Impact of Glass on Concrete Properties as Substitution of Aggregate

Abstract

The improvement of mixture quality has been the priority of the modern-day construction industry while reducing the financial implications of the final product. This investigation concentrated on the application of glass as fine aggregate in the production of concrete. The fine aggregates used were partially substituted with fine glass. The replacement was done at (0, 10, 20, 30, 40, and 50%) by weight of fine aggregates, with other materials constant. A concrete mixture was prepared and the slump flow test and density were examined. The concrete specimens were produced, cured, and compressive, flexural, and splitting tensile intensity tested at 7, 14, and 28 durations. The workability and density of concrete reduce as the percentage replacement increases and the maximum reduction are (25 and 6.5%) respectively for (50%) glass aggregate replacement. The highest development in concrete compressive strength, flexural and splitting tensile intensity is (16.4, 14.7, and 15.1%) for 28 days of the glass aggregate percentage (20%) and the highest decrease is (3.4, 3.1, and 3.6%) for the percentage (50%).

Rheological and Mechanical Characterization of Self-Compacting Concrete using Recycled Aggregate

“…This finding was confirmed by Ali and Al-Tersawy [36] when explored replacing fine aggregate with crushed glass only. Likely, Jassam et al [40] observed that at the RG content increase as fine aggregate replacement the slump of the traditional normal concrete decreases, but it must be noted that the utilization was in normal concrete not SCC. The results showed that slump flow got higher and increased as the fine aggregate replacement with CRG increased although the increase of binder powder by 50 kg/m 3 or a constant 10% of SF [37].…”

Studying the usability of recycled aggregate to produce new concrete

“…The quality of the recycled aggregate is vital in determining the strength of the mixture. This feature is determined by many elements, including the age of the original concrete, the recycling technology used, the grade of crushed concrete utilized for the recycled aggregate, and the meticulous consideration of all aspects in formulating and preparing the concrete mixture for this particular composition [12][13][14]. So far, among the technologies developed for the recycling of concrete waste, the use of a crushing machine to reduce the waste into particles of recycled aggregates is currently widely used to produce recycled aggregates.…”
