Crusher dust, or quarried and crushed rock too small for use on roadbeds, makes an excellent material for a pathway. Rain, time, and foot traffic will cause it to harden to near concrete firmness. Read on to explore pathway ideas and learn how to employ crusher dust in your pathway project.
Compressive strength at 50 percent replacement of fine aggregate with stone dust is comparable to the referral concrete (Abbas et al 2015).Workability of concrete decreases within 1 – 6 percent with increase in quantity of crusher dust as partial replacement of natural sand (Pofale et al 2013).
The only way is to search an alternatives material which can fully or partially replaced naturally available material in construction. Stone dust is such an alternative material which can be effectively being used in construction as partial replacement of natural sand. This is a waste product obtained from aggregate crushing plant.
Ultrasonic pulse velocity test for complete replacement of sand by crushed stone dust shows excellent results [9]. The stress-strain curve for both natural sand and quarry dust shows similar ...
Lots of research has been done regarding the crusher dust as alternative materials for river sand and reported that crushed stone dust can be used to partially replace the natural sand in concrete. Saw dust and robo sand in proportion used as fine aggregates in concrete and the compressive and split tensile strength were tested.
The purpose of this study is to evaluate the performance of stone powder (substitute) in concrete when mixed with concrete to ensure workability, durability, and strength of concrete using OPC (class 43). Efforts to improve concrete performance in recent years suggest that natural substitutes for sand, combined with grout, can improve the strength …
It was concluded that the concrete made with 20% replacement of sand by crusher dust and 20% replacement of broken stone by gravel gave better results in terms of strength and cost.

The replacements of natural sand by waste quarry dust and marble powder will help to resolve environmental, economic and ecological issues of concrete production and will lead towards sustainability.
Quarry dust is a waste from the stone crushing unit accounts 25% of the final product from stone crushing unit. This quarry dust which is released directly into environment can cause environmental ...
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 natural sand in preparation ...
Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve. Effects of dust content in aggregate on properties of fresh and hardened concrete are not known very well. An experimental study was undertaken to find out the …
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 silica or sand, stone crusher dust, filtered sand, treated and sieved silt removed from reservoirs as well as dams besides sand from other water bodies.
For the purpose of experimentation M30, M40 grade concrete is designed for 25,50,75, replacement of natural sand by quarry dust and waste plastic in 2,4,6,8 % variation. .

With modern crushing technologies, recycled crushed stone aggregates can match the quality of new ones. This means the construction project's strength, durability, and performance won't be saced.
The optimum value of ceramic waste is achieved by 20% with stone dust. In recycled concrete, complete replacement of conventional fine aggregate by stone dust and ceramic waste is possible to achieve strength as per mix design. In recycled aggregate concrete optimum ratio of stone dust to ceramic waste is 4:1.
