with quarry dust without the inclusion of fly ash resulted in a reduction in the compressive strength of concrete paving block specimen. It has also been reported that the reduction in the compressive strength of quarry dust concrete was compensated by the inclusion of fly ash into the concrete mix. Rao et al., (2011) reported an
investigation SCC was made with partially replacing fine aggregate with quarry dust and cement with fly ash. Six mixes with different percentages of quarry dust (0%, 10%, 20%, 30%, 40%and 50%) as ...
materials in concrete. Fly ash has been used for the past several decades in the manufacture of concrete. But the use of fly ash in Nano form into the concrete is yet to gain popularity through much research is being done in this direction, 1) Total production of flyash in the world. 2) Total production of flyash in India. 3) The uses of flyash.
characteristics of Quarry Dust Concrete (QDC) containing 0% to 30% of fly ash. Based on the test results, it can be concluded that combined use of quarry dust and fly ash can be shown improved strength in concrete and also preserve the environment. Keywords: - Fly Ash, Properties, Quarry Dust, Strength I. INTRODUCTION

Hence the use of Bamboo and quarry dust as replacement for coarse aggregate and fine aggregate in concrete is reducing the Environmental wastes which pose a difficult problem in its disposal. View ...
According to Naganathan et al., [17], quarry dust has discussed the use of quarry dust as a sand replacement. been used successfully in concrete, pavement material for concrete production which showed a. construction and in controlled low-strength materials maximum increase in compressive strength (19.18%), (CLSM).
Therefore, water to cement ratio was increased for concrete with quarry dust to sustain similar workability of conventional concrete [31,32]. On the other hand, the presence of quarry dust improved the mechanical characteristics and durability aspects of the concrete [29,33]. ... It would be beneficial to use fly ash and quarry refuse for ...
The effects of metakaolin in fly ash based self-compacting concrete on the flexural strength are shown in Table 6. The maximum flexural strength is 6.2 N/mm 2 for 15% replacement of metakaolin. The effects of metakaolin and quarry dust in fly ash based self-compacting concrete on the flexural strength are shown in Table 6 and Fig. 3.
This study aims to assess the production of cellular micro-concrete, consisting of quarry dust, calcareous fly ash, cement, and aluminum powder as aerating agent. The proposed mixture design methodology is based on a Box–Behnken fractional factorial experimental design. Testing of specimens included compressive and flexural …
This paper investigates the possibility of using waste materials such as quarry dust and fly ash in the manufacture of cold-bonded aggregates. The artificial …
Sigrun Bremseth [2] focused on the use of ASTM Class F fly ash in concrete, as a part of blended cement or used directly into concrete mixer. There were many articles that highlight the good properties of the use of fly ash, but few with the connection between fly ash blended cement and fly ash blended concrete and field construction. The study
6) Quarry Dust(QD) Locally available quarry dust was collected from crushing quarry near Mailam. Quarry dust comprises of the smaller aggregate particles, so it was sieved to 1.18mm and then used for the replacement of fine aggregate. Table-6: Properties of Fly Ash Physical Properties Test Results Colour Grey Specific Gravity 2.4
laterite soil, cement and fly ash / quarry dust. This investigation is done to know whether the partial replacement of conventional cement stabilization in combination with fly ash and quarry dust brings about enhanced properties. The preparation of CSEB's is done in the following sequential process. 1.775 1.7 1.65 B.
The compressive strength of concrete with 0%fly ash, 50%quarry dust alone is about 150.16% of conventional concrete. The compressive strength of concrete with 10%fly ash, 50%quarry dust alone is about 163.30% of conventional concrete. The compressive strength of concrete with 20%fly ash, 50%quarry dust alone is about …
Partial replacement with Ground Granulated Blast furnace Slag (GGBS), Fly Ash (PFA), Silica Fumes (SILICA) incorporates with of Quarry Dust (QD) as sand replacement. The usage of QD with ...
Fly ash, also known as "pulverized fuel ash" is one of the coal combustion products, composed of the fine particles that are driven out of the boiler with the flue gases. This paper presents the feasibility of the usage of Quarry Rock Dust as forty percent substitutes for Natural Sand in concrete and cement is replaced by fly ash.
The decrease in workability by the addition of quarry dust is reduced by the addition of fly ash. This paper investigates quantitatively the workability and strength of a concrete mix at 3-day, 7-day, and 28-day age containing 0% - 45% of fine aggregate as quarry dust and …
According to the findings, the author mentioned that the C class fly ash can be effectively used in structural concrete. The rock dust, which is a by-product obtained from the production process of crushed-stone aggregates, is another well-known powder material to be used in concrete.

An experimental investigation has been done to effect of fly ash by partially replacing in cement from 0 to 50% and replacing river sand by quarry dust (0-50%) for …
The mechanical and durability characteristics of the concrete using the three mixtures were analyzed. It has been observed that the mechanical and durability characteristics of a concrete mixture incorporating a fly ash-15%, aluminum dross-10%, and quarry dust-20% are better than that of standard concrete.
It would be beneficial to use fly ash and quarry refuse for making masonry blocks since it would use less energy and cause less environmental damage. The present study emphasizes the combined use of quarry waste ( substitute for river sand) and fly ash (0, 10, 20, 30 and 40% substitute for cement) for sustainable masonry block …
