“…Partial replacement of OPC with a combination of glass powder (GP) and GGBS may enhance the durability of concrete by decreasing water absorption as measured by the sorptivity test. It was demonstrated that a partial replacement of 50% OPC with a combination of 15% glass powder (GP) and 35% GGPS decreased water absorption of concrete [8]. Under an elevated temperature as high as 700 • C, a loss in compressive strength and mass in concrete made with 100% OPC was comparable to concrete made with up to 50% GGBS [9].…”

“…Dadsetan and Bai [12] tested 100 mm cubes SCC samples (w/b = 0.45) in which OPC was partially replaced with 10%, 20%, and 30% GGBS, and demonstrated that the compressive strength increased with replacement ratio and surpassed the control mix. In a concrete strength/durability study where 50% of OPC was partially replaced with various combinations of glass power (GP) (45% to 5% in decrements of 5%) and GGBS (5% to 45% in increments of 5%), the optimum GGBS replacement for maximum compressive strength was found to be 35% (along with 15% GP) after 3, 7, and 28 days of curing [8]. It is important to note that the 35% optimum GGBS replacement ratio occurred in studies using 150 mm concrete cubes.…”

The production of cement requires significant energy and is responsible for more than 5% of global CO2 emissions; therefore it is imperative to reduce the production and use of ordinary portland cement (OPC). This paper examines the compressive strength development of low water-to-binder (w/b) ratio self-consolidating concrete (SCC) in which 90% of the cement is replaced with industrial by-products including ground granulated blast furnace slag (GGBS), fly ash, and silica fume. The emphasis in this paper is on replacing a large volume of cement with GGBS, which represented 10% to 77.5% of the cement replaced. Fresh properties at w/b ratio of 0.27 were examined by estimating the visual stability index (VSI) and t50 time. The compressive strength was determined after 3, 7, 28, and 56 days of curing. The control mix made with 100% OPC developed compressive strength ranging from 55 MPa after three days of curing to 76.75 MPa after 56 days of curing. On average, sustainable SCC containing 10% OPC developed strength ranging from 31 MPa after three days of curing to 56.4 MPa after 56 days of curing. However, the relative percentages of fly ash, silica fume, and GGBS in the 90% binder affect the strength developed as well. In addition, this paper reports the effect of the curing method on the 28 day compressive strength of environmentally friendly SCC in which 90% of the cement is replaced by GGBS, silica fume, and fly ash. The highest compressive strength was achieved in samples that were cured for three days under water, then left to air-dry for 25 days, compared to samples cured using chemical compounds or samples continuously cured under water for 28 days. The study confirms that SCC with 10% OPC and 90% supplementary cementitious composites (GGBS, silica fume, fly ash) can achieve compressive strength sufficient for many practical applications by incorporating high amounts of GGBS. In addition, air-curing of samples in a relatively high temperature (after three days of water curing) produce a higher 28 day compressive strength compared to water curing for 28 days, or membrane curing.

“…Furthermore, replacing the cement with 80% of GGBS produced SCC mix with a 28-day compressive strength of 50.45 MPa, which is suitable for many structural engineering applications. Hydrated cement contains about 70% C-S-H and 20% Ca(OH) 2 in addition to other compounds [24]. The strength and durability of concrete is affected by the presence of Ca(OH) 2 , which is water soluble.…”

This study examines durability and mechanical properties of sustainable self-consolidating concrete (SCC) in which 80% of the cement is replaced with combinations of recycled industrial by-products including fly ash, silica fume, and ground granulated blast furnace slag (GGBS). The water to binder (w/b) ratio of SCC mixes studies was maintained at 0.36. The study proposes empirical relationships to predict 28-day compressive strengths based on the results of three-day and seven-day compressive strengths. In addition, the chloride penetration resistance of the various sustainable SCC mixes was determined after three days, seven days, and 28 days of moist curing of concrete standards. It was concluded that fly ash, silica fume, and GGBS contribute favorably to enhancing strength development, fresh properties, and durability of SCC in comparison to ordinary Portland cement (OPC). The compressive strength of the sustainable SCC mixes falls within ranges suitable for structural engineering applications. Replacing cement with 15% silica fume produced a 28-day average compressive strength of 95.3 MPa, which is 44.2% higher than the control mix. Replacing cement with 15% or 20% silica fume reduced the chloride ion permeability to very low amounts compared to high permeability in a control mix. replacement of cement in SCC mixes results in loss of concrete compressive strength during the early stages, but, in many cases, a significant increase in compressive strength develops during later stages.Adding 3.8% silica fume improves compressive strength, splitting, tensile strength, and durability of SCC mixes Quercia [5]. It was found that replacing 15% of cement by silica fume resulted in a 28-day compressive strength of 95.3 MPa, which was 44% higher than the control SCC mix examined in the study by Mohamed and Najm [6]. Due to their spherical morphology, which reduces inter-particle friction, both silica fume and fly ash enhance workability and is essential for producing high strength concrete.Partial replacement of cement in SCC with various industrial byproduct wastes such as limestone power, cement kiln dust, and pulverized steel slag improves resistance to chloride penetration [7]. Other studies, however, contend that, under laboratory conditions, the durability of SCC and traditional vibrated concrete may be comparable [8] and that using Rapid Chloride Penetration Test (RCPT) to assess durability of SCC does not produce reliable results. However, the same study acknowledges that the quality of compacting vibrated concrete onsite is unlikely to reach the quality of SCC. As a result, concrete structures built with SCC may still be more durable.Partial replacement of cement with GGBS in SCC enhances compressive strength and durability. In one study, it was shown that replacing 70% of cement in a particular SCC mix resulted in strength as high as the control SCC mix [9].Alkali-silica reaction (ASR) may lead to significant long-term damage and degradation of concrete properties [10]. GGBS is known to improve concrete resis...

“…Another proposed solution is the introduction of glass into concretes in the form of dust [13][14][15][16][17][18][19][20][21][22][23][24][25]. This type of additive also has a positive effect on cementitious composites.…”

The paper presents an analysis of the possibilities of using glass waste from recycled lighting materials as aggregates for cement concrete. The research material was obtained from a company that utilizes electrical waste. Glass from pre-sorted elements was transported to the laboratory and crushed in a drum crusher. In this way, the aggregate obtained was subjected to the basic tests that are carried out for aggregates traditionally used in construction. The specific density of aggregate, bulk density, absorbability, crushing index, grain shape, texture type and aggregate flatness index were examined. In the next stage of research work, concrete mixtures were made in which crushed aggregate from crushed fluorescent lamps was used as a substitute for gravel aggregate. Mixtures containing 10%, 30%, 50% and 100% aggregate were made. A mixture containing only sand and gravel aggregate was made as a comparative mixture. Basic tests of both fresh concrete mix and hardened concrete were carried out for all concrete made. The consistency of the fresh concrete mix, the air content in the concrete mix, the density of hardened concrete, absorbability, water permeability under pressure and the basic compressive and tensile (flexular) strength tests were performed. The test results showed that the greater the addition of recycled glass aggregate, the less advantageous are the features of the concrete obtained with its participation. Microscopic analyses carried out in order to explain this phenomenon indicated an unfavorable influence of the grain shape of the aggregate thus obtained. Despite this fact, recycling of lighting waste in concrete composites is recommended as a pro-ecology measure; however, attention was paid to the benefits of using only 30% by mass of said waste in relation to the weight of the traditional aggregate used. Composite with such a quantity of waste retained the characteristics of cement concrete, which qualified its use for construction concrete.
