sieved by IS: 90 sieve before mixing in concrete. Stone dust is of grey colour and shape of particles is irregular. Properties are mentioned in Table 215. Results and discussion Compressive strength with replacement of fine aggregate with stone dust: The result of compressive strength with replacement of stone dust for 7 and 28 d are shown in
Behaviour of Concrete on Replacement of Sand with Quarry Stone Dust as Fine Aggregate B. V. Vijeswara Rao1 V. Rama Chandra2 1PG Student 2Assistant Professor 1 Department of Structural Engineering2 Civil 1,2VITAM College of Engineering, Mindivanipalem(V), Sontyam(P), Anandapuram (M), Visakhapatnam - 531173, (A.P), India
Aug 11, 2018· [1] FINE AGGREGATE. Fine Aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category.
May 22, 2017· The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduc...
50% replacement of sand by quarry dust gives higher compressive strength than natural sand concrete. Key Words: Concrete, quarry dust, river sand, compressive strength, replacement. 1.INTRODUCTION The motive of this study is to determine the effect of quarry dust in concrete as fine aggregate .
used as fine aggregate in concrete and also found that quarry dust reduces the cost without affecting the strength of concrete. Hiroshi Uchikawa (1996) studied the influence of microstructure on the physical properties of concrete prepared by substituting mineral powder for part of fine aggregate. The hydration reaction of cement, hardened
investigation on concrete with stone crusher dust as . investigation on concrete with stone crusher dust as fine aggregate d s prakashrao Investigations on concrete with stone crusher dust as fine Jul 01, 2004 Stone crusher dust, which is available abundantly from crusher units at a low cost in many areas, provides a viable alternative for river sand in concrete.
stone dust as partial replacement of fine aggregate in concrete. To accomplish this specimen were cast for different replacement level at an interval of 10 percent to determine workability and compressive strength of concrete at different level of fine aggregate with stone dust. The percentage of stone dust .
This project describes the feasibility of using the marble sludge dust in concrete production as partial replacement of fine aggregate. In INDIA, the marble and granite stone processing is one of the most thriving industry the effects if varying marble dust contents on the physical and mechanical properties of fresh and hardened concrete have ...
1. For the designed mix proportions of M25 and M40 grades of concrete the desired characteristic strengths for cubes are achieved in both conventional concrete and Quarry Stone dust concrete. 2. The strength achieved in concrete made with sand as fine aggregate achieved high strengths when compared with Quarry stone dust concrete.
It is observed that the compressive strength of concrete made using 10% recycled aggregate and 60% stone dust as replacement of coarse aggregate and fine aggregate respectively, is about 11% more ...
After 45% replacement of fine aggregate with clastic stone powder when I compared the results, the difference between the 0% and 45% replacement of fine aggregate with stone powder, the compressive strength I got after 7 days of curing was 10.94% and that of after 28 days of curing it .
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-two (72) 100 mm cubes were cast and cured in water up to 28 days. The Compressive strength test was done on the first 36 cubes at 7, 14 and 28 days, while the remaining 36 cubes were exposed to 5 % ...
dust material in concrete. The replacement of fine aggregates with saw dust can be beneficial for the building components. Thus, the properties such as 2.workability, compression test, elongation index etc. of concrete changes. 2. OBJECTIVES 1) To prepare light weight saw dust concrete of nearly
stone dust and waste foundry sand as fine aggregate replacement. Fine aggregate are replaced partially with stone dust and waste foundry sand. The percentages of replacement 0%, 20%, 30%, 40%, 50% by weight of fine aggregate with stone dust and 0%, 10%, 15%, 20%, 25% by weight of fine aggregate with waste foundry sand. The fresh properties like ...
The machine has a screen that traps the larger material (that is, the crushed stone). The smaller material or "screenings" falls through the screen. Depending on the size of the holes in the screen used, it can be so fine in texture that it is basically a powder. This is what you are buying as "stone dust." But it may go by other names, such as:
May 14, 2020· A control concrete mix was proportioned using natural aggregates and the OPC 43-grade cement that is without the addition of stone dust and silica fume for comparison purpose. First, the binary mixes were prepared by replacing fine aggregates with stone dust to optimize fine aggregates replacement.
