it shows that quarry dust is a good substitute to river sand in the production of concrete.

The numerous demanding application of concrete is not readily met with Ordinary Portland Cement (OPC) alone. To meet up the demand and as well as ensured the green concrete durability, it has becomes necessary to incorporate mineral additions with the best combination of others by-product as replacement to improve the performance without jeopardizing the strength of the concrete. In the construction industry, OPC cement and river sand are used as important building material making it scarce and limited. Whereas, as for the cement is well known as the biggest culprits for emitting carbon dioxide (CO2). Hence, partial replacement of cement becomes a necessity as well as natural sand in concrete by waste material or by-product without compromising the quality of the end product. Partial replacement with Ground Granulated Blast furnace Slag (GGBS), Fly Ash (PFA), Silica Fumes (SILICA) incorporates with 100% of Quarry Dust (QD) as sand replacement. The usage of 100% QD with OPC+PFA+SILICA (Mix 2) produced more durable concrete with good temperature control and better furnishing than with 100% river. In addition to the cost effect benefit, the reduction in depletion of river sand, addressing environment and sustainability issues, it is a valuable contribution in creating a green concrete.

As a Quaternary repository of wind-reworked Indus River sand at the entry point in the Himalayan foreland basin, the Thal Desert in northern Pakistan stores mineralogical information useful to trace erosion patterns across the western Himalayan syntaxis and the adjacent orogenic segments that fed detritus into the Indus delta and huge deep-sea fan throughout the Neogene. Provenance analysis of Thal Desert sand was carried out by applying optical and semi-automated Raman spectroscopy on heavy-mineral suites of four eolian and 11 fluvial sand samples collected in selected tributaries draining one specific tectonic domain each in the upper Indus catchment. In each sample, the different types of amphibole, garnet, epidote and pyroxene grains—the four dominant heavy-mineral species in orogenic sediment worldwide—were characterized by SEM-EDS spectroscopy. The chemical composition of 4249 grains was thus determined. Heavy-mineral concentration, the relative proportion of heavy-mineral species, and their minerochemical fingerprints indicate that the Kohistan arc has played the principal role as a source, especially of pyroxene and epidote. Within the western Himalayan syntaxis undergoing rapid exhumation, the Southern Karakorum belt drained by the Hispar River and the Nanga Parbat massif were revealed as important sources of garnet, amphibole, and possibly epidote. Sediment supply from the Greater Himalaya, Lesser Himalaya, and Subhimalaya is dominant only for Punjab tributaries that join the Indus River downstream and do not contribute sand to the Thal Desert. The detailed compositional fingerprint of Thal Desert sand, if contrasted with that of lower course tributaries exclusively draining the Himalaya, provides a semi-actualistic key to be used, in conjunction with complementary provenance datasets and geological information, to reconstruct changes in paleodrainage and unravel the relationship between climatic and tectonic forces that controlled the erosional evolution of the western Himalayan-Karakorum orogen in space and time.

The increase in the demand for concrete production for the development of infrastructures in developing countries like Ethiopia leads to the depletion of virgin aggregates and high cement demand, which imposes negative environmental impacts. In sustainable development, there is a need for construction materials to focus on the economy, efficient energy utilization, and environmental protections. One of the strategies in green concrete production is the use of locally available construction materials. Scoria is widely available around the central towns of Ethiopia, especially around the rift valley regions where huge construction activities are taking place. The aim of this paper is therefore to analyze the suitability of scoria as a fine aggregate for concrete production and its effect on the properties of concrete. A differing ratio of scoria was considered as a partial replacement of fine aggregate with river sand after analyzing its engineering properties, and its effect on the mechanical properties of concrete were examined. The test results on the engineering properties of scoria revealed that the material is suitable to be used as a fine aggregate in concrete production. The replacement of scoria with river sand also enhanced the mechanical strength of the concrete. Generally, the findings of the experimental study showed that scoria could replace river sand by up to 50% for conventional concrete production.


In recent decades, there is a sprut in the growth of the construction industry. Aggregates are one of the main ingredients for making concrete. Depletion of natural resources of sand and the effect of mass production of cement on sustainable environment, need studies on the use of alternative materials. On the other hand, dumping of wastes from the industries are piling up resulting in the pollution of the environment. By considering the above facts, severe studies are focused on partial replacement of river sand with alternatives like copper slag, steel slag, quarry dust, etc., The outcome of these studies shows that the alternate materials enlarge the mechanical and durability properties of concrete. The optimum dose of alternate materials to replacement of sand is evaluated. In this paper, technical papers published by researchers are studied, discussed and compared

The use of crushed quarry dust as a partial replacement of river sand in concrete production was investigated in this study. This is expedient as quarry dust can be available at some locations with insufficient river sand for construction purposes. The use of quarry dust is also in concrete is also a measure necessary for improvement of concrete strength. River sand was replaced with quarry dust for different mix designs of concrete for 0% to 25% replacement levels with 5% intervals. The physical properties of river sand and quarry dust were tested and reported and the workability as well as compressive strengths of the concrete mixtures were also tested. It was observed that the slump values increased with increase in percentage replacement of sand with quarry dust. The compressive strength of cubes at 28 day curing for control mixture of 1:3:6 at 0% partial replacement of river sand with quarry dust was 12.6N/mm2 but compressive strengths of 21.5 N/mm2 and 26.0 N/mm2 were gotten for 1:2:4 concrete and 1:1.5:3 concrete respectively. As the quarry dust content increased to 25%, the 28day compressive strength increased to 13.58 N/mm2 and 21.57 N/mm2 for the 1:3:6 and 1:2:4 mixes respectively. Compressive strength values decreased to a value of 25.72N/mm2 for the 1:1.5:3 concrete mix. The maximum compressive strength values were reached at 20% quarry dust content at the age of 28 days for the three concrete grades investigated. The increase in compressive strength with inclusion of quarry dust was attributed to the higher specific gravity of quarry dust above river sand. The compressive strength of quarry dust concrete continued to increase with age for all the percentages of quarry dust contents. Quarry dust was recommended as a suitable partial replacement for river bed sand in concrete production.
