The portland pozzolana cement is being sold in the market as 53MPa, composite cement etc. In recent studies, many researchers found that the use of additional cementitious materials likes fly ash in concrete is economical and reliable. Thirty percentage of replacement fly … It is expected that very soon production of fly ash in, India will reach 400 MT per annum. PPC CEMENT : OPC CEMENT : Description : PPC is a variation of OPC which includes a mixture of pozzolanic material which is known to increase the strength of concrete. The geotechnical testing program included the classification tests, the compaction test, the consolidation test, and the permeability test. Protecting the environment and conserving natural resources are at the heart of any development. Hydrochloric acid – Sp gt 1.16 (conforming to IS : 265-1976) 2. INTRODUCTION Fly ash can substitute up to 66% of cement in the construction of dams. However, all these strength properties and abrasion resistance showed continuous and significant improvement at the ages of 91 and 365 days, which was most probably due to the pozzolanic reaction of fly ash. Removal of suspension from ash slurry in Effluent of stream Generation plant, Despande, V.P. PORTLAND POZZOLANA CEMENT – FLY ASH BASED No. The inclusion of silica fum, permeability of concrete containing lime and silica. produced in India and disposed off by landfilling or dumping in and around sites. Generally speaking, currently in the concrete industry, the percentage of fly ash as part of the total cementing materials in concrete normally ranges from 15 to 25%, although it can go up to 30-35% in some applications. outlines the composition of the composite material, method of preparation of mortar specimen, testing procedure and SureBuild. Rapid Chloride Permeability Test (RCPT) was carried out for measuring durability of concrete. This paper Plastic waste fibers (PWF) are wastes from used polythene bags, tins, packets and rubber. of Amendments : 1 2. So it is very important to dispose these wastes without affecting the environment. It is reported that there is still a huge proportion of fly ash produced in Compressive strength, workability and durability of the prepared mixes were determined. Another benefit is the fly ash reduces the permeability of the hardened concrete, so it is slightly more durable. Since Fly ash is a slow reactive pozzolans. Some of the problems associated with Fly ash are large area of land required for disposal and toxicity associated with heavy metal leached to groundwater. civil engineering applications such as concrete making, cement manufacture and embankment etc. Concrete is the most used construction material used in rigid pavement. Keywords: Fly ash, PPC Cement, Thermal Power plants, Compressive Strength, Concrete Mix Design 1. These percentages represent the approximate limits where minimum compressive strength and integrity of the concrete pipe sections (immediately after removal of the forms) can be achieved. 48 specimens of sizes 150*150*150mm and 300*150mm were made for testing compressive strength and split tensile strength of the concrete. ... Compressive strength and split tensile strength of concrete with plastic waste as aggregate and observed a good strength gain. Materials having potential for gainful utilization remain in the category of waste till its potential is understood and is put to right use. energy and abrasion resistance can be obtained by using BF even at low contents. Emission, effect and the global warming, hence it is, recycle & reuse of fly ash are being formulated. The binders are eminently suitable for partial replacement (up to 25%) of the cement in concrete without any detrimental affect on the strength. Whatever your building need, there’s a bag for that in the new PPC sure range. Publ. “Effect of fly ash on, 2000 “Specifications for plain and reinforced concrete. So, the main components are OPC clinker, gypsum and pozzolanic materials (15~35%) which includes calcined clay, volcanic ash, fly ash or silica fumes. As a result, solid waste management has become one of the major environmental concerns in the world. A quite strong relationship was established between abrasive wear and void content and flexural strength of concretes. It was also observed that up to 30% replacement of PPC by fly ash strength is almost equal to referral concrete after 56 d. PPC gained strength after the 56 d curing because of slow hydration process. This plastic waste leads to pollute the environment. Strength properties and hydration of the cementitious binder studied at room temperature and at 50 °C in over 90% R.H are presented. The effect of addition of calcined clay in these types of binders was studied. Section: 1. Since the partial replacement of cement or aggregates, attempts at concrete ash, crushed concrete, glass waste, rice husks, etc. Besides, the major component of the OPC is naturally available, hence limited in terms of resources . There is no direct method for the determination of Fly Ash content in the PPC. Result showed that PPC can be replaced up to 40% by fly ash without considerable change in compressive strength. It is expected that very soon production of fly ash in India will reach 400 MT per annum. SureBuild. In this experimental works we are comparing the properties of super plasticizer based concrete with that of without super plasticizer added concrete. 