Experimental Investigation of Geo-Polymer Concrete Contains Recycled Aggregate

S. Balamurugan

The main aim of the project is to determine the special concrete made with fly ash. Fly ash is used as cement replacement material varies from 10 % to 40 %. To study the effect of the replaced coarse aggregate and properties of flyash based concrete. Application of recycled materials in the building industry is essential for permanently sustainable development of each country. The use of primary sources and materials is becoming unbearable both economically and ecologically, and therefore it is necessary to seek the possibility of reuse of those materials once their durability expired. The most common use of fly ash is as a replacement for Portland cement used in producing concrete. Concrete made with fly ash is stronger and more durable than traditional concrete. Fly ash concrete is easier to pour, has lower permeability, and resists alkali-silica reaction, which results in a longer service life. Concrete mix design was prepared for the grade of M30. The trial mix was prepare with a constant water binder ratio of 0.35 on superplaticiser was added based on required degree of workability. In the present study, the Geopolymer concrete was prepared by polymerization of sodium hydroxide (NaOH) and sodium silicate (Na2Sio3) with the aid of heat. This research effectively implies the M30grade concrete with the molar concentration of sodium hydroxide and sodium silicate 5M and 6M. The properties of geopolymer concrete are studied. In the present experimental investigation of replacement of cement by fly ash and recycled aggregate has been used to study the effect on Compressive strength, split tensile strength, flexural strength of concrete. For each mix standard sizes of cubes, cylinders and prisms as per Indian standards were cast and tested for Compressive strength, split tensile strength, flexural strength at age of 7 days, 14 days and 28 days as per Indian standard. The research represents the comprehensive summary of extensive studies conducted on fly ash based geopolymer concrete and recycled aggregates. Research data are used to identify the effects of salient factors that influence the properties of geopolymer concrete in the fresh and hardened states. These results are utilized to propose sample for the design of geopolymer concrete mixtures. The most common use of fly ash is as a replacement for Portland cement used in producing concrete. Concrete made with fly ash is stronger and more durable than traditional concrete. Fly ash concrete is easier to pour, has lower permeability, and resists alkali-silica reaction, which results in a longer service life.
