“…On other hand the use of hot curing around 100°C leads to having mixes with lower density (from 1.4g/cm 3 to 1.1g/cm 3 ) and higher compressive strength (from 3MPa to 5MPa). These results can be the second step on this research and the use of other binders, like the lime, can lead to a higher compressive strength with the use of steam or heat curing, this was confirmed by other researcher [26].…”

“…The increase of fawakher to cement ratio decreases the compressive strength due to the weaker fawkher aggregates. The increase of the GP replacement leads to an increase in the compressive strength, it supposes that the immersion of GP particles in the water leads to having more free ions SiO2, CaO and Na2O and higher compressive strength by the conversion of CH to CSH [18,[26][27][28].

This paper discusses the use of two different aggregates on the production of concrete blocks in construction. The use of aggregate type 1 showed a significant decrease on the compressive strength with 40% replacement of natural aggregates. The use of aggregate type 2, where the natural aggregate was totally replaced showed better results in term of compressive strength. At aggregate to cement ration equal to 4, the concrete has an acceptable density equal 1.4 g/cm3 and compressive strength equal 2MPa. The use of glass powder increases the compressive strength of these blocks to value higher than 3.5MPa and density around 1.3 g/cm3 which is acceptable according to the ASTM for masonry block to be used in construction.

“…Bisht and Ramana [118] recorded increases to water absorption, water permeability, and sorptivity when incorporating glass aggregates into concrete as a fine aggregate substitute. Water absorption and IRA may increase with glass powder content [60,119] followed by a reduction at higher dosages [110]. A reverse trend has been found by other authors [120][121][122][123][124][125].…”

Current Sustainable Trends of Using Waste Materials in Concrete—A Decade Review

et al. 2020

View full text Add to dashboard Cite

Concrete is the most used construction material in the world. Consequently, the mass extraction of virgin materials required for concrete production causes major environmental impacts. With a focus on promoting sustainability, numerous research studies on incorporating waste materials to replace virgin substances in concrete were undertaken. Despite this vast volume of published literature, systematic research studies on these sustainable concrete mixes that inform various stakeholders on current research trends, future research directions, and marketability options products are seldom conducted. This paper presents a decade review on sustainable concrete with a focus on virgin materials being replaced with waste materials. It aims to inform researchers of current research trends and gaps in the research area of waste material use in concrete. The review also identifies key parameters that restrict the marketability of these sustainable concrete products. The three-step research methodology involves a bibliometric assessment, a key review of selected waste materials, and an interview with a panel of experts focusing on impediments towards the transition of sustainable concrete products into the industry market. Bibliometric assessment was based on 1465 research publications in which five key materials (plastic, glass, fly ash, slag) and construction and demolition waste were selected for the review. The interview was conducted with ten industry experts to discuss the industry limitations in the commercial establishment of materials. The review of existing knowledge and the findings on sustainable concrete presented in this paper provide directions for both research academics and industry stakeholders to systematically focus on sustainable concrete products that are market-ready.

“…At 91 days of ETC, the lowest reduction in strength of 4% was recorded by mix with 15% GP and at the same age ambient cured mix with 30% GP showed a strength reduction of only 13%. Mix with 50% GP did not show acceptable results as the earlier studies had shown that the pozzolanic reaction ceases beyond a replacement level of 30% due to absence of lime [35,40]. In such cases, the additional GP would be acting as an inert filler.…”

Cement production involves extensive energy absorption and emits huge quantities of CO2 in the atmosphere. The production rates are increasing annually to meet the ever increasing demand with increased energy absorption and CO2 emission. Hence, it is imperative to use materials which can replace use of cement to some extent. Conversely, waste glass is being dumped in the landfills. This practice is environmentally unsustainable since glass is nonbiodegradable. Recently it's revealed that glass when grinded to a particular fineness exhibits cementitious properties due to pozzolanic reaction. This paper investigates the fresh, mechanical and durability properties of concretes made with cement replaced by coarse glass powder (<150 µm) at various replacement levels and employing different curing conditions. The replacement levels employed were 0%, 15%, 30% and 50% by weight of cement, while the curing regimes followed were ambient, Elevated Temperature Curing (ETC) @ 40˚C and water. Scanning electron microscopy (SEM) and X-ray fluorescence (XRF) techniques were performed on cement and glass powder to investigate the microstructure and chemical composition of the materials. The initial findings show that 30% is the ideal replacement level as it exhibits quite comparable strengths, better workability and higher resistance to chloride ion penetration compared to the control mix.
