ABSTRACT Concrete is the most commonly and widely used building material applied in all forms of construction, with an annual production exceeding 2 billion metric tons per year, it is the single most widely used manufactured substance on earth owing to its remarkable versatility as a building material. But the production of raw materials of concrete has certain detrimental effects on environment, mostly the production of cement and coarse aggregated obtained from crushing plants and continuous mining of river beds for getting the natural sand. Eight to 10 percent of the world's total CO2 emissions come from manufacturing cement. The global warming gas is released when limestone and clays are crushed and heated to high temperatures. Whereas production of granitic coarse aggregates on large scales and indiscriminate mining of river beds for sand, to overcome the demand of concrete raw materials has resulted in serious environmental and social problems. Therefore there is an urgent need to find alternative or green materials of concrete to preserve and protect our natural resources for future, by replacing them partially or fully to achieve sustainable development in construction industry. Green concrete is defined as a concrete which uses waste material as at least one of its components, or its production process does not lead to environmental destruction, or it has high performance and life cycle sustainability This paper mainly discusses the potential use of ground granulated blast furnace slag (GGBS), naturally available river pebbles, crushed rock fines (CRF) as partial replacements to cement, sand and coarse aggregates for making green concrete. This research evaluates the strength of hardened concrete, by partially replacing cement by various percentages of ground granulated blast furnace slag, natural sand by CRF and coarse aggregates by river pebbles for M40 grade of concrete at different ages. From this study, it can be concluded that, since the grain size of GGBS is less than that of ordinary Portland cement, its strength at early ages is low, but it continues to gain strength over a long period. The optimum use of green materials as replacement to cement, sand and coarse aggregates is characterized by high compressive strength and good workability Keywords— green concrete, sustainable concrete, GGBS, Crushed rock fines

INTRODUCTION Concrete is one of the major construction materials being utilized worldwide. Concrete is made usually from a properly proportioned mixture of cement, water, fine and coarse aggregates and often, chemical and mineral admixtures. Cement and fine aggregate is the main ingredient used to make concrete, which are obtained from natural resources. Cement is an artificial material manufactured with the naturally available limestone, silica and gypsum. Aggregates are considered one of the main constituents of concrete since they occupy more than 70% of the concrete mix. Due to rapid urbanization in India and countries, construction industry is growing at an alarming rate and in order to meet the requirements of construction materials the mining and quarrying sector has grown rapidly, leading to depletion of the natural resources. Due to heavy increase in construction activities, the crushed granite stone which are the conventional coarse aggregate is under depletion thus causing shortage. In order to meet the sand requirement indiscriminate mining of rivers for sand has become quite common and inevitable. The sand activities have resulted in large number of environmental and social problems. Production of cement on large scale to meet the global demand has led to CO2 emissions thus causing negative environmental effects. To meet the global demand of concrete in the future, it is becoming a challenging task to find suitable alternative construction materials which can fully or partially replace the natural aggregate without affecting the property of concrete and make green concrete for sustainable future. The different materials that can be used as an alternative for natural fine aggregate include blast furnace slag, manufactured sand, crushed glass, copper slag, recycled aggregates, fly ash, steel slag etc. The use of such materials not only result in conservation of natural resources but also helps in maintaining good environmental conditions by effective utilization of these byproducts which will otherwise remain as a waste material. Blast furnace slag is such a material which could be used as a partial replacement for fine aggregate. Blast furnace slag is obtained by quenching molten iron slag (a by-product of iron and steel making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. These materials are otherwise considered to be a potential waste material which is been dumped near the industrial area. Utilization of industrial byproducts and wastes as fine aggregate, coarse aggregate and as supplementary binding materials in concrete has economic, environmental and technical benefits. Research results indicated that the

incorporating these materials in concrete has already been proven to improve the strength and durability performance of concrete. This paper outlines the influence of Ground Granulated Blast furnace Slag (GGBS) as partial replacement to cement, waste river pebbles obtained after sieving sand as partial replacement of coarse aggregate, crushed rock fines(CRF) as partial replacement to natural to sand ; on mechanical properties of concrete. The strength of concrete isdetermined by replacing the main concrete ingredients with alternative materials in various percentages for M40 mix

