Due to the elevating demand to replace the conventional cement concrete with any other building material, there has been a continuous effort to promote the properties of geopolymer concrete. The objective of this paper is to reduce the brittleness of geopolymer concrete. This research paper goes for exploring the impact of high and low young's modulus fiber in geopolymer concrete made of M-sand.
M-Sand is used as a replacement of river sand. Alkaline solution (sodium hydroxide, sodium silicate) is used for the preparation of geopolymer concrete. It will act as water in geopolymer concrete. In this experimental work have analyses the strength and durability properties of Fly ash & M-Sand based geopolymer concrete.
The geopolymer concrete with M-sand Constituents is in Figure 1, manufactured by adopting the conventional techniques are used. The fly ash 90%, GGBS (10%) are used, and the fine aggregate River sand are replace M-sand in different percentages of 10, 25, 50, 75 and 100 are used, which are dry mixed together in man mix.
T he absence of carbon in the geopolymer concrete may be due to. dissolution of CO 2 during the polymerization. The reaction of chemical constituents of Fly Ash and M - sand with mixture of sodium ...

proportions of m. sand over river sand in the mix. It was concluded that optimum percentage was complete replacement of river sand by m. sand () [5]. Pattanapong Topark-Ngarm et al . made a special variety of geopolymer concrete by using special grade fly ash with higher calcium content obtained from the ash

Manufactured Sand (M Sand) VSI Crushed Sand -Cubical: Jaw crushed sand -Flaky: ... Mechanical Properties of Geopolymer Concrete with Alternative Materials. Concrete is considered the world's most versatile, durable and reliable construction material, next only to water. It is the most consumed material requiring large quantity of cement, fine ...
Manufacture and test ten reinforced fly ash and M-sand based geopolymer concrete beam under different replacement ratio of sand. Perform calculating on shear strength of geopolymer concrete beams using current code provision and analytical model available for Portland cement concrete members. 3 Methodology.
Laskar & Bhattacharjee studied the rheology of fly ash-based geopolymer concrete with slump varying from 25 mm to flowing concrete with 1–20 M activator strength. They found that the yield stress and plastic viscosity were affected by the molar strength of the sodium hydroxide solution and the ratio of silicate to hydroxide solution.
Geopolymer cement is so special and is completely substituted with flea ash and Ground Granulated Blast-Furnace Slag (GGBS) in the latest research to manufacture geopolymer concrete. Quare sand and M.Sand are substituted for the fine aggregate. Coarse (20 mm) aggregates are replaced by 10 mm coarse.
Geopolymer concrete has good shear strength and the strength values obtained are similar to earlier study [23]. Geopolymer concrete with M-sand has higher shear strength compared to geopolymer concrete with slag sand and pond ash. Table 9. …
Construction time for dome structures made of concrete and hewn stone. From the digging of ancient Roman ruins, one knows that approximately 95% of the concretes and mortars constituting the Roman buildings consist of a very simple lime cement, which hardened slowly through the precipitating action of carbon dioxide CO 2, from the atmosphere.This is a very weak material that …
M20 grade concrete mix meet this requirement when M-sand is used as fine aggregate. Bond strength 13.9 MPa for river sand and 14.1 MPa for M-sand Stress-strain characteristics of concrete The strain corresponding to peak stress is 0.0017 and 0.0021 for the concrete using river sand and M-sand respectively.
