Evaluation of the Possibility of Replacing Fly Ash with Glass Powder in Lower-Strength Concrete Mixes

Abstract

This article presents the results of research on the possibility of replacing fly ash with recycled waste glass in lower-strength concrete mixes. The results of testing concrete mixes containing either waste-glass powder or fly ash are presented in the article. A standard C12/15 concrete mix was chosen for the tests based on its common use for producing concrete for footings to support road kerbs and gutters along national roads in the Polish province of West Pomerania. In the first step of the testing procedure, reference mixes were prepared with 22.5% and 45% fly ash in relation to the content of cement. In the next step, mixes were prepared based on the same specification, except that glass powder was added in place of fly ash. The samples were then tested to determine the influence of waste-glass powder on the main properties of the prepared concrete mixes and on the performance of the concrete when hardened. All the samples were tested for 7 and 28-day compressive strength, water absorption, and freeze-thaw resistance in water. Next, the performance parameters of the samples containing waste-glass powder were compared to the reference mixes containing an equal amount of fly ash. The test results and their analysis allow us to conclude that mixes containing glass powder are not only equal to mixes containing fly ash, but even outperform them by a wide margin in terms of durability.

A Review on Using ANOVA and RSM Modelling in The Glass Powder Replacement of The Concrete Ingredients

“…The accepted research program largely comprised the description of the concrete compressive strength, water absorption and freezethaw confrontation after 25 and 100 cycles of freezing and thawing. Up to the chosen system, the features of air voids in toughened concrete were also defined [10] The outcomes displayed the production of 1-ton cement incompletely substituted by glass powder particles needs less energy than the cement somewhat substituted by limestone. In the end, conferring to research, usage of the glass powder deposit in the producing of fibres cement compounds may offer significant technical, environmental and economic assistance.…”

Life Cycle Assessment of Waste Glass Powder Incorporation on Concrete: A Bridge Retrofit Study Case

“…Tariq et al [13] identified greater resistance to chloride penetration in concrete with the incorporation of waste glass than in concrete with fly ash and justified that this is due to the continuous evolution and refinement of the pore structure, which results in better long-term transport performance of the binder system and considerable extension in terms of service-life for concrete exposed to marine environment. Jurczak and Szmatuła [14] compared the use of fly ash incorporation with waste glass in concrete and identified that there were no significant differences in terms of compressive strength for the concrete class adopted. Ahmad et al [15] identified a gain in compressive strength of 27% in concrete with the replacement of 20% cement with glass waste.…”

Experimental and Finite Element Analysis of External ALC Panel Steel Frames with New Semi-Rigid Connector

“…With urbanization accelerating, traditional construction techniques cannot meet the current increasing demand for housing. Prefabricated building is considered a major trend for future development because of its good seismic performance, easy construction, low greenhouse gas emissions, and high utilization of building materials [1][2][3]. As a type of enclosure system of prefabricated buildings, autoclaved lightweight concrete (ALC or AAC) panels are made of several fine aggregates (cement, sand, gypsum, aluminum powder, etc.)…”
