“…In parallel with this, it was also observed that SP demand required increased with the increased the replacement level of CMC in CEM II/B-M and CEM V/A mixes. This is in agreement with the previous studies [15,30,[33][34]50]. The effect of w/c on SP demand was more obvious for CEM V/A mixes compared to CEM II/B-M mixes.…”

“…Khatri [52] and Güneyisi [60] stated that inclusion of SF increases the fine pores in the matrix and thereby leads to water loss. This also supports previous studies [15,32,60] that the adverse affect of SF was diminished when it is blended with another CMC in concrete.…”

“…Another study by Limbachiya [14] revealed that FA concretes with higher binder content reduced the workability. Gesoglu [15] stated that the relationship between FA and workability loss could be attributed to the presence of FA when used in binary and ternary cements increased viscous characteristics of concretes. Erdem [16] also investigated that silica fume (SF) concretes may require more water as the SF increases due to SF has higher surface area, which this could be compensated by SP utilization.…”

Sustainable development approach demands the use of environmentally friendly materials. One possible way to encourage sustainable approach is via use of Portland cement (PC) replacement through use of permitted cement constituents in conformity with BS EN 197-1, to lower carbon footprint, and use of recycled aggregates as permitted within BS 8500, to encourage sustainability. Thus, this research study aimed to produce low carbon and sustainable concrete. For this aim, engineering and durability properties of equal 28-day design strength (40 and 50 N/mm 2 ) concretes made with Portland-composite and composite cements, CEM II/B-M and CEM V/A respectively, and partially substituted coarse recycled (RA) and washed recycled glass sand (RGS), 25% and 15% respectively, aggregates was investigated. The loss of workability was found to be larger for particularly CEM V/A and recyled aggregate concrete (RAC) mixes. Studies of hardened concrete properties, comprising bulk engineering properties (compressive cube and cylinder strength, flexural strength, drying shrinkage) and durability (initial surface absorption) showed enhanced performance for CEM II/B-M and CEM V/A mixes of equivalent strength natural aggregate concrete mixes (NAC), except resistance to carbonation. However, the use of CEM II/B-M and CEM V cements in RAC mixes slightly reduced the engineering and durability properties compared to corresponding NAC mixes.Keywords: Carbonation, initial surface absorption, drying shrinkage, fly ash, ground granulated blast-furnace slag, silica fume, recycled glass sand, coarse recycled aggregate Bullet points:Use of CEM II/B-M and CEM V/A cements and coarse recycled aggregates and recycled glass sand in concrete production increased the required superplasticizer demand to achieve the similar consistency.CEM II/B-M cement recycled aggregate concrete mixes indicated either similar or slightly better loss of workability over time compared to corresponding CEM I cement RAC mix.The partial substitution of natural coarse and fine aggregates by 25% coarse recycled and 15% recycled glass sand aggregates reduced the compressive cube strength of concrete approximately by 10%.Recycled aggregates concrete mixes showed dramatically lower compressive cylinder strength results compared to conventional natural aggregate concrete mixes.Drying shrinkage results showed that the contribution of pozzolanic reactions for Portlandslag and composites cement concretes takes place after 14 days.CEM II/B-M cement mixes indicated lower ISAT-10 values as the design strength class increased.Carbonation penetration results showed improvement as the design strength increased for the same cement type concrete mixes.

“…Studies carried out by Khatri [6] and Berndt [12] with 70% slag replacement in binary blend cement and 65% GGBS with silica fume (SF) in ternary blend cement concretes respectively indicated improved compressive strength at longer ages. Gesoğlu [14] stated that use of GGBS in ternary blend cement concrete with another mineral admixture fly ash (FA) with replacement levels of 10% for both admixtures provided the best performance strength at 28 days. Güneyisi [8] also studied GGBS in ternary blend with SF and FA and stated comparable or improved results monitored for GGBS + SF blend cement concretes regardless the increase in the replacement level (15% GGBS + 5% SF, 30% GGBS + 10% SF, 45% GGBS + 15% SF).…”

The use of different cementitious main constituents is permitted within the BS EN 197-1 for use in concrete construction. The selection of cement types made depends on requirement of enhanced engineering and durability properties of concrete as well as exploiting potential for producing environmentally friendly concretes for practical applications. The main results of a laboratory experimental programme aimed at examining the performance of Portland-slag and composite cement (CEM II/B-S, CEM II/B-M, CEM V/A and CEM V/B) concrete mixes designed for equivalent 28-day compressive cube strengths of 40 and 50 N/mm 2 are reported in paper. The effect of up to 30-50% of ground granulated blast-furnace slag (GGBS) and its' combination with the silica fume (SF) and fly ash (FA) -within the BS EN 197-1 permitted limits-on fresh, engineering and durability properties have been established and its suitability for use in a range of practical applications was assessed.The loss of workability in all mixes was of a uniform nature and was found to be more for CEM V/B concrete mixes. Studies of hardened concrete properties, comprising bulk engineering properties (compressive cube and cylinder strength, flexural strength, drying shrinkage) and durability (initial surface absorption, carbonation rates) showed enhanced performance for Portland-slag and composite cement concrete mixes of equivalent strength, except resistance to carbonation.Keywords: Carbonation, drying shrinkage, durability, fly ash, ground granulated blast-furnace slag, initial surface absorption, mechanical properties, Portland cement, silica fume Bullet points:Lower w/c ratios did not have any influence on minimizing the early strength loss for equivalent 28-day strength concretes.Drying shrinkage results showed that the contribution of pozzolanic reactions for Portlandslag and composites cement concretes takes place after 14 days.Portland-composite cement concretes (PC+GGBS+SF) with higher w/c ratio showed improved pore structure.Carbonation resistance was observed to be linked with the loss of workability over time.

The choice of blended cements and materials with cementitious properties in concrete is currently seen as a choice that increases the environmental sustainability of the construction industry. The developments with non‐traditional binders (such as the simultaneous incorporation of several types of supplementary cementitious materials) have highlighted new challenges to be researched. In the present paper ternary binders were prepared by mixing ordinary Portland cement (OPC) plus two blended components: low calcium fly ash, blast furnace slag, and/or limestone filler. Several physical and mechanical properties of ternary blend systems have been analyzed in mortar form at several curing ages: 2, 7, 28, and 90 days. Additionally preliminary tests of corrosion performance of reinforcement in these types of mixes have been considered. The results indicate that the use of appropriate content components in ternary blends will allow binders to fulfill the specified mechanical requirements. The best results are obtained when two additions with antagonist properties are mixed, as fly ashes and slags or slags and filler limestone. Besides, certain influence of the effect on durability performance is detected, in particular associated with the stability of the passive state and corrosion of reinforcements in presence of chlorides.
