“A Study On The Effect Of Strength Of Concrete By Partially Replacing Cement With Waste Glass And Check The Effect Of Ammonium Nitrate On Concrete”

Abstract

In order to determine how waste glass affected the mechanical qualities of the concrete, tests
for compressive strength, splitting tensile strength, and flexural strength were carried out. This goal led to
the initial usage of waste glass powder (WGP) in place of some cement, with three distinct ratios of WGP
being employed in the manufacturing of concrete: 5%, 15%, and 25%.In order to investigate the
combined impact of varying WGP ratios on concrete performance, mixed samples (5%, 15%, and 25%)
were created by substituting WGP and crushed glass particles for cement, fine and coarse aggregates, and
cement. In its fresh form, the workability and slump values of concrete made with various percentages of
leftover glass were measured and contrasted with those of plain concrete. The compressive and splitting
tensile strengths of the hardened concrete made from waste glass were measured using 6 inch by 6 inch
by 6 inch cubic specimens and cylindrical specimens with a 6 inch diameter and a 12 inch height.Based
on the acquired data, the ideal dosage can be thought of as 15% WGP replacement for cement.
Conversely, the mechanical qualities of concrete made with a combination of crushed glass particles and
WGP rose up to a certain point before declining due to poor workability. As a result, 5% is thought to be
the ideal replacement level since combined waste glass exhibits much higher strength and improved
workability qualities. The discarded glass and cementitious concrete showed good adherence. Finally,
useful empirical formulas have been created to calculate the flexure, splitting tensile, and compressive
strengths of concrete containing various percentages of waste glass. using the use of suggested expressions, it is simple to estimate these strength values of the concrete made using glass powder during
the design stage as opposed to performing an experiment. Ammonium nitrate can have a detrimental
effect on concrete when it comes into contact with moisture. The presence of ammonium nitrate can lead
to a chemical reaction known as ammonium nitrate attack, which causes the concrete to deteriorate and
crack over time. This reaction occurs due to the formation of expansive compounds within the concrete,
compromising its structural integrity. In severe cases, this can lead to significant damage and even
structural failure of the concrete. Therefore, it's important to prevent the contact of ammonium nitrate
with concrete, especially in environments where this chemical is present, such as in fertilizer storage
facilities or areas where explosive materials are handled.
