The concrete mix made using granite powder (GP) and iron powder (IP) as partial replacement of sand showed good workability and fluidity similar to normal concrete mixes. 2. The compressive strength of concrete increased with the addition of granite powder (GP) as partial replacement of sand.
Two grades of concrete M20 and M25 having nominal mix proportion of 1::3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to in step of 10%.
To study the effect of the addition of granite dust into the concrete mixture, part of the sand was replaced by granite dust in the amount of 200 kg/m 3 (mixes 32,5G200 and 42,5G200) and 300 kg/m 3 in mixtures 32,5G300 and 42,5G300. The water/cement ratio in all types of mixes was 0,51.
The main parameter investigated in this study is M30 grade concrete with replacement of sand by granite powder by 0, 25 and 50% and cement was partial replacement with silica fume, fly ash, slag and super plasticizer. This paper presents a detailed experimental study on compressive strength, split tensile strength 28, 56 and 90 days.
Jul 15, 2020· 1:2:4 therefore means, 1 part of cement : 2 part of fine aggregate : 4 part of coarse aggregate. This ''part'' as used refers to volume. It means If I have 1 headpan of cement, I''ll need 2 headpan of sharp sand and 4 headpans of granite / gravel or 1 cup of cement, 2 cups and 4 cups respectively of sand and stone.
Stone dust is not used in good concrete especially in '' Controlled Concrete ''. Use of Stone dust is going to drastically reduce the workability of concrete. This is so because the stone dust particles are not rounded like natural sand particles bu...
Crushed granite may be sold on its own or with a stabilizing material (such as dust fines) for binding properties. Crushed Granite Benefits. Crushed granite is ideally suited for driveway installations for several specific reasons. Some of the benefits to using crushed granite for driveways include:
Sand was replaced by mass fractions of 0, 5, 10, 15, 20, 30 and 40% with granite dust. The study reflected that replacement of sand by granite dust up to 20% showed better strength than conventional concrete. The comparison study of bond strength with and without replacement of granite dust using different diameters of TMT bars was carried out.
Using Sand Between Patio Pavers. Sand between pavers will compact to a degree, yet still remain porous enough for good drainage. Typically concrete sand is used as a base layer and leveling medium for patios and walkways made of concrete paving stones. Once applied between the pavers, the excess is easy to sweep away.
Kala conducted tests on granite powder as a partial sand replacement in high performance concrete and showed the beneficial effects on its mechanical properties. Of all the six mixtures he considered, concrete with 25% of granite powder (GP25) was found to be superior to other percentages of granite powder concrete as well as conventional.
To study the effect of the addition of granite dust into the concrete mixture, part of the sand was replaced by granite dust in the amount of 200 kg/m 3 (mixes 32,5G200 and 42,5G200) and 300 kg/m 3 in mixtures 32,5G300 and 42,5G300. The water/cement ratio in all types of mixes was 0,51. The components of concrete mixtures are shown in Table 2.
In order to study the strength behaviour and fire resistance of the concrete made with full replacement of sand with Quarry stone dust the tests are conducted. Results so obtained for the tests conducted on cubes and prisms for M25 and M40 grades of concrete with various dosages of super plasticiser at 7days and 28 days were tabulated.

Stone, crushed Volume to Weight conversions.
The concrete mix made using granite powder (GP) and iron powder (IP) as partial replacement of sand showed good workability and fluidity similar to normal concrete mixes. 2. The compressive strength of concrete increased with the addition of granite powder (GP) as partial replacement of sand.
Sharp sand is now unsustainable due to largescale depletion and this creates environmental problems. As environmental concerns and other constraints make the availability and use of sharp sand less attractive, a substitute or replacement product for concrete industry needs to be found. Sharp sand is most commonly used as fine aggregates in the production of concrete and an adequate substitute ...
An experimental study on the high performance concrete made with granite powder as fine aggregate and partial replacement of cement with % silica fume, 10% fly ash and 10% slag subjected to water curing is conducted for finding the mechanical properties such as compressive strength, split tensile strength, modulus of elasticity, flexural strength and water absorption characteristics of concrete mixtures.
Test results showed that concrete with high MSand content provides better results than controlled concrete and Granite powder can be used up to 10% with suitable MSand .
Granite dust cement replacement or addition of %, %, % and % were used. The test results showed an improvement on concrete compressive strength at % granite dust as cement replacement and improvement on compressive strength at most levels of granite dust .
