Quarry dust is a waste obtained during quarrying process. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate.

at 40% of quarry dust and there was an increment of 5.88% at 40% of quarry dust. Jose, et al. (2014) studied the effect of using egg shell powder (ESP) and quarry dust to improve clayey soil. Soil properties were checked by conducting several tests with different mixture proportions of egg shell powder and quarry dust.

Quarry dust is a by-product from the crushing process during quarrying activities. Large scale of cement production causes the discharge of high amount of carbon dioxide resulting in global warming.

added water by the quarry dust. Therefore, they suggested using quarry dust between 55 to 75 %. Furthermore, they suggested for the replacement of sand could be applied by adding of fly ash to replace some cement along with quarry dust or stone dust to replace part of sand in concrete. Suman at all.

Attempts have been made to study the suitability of Quarry dust as sand replacing material and it has been found that Quarry dust improves the mechanical properties of concrete as well as elastic modulus. The optimum compressive strength is achieved at the proportion of fine to coarse with 60:40 ratio.

After adding quarry dust and running several tests, the UCS increases as the proportion of quarry dust increases. When the proportion of quarry dust is increased, MDD increases but OMC declines. There is also a decrease in the swelling of expansive soil. The addition of quarry dust in various quantities reduces L.L, P.L, and P.I [85].

Generally, the quarry waste has a size below 90 microns. Quarry dust is the waste which is hazardous and effects the environment and human health. To eliminate the negative effect of these waste materials, these can be disposed in a proper and safe manner. Also, to ensure a more economically viable disposal, these are blended with …

The main objectives of the experimental investigation are: i. To investigate the potential usage finding the optimum quantity of commercially available fly ash, quarry dust ... in quarry dust content reduces the compressive strength. 3) It was also found that in case of CSEB's using 70% laterite soil, 10% cement and 20% fly ash, the rate of

A large number of dumping locations exist in the vicinity of the quarry areas. Dust emissions from these gigantic dump sites is a major problem due to high wind velocities in this region. So, dumping locations should be provided 500–1000 m away from the residential area or working place. The stone waste can be used to fill empty quarries …

The Pond 1 might be the highest recipient of contaminants (heavy metals) released from quarry activities such as blasting, crushing, and transportation and wind deposition of dust at China quarry ...

Quarry by-products (QB), usually <1/4 in. (6 mm) in size, are the residual deposits from the production of required grades of aggregate. This paper provides findings of a detailed laboratory study with the objective of …

Out of the different quarry wastes, quarry dust is one, which is produced in abundance. About 20–25% of the total production in each crusher unit is left out as the waste material-quarry dust.

quarry dust. The quarry dust is used to manufacturing of hollow blocks. The program involves casting and testing cube specimens in each set consisting of 3 cubes. The cubes were casted using standard cubes of 150 mm × 150 mm × 150 mm. Specific gravity of sand and quarry dust of 2.62 and 2.70. 53 grade cement is used for the mix.

Quarry dust has been proposed as an alternative to river sand that gives additional benefit to concrete. Quarry dust is known to increase the strength of concrete over concrete made with equal quantities of river sand, but it causes a reduction in the workability of concrete. ... The objectives of this study are: To measure the compressive ...

Use of such materials as replacement for conventional building materials can achieve twin objectives of ''waste disposal'' and ''natural resources conservation '' together. This project deals with the experimental study of the characteristic strength of concrete using quarry dust as a complete replacement of river sand fine aggregate tested at ...

Quarry dust satisfies the reason behind the alternative material as a substitute for sand at very low ... compressive strength is quantified for varying percentage and grades of concrete by replacement of sand with quarry dust. OBJECTIVES: The main focus of this study, is the behaviour of concrete that partially replaces sand with quarry dust ...

The quarry dust derived from granite quarry is considered the most suitable for use as a constituent raw material in concrete production due to its highly inert chemical nature.

This study determines the effect of Sulphuric acid on the compressive strength of concrete with Quarry Dust as partial replacement of fine aggregate at 0 %, 15 %, 25 % and 35 %. A total of seventy ...

River sand and lateritic soils were sourced locally around the Landmark University premise with a geographical position of 8.1239° N, 5.0834° E. Red earth soil (Fig. 1) was gotten at a location around a hilly terrain within the University premise while quarry dust (Fig. 2) was obtained from a quarry site within the township of Omuaran at a …

On the effects of dust on vision, only 20% of the participants reported that dust prevents them from seeing things a distance away. Figure 2 shows that most participants reported that the main source of dust in their area was the quarry activity and that the dust movement increased during sunny and dry weather. In addition, they …

3.1 Research objectives . The research objectives are as follows: ... Quarry dust, a by-product from the crushing process during quarrying activities is one of the materials being studied.

The major objectives of the study were as follows:- 1. To determine the significant properties of quarry dust and compare it with the properties of conventional sand. 2. To determine the best suitable ratio of Sand: Quarry Dust in concrete to obtain the ... quarry dust (Mix 3), under thermo shock and high temperature showed the least

sand with quarry dust can be an economic alternative choice. In addition, the use of quarry dust as the complete replacement of natural river sand which acts as the fine aggregate could cut the cost in concrete production. The quarry dust should be used in construction works as the cost of construction would be saved and the natural
