granite cutting as part of the granular structure of Ultra High Performance Concrete (UHPC). The manufactured concrete has a compressive strength greater than 115 MPa. This study substitutes 35%, 70% and of the volume of micronized quartz powder (<40 m) with granite cutting waste.
In this project our main objective is to study the influence of partial replacement of cement with marble powder, and to compare it with the compressive and tensile strength of ordinary M20 concrete. We are also trying to find the percentage of marble powder replaced in concrete that makes the strength of the concrete maximum.
May 10, 2016· Silica fume (SF), marble powder, granite powder and mixed marble and granite powder (MMGP) were used as mineral additives in the preparation of SCC mixes. MP, GP and MMGP are industrial byproducts collected in the form of sludge from local factories in Shaq AlThoaban area, Egypt . MMGP is a mix of marble and granite powders.
Jul 10, 2016· A review on Properties of Sustainable Concrete using granite dust as replacement for river sand A review on Properties of Sustainable Concrete using granite dust as replacement for river sand Singh, Sarbjeet; Nagar, Ravindra; Agrawal, Vinay 00:00:00 Granite dust is a waste produced during cutting and grinding process of granite stone.
partial replacement of coarse aggregate by granite is not only to enhance strength but also to preserve the natural resources of sand and also keeps these powder particles from being airborne into the atmosphere causing health hazard to humans, in particular children . It is widely
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 .
Project on Partial Replacement of Cement with Marble Powder. Jul 3, 2011 In INDIA, the marble and granite stone processing is one of the most thriving industry the So, by partially replacing cement with marble powder, we are proposing a Therefore, specific gravity of fine aggregate =
percentages of waste crushed and granite powder after 7, 14 and 21, 28 and 90 days curing period. Variations in the workability for these different mixes were studied and observed that, increase in the percentage of replacement of granite powder and crushed tiles. KEYWORDS: Cement, Granite powder, Crushed Tiles.
The overall test performance revealed that granite powder can be utilized as a partial replacement of natural sand in high performance concrete. Research Objective Consequently the main objective of this research is to 1) Investigate the potential use of granite powder in concrete as replacement for natural sand.
Effect on Partial Replacement of Fine Aggregate and Cement by Waste Marble Powder/ Granules on Flexural and Split Tensile ... Effect on Partial Replacement of Fine Aggregate and Cement by Waste Marble Powder/ Granules ... WMP in cement is increased by 2 % and for 10% replacement of sand the Flexure Strength in increased by 5%
Use of Crushed Granite Fine as Replacement to River Sand in ... Dec 24, 2010 ... The suitability of Crushed granite fine (CGF) to replace river sand in concrete ... The world wide consumption of sand as fine aggregate in concrete ... namely fly ash, slag, lizenithne powder and siliceous stone powder .
concrete by varying the granite powder as a replacement of sand in the concrete that have originated from granite crushed unites along with admixtures such as silica fume, fly ash, ground granulated blastfurnace slag and superplasticiser as a partial replacement of cement. Research objectives.
1. Expanded Polystrene(EPS): EPS balls are used as an aggregate instead of the crushed stone that is used in regular concrete, it known as EPScrete, EPS concrete or lightweight concrete. It has been used as road bedding, in soil or geostabilizat...
granite powder as an additive together with admixtures to improve the strength of concrete structure. Keywords: concrete properties, fly ash, granite powder, HPC, silica fume, slag I. INTRODUCTION Fine aggregate is an essential component of concrete. The global consumption of natural river sand is very high due to the extensive use of concrete ...
2. For granite powder optimum level of replacement is up to 10% by weight. 3. On addition of different pozzolanic materials (fly ash and granite powder) as a partial replacement of OPC cement the water content required to accomplish the reaction mechanism of cement increases on increasing the percentage of replacement. 4.
This paper examines the possibility of using granite powder as replacement of sand and partial replacement of cement with fly ash, silica fume, slag and superplasticiser in concrete. The ...
Based on findings from the study the partial replacement of Makurdi river sand with 20% CGF is recommended for use in concrete production for use in rigid pavement. Where crushed granite is in abundance and river sand is scarce, the complete replacement river sand with CGF is recommended for use in low to moderately trafficked roads. References
The use of the replacement materials offer cost reduction, energy savings, arguably superior products, and fewer hazards in the environment. In this project our main objective is to study the influence of partial replacement of cement with marble powder, and to compare it with the compressive and tensile strength of ordinary M20 concrete.
for each percentage replacement of cement with marble powder (0%, 5%, 10%, and 15%) and tested for 7days and 28days after curing. From the results it was observed that the compressive strength of concrete increases by the addition of marble powder up to 10% replacement by the weight of cement and then decreases.
For 20% partial replacement of sand with granite powder the increase in the compressive strength was relatively small. The values of compressive strengths of cubes made with different percentages of granite powder replacement of sand are given in Table 5 and also graphically presented in Fig. 4.
Properties of Granite Powder Concrete | nithya rajan ... To study the effect of Granite Powder (GP) on concrete properties, the percentage of granite powder added by weight was 0, 25, 50, 75 and as a replacement of sand used in concrete and cement was replaced with % silica fume, 10% fly ash, 10% slag and the dosage of superplasticiser added 1% by weight of cement.
Nov 26, 2016· V. CONCLUSION From the test results it is clearly evident that granite powder as a partial replacement of sand proves to be beneficial when Durability properties of Concrete is considered. Durability of Concrete using Granite Fines is almost same .