OBJECTIVES

 Types of waste produced:- The amount/type of waste generated during paper production varies remarkably from mill to mill, because of adopted different recycling rates. However, in Jagiroad Paper Mill, following different types of solid wastes and sludge are produced. They are chiefly generated during wastewater treatment, pulping and deinking processes. 1. Wastewater treatment sludge 2. Lime mud 3. Grits  Materials used:- All the materials have been collected personally, stored properly and procured freshly at the beginning of the study. The materials have been characterized in the Geotechnical Laboratory of Delhi Technological University as well as in Assam Engineering College for assurance. Whereas, environmental engineering laboratory of Delhi Technological University was used to determine chemical properties of lime mud and fly ash 1. Characterization of lime mud 2. Characterization of fly ash 3. Characterization of soil

Methodology

Paper mill waste has been obtained from Ballarpur Industries limited (BILT) Ballarpur, Chandrapur, India. The lime mud thus obtained from these wastes has been used for making bricks by mixing in different weight proportions with another industrial waste: fly ash; obtained from Chandrapur Super Thermal Power Station, chandrapur, Maharashtra, India. The composed mixtures have been adjudged in accordance to Indian Standards (Indian Standard: 1725, 1997). 1. Fabrication of unburnt bricks The brick samples of size 190 × 90 × 90 mm (Indian Standard: 12894, 2002) have been casted in Soil Mechanics laboratory of Delhi Technological University by blending lime mud and soil in 15:85, 20:80, 25:75, 30:70, 35:65 and 40:60 ratios respectively by dry weight. Modular bricks made of lime mud, fly ash and soil have also been casted in ratios of 15:10:75, 20:10:70, 25:10:65, 30:10:60, 35:10:55 and 40:10:50 respectively. The blended samples have been mixed with sufficient quantity of water to obtain working consistency for moulding. The clean mould has been filled with the above mix without allowing any air bubble. The surplus mix has then been removed such that top surface of the mould can be levelled. Since the bricks have been cast by hand, so no pressure has been applied on the mould. The moulded brick has then been allowed to dry for two days in such a manner that there is no direct contact with sun light. After that, the specimens are sun dried for two days and are kept in room temperature for 28 days. Fly ash and cement mixed bricks have been cured by moist jute bags for 7 and 28 days respectively. All bricks are then tested after 28 days for compressive strength as per the provisions of Indian standards (Indian Standard: 3495 (Part 1), 1992). Before testing, the frogs and voids of the specimen have been filled up. A pictorial view of the casted bricks. 2. Fabrication of burnt bricks The non-modular brick samples of size 230 × 110 × 70 mm (Indian Standard: 1077, 1997) have been casted using lime-mud and soil in ratios of 0:100, 5:95, 10:90, 15:85, 20:80, 25:75, 30:70, respectively by volume, at the brick manufacturing site of

M/s Sri Bajrang Brick Manufacturing Company, Jagiroad; just 4 km away from the dumping site of M/s HPCL, Jagiroad Paper Mill. Since the prime motive of the present study is to maximise the usage of lime mud waste as a brick making resource, henceforth, fly ash and cement has been avoided in the soil—lime mud mix for the burnt bricks. The aforementioned blended samples have been mixed with sufficient quantity of water to obtain working consistency for moulding. The clean mould has been filled with the above mix without allowing any air bubble. The surplus mix has then been removed such that top surface of the mould can be levelled. Since the bricks have been cast by hand, so no pressure has been applied on the mould as depicted in Figures 12–14. The moulded brick are dried as per the conventional method as shown in Figure 15 for a week after which the dry bricks have been placed in kiln for burning. All the burnt bricks have been tested for compressive strength and water absorption as per the provisions of Indian standards (Indian Standard: 3495 (Part 1), 1992), respectively. Before testing, the frogs and voids of the specimen have been filled up. 
