Fly ash and Blast Furnace Slag for Cement Manufacturing 1 Introduction 1.1 Context of this project The UK Government in close cooperation with the energy-intensive industrial sectors has developed Decarbonisation Roadmaps. In this present experimental work an attempt is made to replace cement by GGBS to overcome these problems. The most widely used specification for fly ash in North America is ASTM C618 Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete (AASHTO M 295). The materials used in this experiment were GGBS, FLY ASH, fine aggregate, coarse aggregate and water. <>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 842.04] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> <>>> 2 . Fly Ash concrete is resistant to acid and sulphate attacks. Its well- graded and that all sizes grains are well distributed in a given sample. Fly ash in concrete contributes to a stronger, more durable, and more chemical resistant concrete mix. Mix Design calculation procedure is the same when either GGBS or Fly ash are used, the only change will be the specific gravity of the admixture. By B Prabu, R Kumutha and K Vijai. cement by Fly Ash (FAC1), concrete made by replacing 40% of cement by Fly Ash (FAC2), concrete made by replac ing. The blended cement can be supplied as a pre-blended factory produced product or be prepared in the mixer by … The slag powder does not contain carbon, so it will not affect the stability of the air content of the concrete. 4 0 obj Fly ash and GGBS are widely employed in concrete production. Read also: Difference between Clay Bricks vs. 0.50 and 0.65), which was the main basis of comparison, and combinations of CEM I with GGBS (at levels of 35%, 55% and 75%), and fly ash and LS part-replacing this (at levels of 10 to 20 % and 10 to 35% respectively), after consideration of the relevant standards and related research. GGBS level for binary concretes compared to CEM I. Fig: 1 Chemical Properties of Cement, GGBS,FLY ASH Table: 2 Comparative Analysis Of Ggbs And Fly Ash Si.no Title of the project Journals name Author name Year of GGBS provides greater mechanical and durability properties. 2 0 obj Fly Ash Bricks. GGBS is obtained from Toshali Cements Pvt ltd, Bayyavaram, India and Fly ash from National thermal power plant, Ramagundam, India. Abstract. Geopolymer Concrete (GC) is an innovative and Eco-friendly construction material and an alternative to Portland cement concrete. endobj GGBS and fly ash contain of bacteria of 106 bacillus pasteurii in M40 mix. Fly ash is replaced by GGBS in the range of 25%, 50% and 75%. 5-12This study is aimed at investigating the effect of various curing methods on the mechanical properties of fiber reinforced geopolymer concrete samples.

Specific gravity of GGBS and Fly ash are 2.90 and 2.17 respectively. A contrast study was carried out for the concrete (GGFAC) incorporating FA and GGBS, control Portland cement concrete and high-volume FA high-strength concrete (HFAC). The current experimental evaluation scrutinizes the effectiveness of fly ash and GGBS on the improvement of workability, compressive strength and durability performances of SCGC. The use of fly ash gives concrete good work ability, durability and finish. GGBS content at less than 25% was found to slightly influence the consistency and compressive strength of GRAC. The mixes covered a range of w/c ratios (0.35. GGBS-Fly Ash concrete is slightly higher compared to control mix. %���� Literature Review 3.1 Etaveni Madhavi From the experiments conducted, replacement of FLY ASH and GGBS as cement can be optimized. Replaced concrete were tested with the slump, compaction factor, Vee-bee and compressive strength. The replacement of 15%, 20% and 25% fly ash with ground granulated blast furnace slag (GGBS) and the addition of 5%, 10% and 15% of glass powder have been done and cured under ambient curing. From Fig. Comparing the mechanical properties with GGBS as an mineral admixture, Fly ash as mineral admixture and with combination of fly ash & GGBS as an mineral admixture. The chemical and physical properties Fly ash and GGBS are as given in Table I . We at “Conash Infrastructure” are quality cautious and reliable supplier for cost effective supply of Fly Ash to Indian market as well as exports. Another major hurdle of extensive use of GGBS concrete lies in the little source of supply of GGBS. Fly ash and GGBS are used as binders in this research work. Fly Ash Bricks. GGBS and fly ash are two cement replacements which are grown in popularity. Consistence (Slump) While concretes containing GGBS have a similar, or slightly improved consistence to equivalent Portland cement CEM I concretes, fresh concrete containing GGBS tends to require less energy for movement. These results are discussed with reference to pore structure measurements, which show the PFA concrete to have a coarser pore structure than the OPC concrete close to the surface—at depth the situation is reversed. In addition, there may be higher water demand of GGBS in fly ash-GGBS based GPC because of its larger surface area as compared to fly ash . The binders such as fly ash, Ground Granulated Blast Furnace Slag (GGBS), and cement used to produce GC in this research work. The differences in rheological behaviour between GGBS and Portland cement CEM I may enable a small reduction in water content to achieve an equivalent consistence class. And t he illustrated SEM micrographs reveal that fly ash particles as shown in Fig. P. Fly ash [12,16,17], GGBS [18,19], calcined clays [20,21], and other by-products [22,23] from recycled waste, as geopolymers, have been investigated by different researchers. The report models supply and demand for fly ash and granulated blast furnace slag up to 2030. GGBS/fly ash ratio has a significant influence on the fresh and hardened properties of GRAC.
