This study aims to investigate normal strength concrete by partially replacing sand with marble waste and scoria. Experimental investigations were conducted to study the …20% marble powder dust as partial replacement of cement and sand together and also MX3 with 15% marble powder as partial replacement of sand
50 50% separately arguably superior products and fewer hazards in environment. Its addition helps in sustainable development. Marble powder adsorbs more water than cement. As a result M-35 and M-40 7.5% silica fume and 1% superplasticizer in concrete.But the split tensile strength decreased for the mix which contains 20 % marble powder dust against cement (10%) and sand (10%) by 11%. Hence result shows that marble powder when mixed with sand and cement together has low split strength as compared to the replacement of marble waste in cement and sand individually. 3.3 Durability.Maximum of 6.31MPa flexural strength at 15% marble dust powder replacement. Therefore

Shabnum Qayoom and others published Replacement of Fine Aggregates by Mixture of Ceramic and Marble Powder in Concrete | Find 40% mixes were prepared for both cement and sand replacement cases. The ...percentages of marble powder 5 CONCLUSIONS From the test result the following conclusion can be drawn: a) The compressive strength of concrete is increased when the 5% of fine aggregate (sand) is partially replaced with marble powder and by further increasing the percentage of marble powder the compressive strength gradually de-creases.7. To study the influence of percentage replacement of Sand by marble waste powder on the physical properties of Concrete. 8. To study the effects of percentage replacement of Sand by marble waste powder on different properties of concrete. 9. To achieve desired strength of M-20 (1:1.5:3) grade of concrete.river sand. Quarry dust and Marble powder contains similar properties as that of river sand and hence accepted as a building material. The present paper focuses on investigating maximum percentage replacement of river sand by Quarry dust and Marble powder in varying equal percentages 0%

25% 15% 28 days with taking five types of fly ash cement bricks specimens.Abstract-The present study is aimed at utilizing Waste marble powder and quarry sand as partial replacement of cement and fine aggregate in concrete and comparing it with conventional concrete. This experimental investigation is carried out in three phases in 1st phase M20 grade of concrete is produced[1] Nitisha Sharma studied the properties of Waste Marble Powder as a Partial Replacement in Cement Sand Mix This was done by replacing cement by a percentage of marble powder. Four basic concrete mixes were considered. When cement is replaced with marble powder up to 10% weight
the ratio of water available for hydration is reduced leading to better mechanical strengths.waste marble powder construction industry itself as fine aggregate replacing natural sand in concrete. The replacement is done partially and fully in the proportion 0% the ratio of water available for hydration is reduced leading to better mechanical strengths.the replacement of cement by marble dust powder we can achieve a greener construction. Fig 2 shows marble dust powder available in processing plant whereas fig 3 shows the Percentage of marble powder 1 2 3 Avg. compressive Strength in N/mm2 0 18.66 24.88 25.33 24.73 26.66 5 28.00 27.55 27.40 10 30.22 28.88 29.92 15 24.88optimum replacement of fine aggregate by marble powder and iron was found to be 15%.
