“…This is produced by activating ground-granulated blast-furnace slag (GGBS) with alkaline solutions, such as sodium silicate and sodium hydroxide. ASC has good mechanical behaviors [ 8 ] and durability [ 9 ]. Meanwhile, there is a limited understanding of the corrosion resistance of reinforced ASC due to a lack of data.…”

Alkali-activated slag concrete (ASC) is regarded as one of the most promising sustainable construction materials for replacing ordinary Portland cement concrete (OPC) due to its comparable strength and outstanding durability in challenging environments. In this study, the corrosion of steel bars embedded in ASC and OPC was studied by means of an electrically accelerated corrosion test of steel bars in concrete. Meanwhile, the bond performance of the corroded steel bars embedded in ASC was tested and compared with corresponding OPC groups. The results showed that ASC and OPC behaved differently in terms of bond deterioration. The high chemical resistance of ASC decreased the corrosion of steel bars and, thus, increased the residue bond strength and the bond stiffness.

“…The reduction in CO 2 emissions into the atmosphere has become a subject of great importance in recent decades in order to reduce the greenhouse effect [ 1 ]. Among the various types of industries, the cement sector is one of the largest contributors to CO 2 , estimated at around 8% of total anthropogenic greenhouse gas (GHG) emissions [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. One of the ways to reduce this impact is to reduce cement consumption by partially replacing it with supplementary cementitious materials (SCMs), which can be by-products from industry or natural pozzolans (NP), such as fly ash (FA), ground granulated blast furnace slag (GGBS), silica fume (SF), metakaolin (MK), limestone (L), fine glass powder (GP), rice husk ash (RHA), and volcanic tuffs (natural pozzolans) [ 5 , 6 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ].…”

“…Indeed, the abundance of these materials in certain geographic areas, such as volcanic regions, makes them attractive candidates as a partial substitute for cement, mortar, and concrete [ 1 , 10 , 21 , 22 , 23 , 24 , 25 ]. These materials are often disposed of in landfills, thus constituting a major environmental problem [ 5 ]. Therefore, its reuse would reduce the environmental impact, apart from CO 2 emissions, the reduction in the cost of concrete manufacturing, and the improvement of mechanical properties [ 17 ].…”

“…The effect of pozzolan additions to mortars and concretes varies depending on the type of pozzolan and the percentage of cement or aggregate substituted, among other factors. Generally speaking, pozzolan additions have been reported to increase durability [ 5 , 13 , 14 , 15 , 21 , 26 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ], decrease the heat of hydration [ 1 , 38 ], increase resistance to sulfate attack [ 1 , 39 ], increase setting time, prevent water penetration [ 1 , 40 ], and reduce energy cost per unit of cement [ 37 ]. Specifically, the effect these additions have on mechanical strength depends on many factors, and conflicting results can often be found in the literature.…”

Durability of Reinforced Concrete with Additions of Natural Pozzolans of Volcanic Origin

In this work, the properties of concrete modified with dosages of natural pozzolans (NP) in substitution of cement or superfine aggregates were evaluated. Proportions of 20/80 pozzolan/cement or pozzolan/superfine aggregates were selected for the additions of quarry and tuff pozzolans. Pozzolanic activity, durability, compressive strength, characteristic resistance, settling consistency, density, electrical resistivity, depth of water penetration, accessible porosity, and carbonation and chloride penetration were determined for the resulting concrete mixtures, and they were subsequently compared to the values obtained for the reference concrete batches without additions. The results of the cementitious mixtures supplemented with tuff (PZT) and quarry (PZQ) pozzolans, expressed in mmol/L, are consistent with the pozzolanism test, with [Ca(OH)2]/[OH−] ratios at 7 days are 6.03/60.19 for PZQ and 1.78/92.78 PZT. In addition to the pozzolanic activity at these dosages, the characteristic resistance and durability parameters required by EHE-08 were verified. Particular attention was given to the determination of the diffusion of chloride ions, introducing an instrumental modification of the accelerated integral method. The modification provides values of diffusion coefficients similar to those obtained by the other methods with the advantage of greater stability and quality of the measurement.

“…Glass is a material composed mainly of amorphous silica and present pozzolanic properties when finely ground [7]- [9]. According to Patel et al [15], glass particles up to 75 μm can replace Portland cement in amounts from 10% to 25%, showing satisfactory results in the production of cementitious composites, and several authors attributes improvements in mechanical properties to pozzolanic reactions from glass powder [3]- [12].…”

Novel developments on concrete technology such as high and ultra-high-performance concrete (HPC and UHPC) are notorious by its high consumption of Portland cement. Supplementary cementitious materials have been used as partial replacement of Portland cement aiming to minimizing clinker content, optimizing the use of binders, reducing CO2 emissions, and increasing durability. Waste glass powder could be an alternative due to its silica-rich nature and wide availability. This work aims to assess the influence Portland cement substitution by finely ground waste glass powder in contents of 10%, 20%, 30% and 50% on physical and mechanical behavior of ultra-high-performance cementitious composites (UHPCC). Results indicates the use of glass powder as substitution up to 50% of Portland cement does not significantly affect the analyzed properties at 28 days.