2012. The addition of lime and silica fume also improved the sorptivity of concrete.Through the use of differential scanning calorimetry and thermogravimetric analysis (DSC/TG), it was demonstrated that the addition of hydrated lime increased the Ca(OH)2 content; whereas the addition of silica fume decreased the Ca(OH)2 content in the cement paste. softening sludge (lime sludge) has been utilized in mortar. 403-424.1978, Parveen1, Vivek2, Bhupinder Singh3, " Effect of Fly Ash in PPC Concrete " International Journal of Recent Development in Engineering and SureWall . Journal of Sustainable Cement-Based Materials. Fly ash, being treated as waste and a source of air and water pollution till recent past, is in fact a resource material and has also proven its worth over a period of time. The strength is futher increased in the presence of a, As civil engineer's maintaining our duty to discover method of making concrete at lowest water cement ratio while maintain a required workability. PORTLAND POZZOLANA CEMENT – FLY ASH BASED No. "Removal of suspension from ash slurry in Effluent of stream Generation plant. Technically PPC has considerable advantages over OPC when made by using optimum percentage of right quality of fly ash. High strength concrete is gaining popularity over normal strength concrete in the design of various structural components because of its advantageous nature. In this paper, investigations were undertaken to formulate cementitious binder by judicious blending of fly ash with Portland cement as well as by admixing fly ash with calcined phosphogypsum, fluorogypsum, lime sludge, and chemical activators of different finenesses. According to, Utilization of waste materials in concrete. The air permeability of concrete containing lime and silica fume either decreased or remained almost the same when compared to the concrete without these. The percentage of fly ash in PPC permitted by IS: 1489 varies from 15 per cent (minimum) to 35 percent (maximum). It is considered that this material can be used as a supplementary material as partial replacement of cement in the construction industry in different areas. Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash. The rest of the figures on slump variations are presented in supplementary section (Fig. The only exception was the deicing salt-scaling test in which the performance of the concretes investigated was less than satisfactory. Premium Quality cement. Thirty percentage replacement of fly ash exhibited the highest compressive strength, splitting tensile strength and elastic modulus. The results indicate that high-strength SCC can be achieved using a carefully designed ternary binder system (made with cement, fly ash, and silica fume), water-reducing admixture, and low water-to-binder ratio (W/B = 0.20). However, based on the past test results of insoluble Residue in the PPC, Fly Ash content in the supplied PPC may be obtained. The inclusion of silica fume was also found to increase the 28 days strength significantly. Portland Pozzolana Cement (PPC) by fly ash strength increased marginally (1.9% to 3.2%) at 28 and 56 d respectively. Finally, using the plotted contours, a mix design process has been organized into five simple steps that can easily be followed in order to proportion an optimized ratio of cement, aggregate and SCMs for preparing durable and economical concrete mixes. So in one bag of PPC Cement of 50 kg, you will have max 17.5 kg flyash and rest is cement.

Leaching of alkalis is reduced and the alkaline environment around steel … In the present study it was intended to explore the possibility of utilization of fly ash in concrete using Portland pozzolana cement (PPC). The beam specimens (100 mm x 100 mm x 500 mm) were cast and tested for determination of flexural strength of concrete at different replacement levels. The morphology of the fly ash particles was studied by scanning electron microscopy. It is mostly grown in the Indian subcontinent, Brazil, eastern and southern Africa and some parts of the United States (Hawaii and Florida). The fly ash to be used for manufacturing of PPC should conform to IS:3812 (Part I) – 2003. Three percentages of san fibers (0.25%, 0.50% and 0.75%) having 25-mm length were used.The test results indicated that the replacement of cement with fly ash increased the workability (slump and Vebe time), decreased compressive strength, splitting tensile strength and flexural strength and had no significant effect on the impact strength of plain (control) concrete. This paper presents the results of an experimental investigation on the properties of fly ash concrete incorporating either hydrated lime or silica fume to improve the early strength of concrete.
