3. ABSTRACT 2

4. Ordinary Portland cement (OPC) is conventionally used as the primary binder to produce concrete. The amount of the Co2 released during the manufacture of OPC due to the calcinations of limestone and combustion of fossil fuel is in the order of one ton for every ton of OPC produced. Attempts are made to reduce the use of Portland cement in concrete are receiving much attention due to environment-related. In the present study Metakaolin and marble dust used as a partial replacement for cement. Metakaolin is a calcined clay and It is a Dehydroxylated form of the clay mineral Kaolinite. Stone having higher percentage of Kaolinite are known as china clay or kaolin was traditionally used in the manufacture of porcelain ceramic material. The particle size of Metakaolin is smaller than cement particles and whereas Marble dust is obtained from cutting and manufacturing industries of marble. In India near about 3500 metric tons of marble dust slurry per day is generated. So, Marble dust is very easily available with very less cost. Kaolinite is also called as green pozzolana because it emits less co2. This paper presents results of an experimental program to determine mechanical properties of concrete with metakaoline and marble dust is replaced with cement with the known percentages such as 0%,5%+5%,7.5%+7.5%,10%+10%,12.5%+12.5%,15%+15% for the grade of M30 . Key Words : Metakaolin, Marble Powder, Compressive strength, Split-Tensile strength. ABSTRACT

5. 2 OBJECTIVE& INTRODUCTION

6. Background on Concrete and its Limitations : The high Water consumption needed for mixing concrete is another drawback, particularly in areas with limited water resources. the use of steel reinforcements to compensate for this weakness. Additionally, concrete exhibits brittleness , meaning it offers minimal resistance before fracturing under impact or excessive loads. Finally, concrete's poor thermal insulation properties can contribute to energy inefficiency in buildings. INTRODUCTION

7. OBJECTIVE This research delves into the potential benefits of using metakaolin and marble dust as partial cement replacements. The primary objectives are to investigate the effects of these replacements on the following key properties of concrete:  Strength: Will these replacements enhance or diminish the compressive and tensile strength of concrete? Durability: How will they influence the concrete's resistance to factors like chloride penetration and freeze-thaw cycles? Environmental Impact: Can utilizing these replacements reduce the CO2 footprint associated with concrete production?

8. LITERATURE REVIEW 2

9. Abdullah Anwar et.al (2014)  In this paper the authors represented that Marble Dust Powder has replaced the (OPC & PPC) cement of 0%, 5%, 10%, 15% 20%, & 25% by weight & M-20 grade concrete was used. Concrete is M30. mixtures were developed, tested and compared in terms of compressive strength to the conventional concrete Sanjay N. Patil et.al (2014)  The paper deals with the use of Metakaolin which is having good pozzolanic activity and is a good material for the production of high strength concrete. Use of MK is getting popularity because of its positive effect on various properties of concrete. J.M. Khatib et .al (2012)  In the paper author studied the compressive strength, density and ultrasonic pulse velocity of mortar containing high volume of Metakaolin (MK) as partial substitution of cement. In this paper up to 50% of MK was used to replace cement in increment of 10. After De-molding, specimens were cured in water at 20°C for a total period of 28 days. The density seems to reduce with the increase of MK content especially at MK content above 30%.

10. MATERIALS

11. MARBLE DUST It is an essential component of igneous and metamorphic rocks. The size varies from specimens weighing a metric ton to minute particles that sparkle in rock surfaces. The crushed marble powder used in the experiments is in a form of white powdered, which replaces fine aggregate from the conventional concrete. The particle size used ranges from 10 to 45μm Construction Waste  Environmental Protection Agency (EPA) defines construction and demolition (C&D) waste as waste materials consist of the debris generated during the construction, renovation, and demolition of buildings, roads, and bridges. C&D materials often contain materials that include: concrete, asphalt, wood, metals, gypsum, plastics and salvaged building components. It is a challenging task to handle C&D waste because it is bulky, heavy and inert and also mixture of various materials of different characteristics. It is also difficult to choose any suitable disposal method, for example, it cannot be incinerated due to its high density and inertness.

12. METAKAOLIN Metakaolin is a high-quality pozzolanic material. Metakaolin is one of the most widely used mineral admixtures these days. It helps concrete obtain both higher performance and economy. Kaolin clay is the raw material for the Metakaolin. Kaolinite clay is a mineral which is fine and white in colour and it is used in the manufacturing of porcelain. Kaolinite clay is also known as china clay or kaolin clay.

13. CEMENT Cement is the important building material in today’s construction world 53 grade Ordinary Portland Cement (OPC) conforming to ([17] IS: 8112-1989). Cement is a binder, a substance used in construction that sets and hardens and can bind other materials together. The most important types of cement are used as a component in the production of mortar in masonry, and of concrete, which is a combination of cement and an aggregate to form a strong building material.

14. AGGREGATES The crushed aggregate was used from the local quarry. In this experiment the aggregate was used of 20mm down and tested as per IS: 2386-1963(I, II, III) specification. It is the aggregate most of which passes 4.75 mm IS sieve and contains only so much coarser as is permitted by specification. 1. it is the aggregate resulting from the natural disintegration of rock and which has been deposited by streams or glacial agencies 2. Crushed Stone Sand– it is the fine aggregate produced by crushing hard stone.

15. WATER It is an essential component of igneous and metamorphic rocks. The size varies from specimens weighing a metric ton to minute particles that sparkle in rock surfaces. The crushed marble powder used in the experiments is in a form of white powdered marble flour, which replaces fine aggregate from the conventional concrete. The particle size used ranges from 10 to 45μm

23. Decide the Target Strength for Mix Proportioning The average target compressive strength of the concrete mix after 28 days of curing can be determined using the following formula: F’ck = fck + 1.65 x S F’ck = The target average compressive strength at reaching 28 days of curing.  Fck = Characteristic compressive strength at reaching 28 days of curing.  S = Assumed standard deviation , per Table 1 of IS 10262 –

39. CONCLUSION 2

40. The replacement of cement with 9%MK and 10% MP, give better results better for strength 2. If the percentage of MK is increased above 9% keeping the percentage of MP as10%, there is reduction in strength of concrete. 3. The permeability test shows that there is decrease in permeability of concrete with the increase in amount of Metakaolin and Marble powder addition as shown in fig 9. 4. The optimum percentage for replacement of cement with Metakaolin and Marble powder was 9% and 10 % respectively for both cubes and cylinders. After 9%MK & 10% MP, compressive strength as well as split tensile strength starts decreasing. 5. There is decrease in strength after 9% replacement of MK and 10% replacements of MP but durability properties go on increase with increase in percentage of MK-MP. 6. Use of Metakaolin and Marble powder give GREEN CONCRETE. 7. Use of MK and MP save our environment, since during the production of MK and MP there is no emission of carbon dioxide. 8. RCMT results shows that concrete made of addition of MK-MP has very less rate of penetration of chloride ions. Hence Rate of penetration goes on decrease with increase of percentage of MK-MP in concrete as shown in fig. 9. So we can say more durable concrete is obtained.
