“…This is believed to be higher WA of both porous RGS and RA compared to natural aggregates has lead to higher loss of workability due to increased water demand which is in agreement with previous studies [19][20][21][22][23][24][25][26]. Concrete compressive and flexural strengths are of great importance as these properties are utilised to specify structural concrete members within design parameters.…”

“…Tu and Chen [17] investigated that RA with higher absorption capacity comparing to natural aggregates have a slight influence on the concrete workability. Limbachiya [18] and Taha [19] stated that use of recycled glass sand (RGS) reduced the workability of the concrete due to lack of fine proportion. Taha [19] also reported homogeneity of the concrete was reduced in the presence of RGS which could be attributed to sharp edges of RGS increased the friction forces in the concrete matrix and thus reduced the consistency.…”

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.

Estimation of strength, permeability and hydraulic diffusivity of pozzolana blended concrete through AbstractThe pozzolanic reactivity of waste glass powder was experimentally studied at cement replacement levels of 0, 15, 30, 45 and 60% by weight. Results revealed that the concrete compressive strength was not decreased by the cement substitution after 28 days because of the pozzolanic reaction between glass powders and cement hydration products, if the replacement is below 30%. Also, the resistance to chloride ion and water penetration continuously increases with increasing glass powder content up to 60% cement replacement. At 60% replacement level, the electrical resistivity and water penetration depth were reduced by 95% and 80%, respectively, while the compressive strength was maintained as 85%. These improvements in durability properties are due to the refined microstructures, particularly at the interfacial transition zone. Pore size distribution was measured to confirm the refinement in the capillary pores, which partially block the pathways for water and chloride ions. This study also demonstrates that high performance concrete (improved strength and impermeability against chloride and water) could be achieved by using glass powder as 15% additive, which contributes to the pozzolanic reaction instead of being inert fines for compact packing.

“…Crame, and Crus [1] found that glass aggregate is a satisfactory substitute for natural fine aggregate at replacement levels up to 20% of the total aggregate in concrete; Taha and Nounu [2] proposed that adding ground granulated blast-furnace slag, metakaolin, PGP, and lithium nitrate (LiNO3) can minimize the risk of the expansion of concrete through the substitution of recycled glass waste; M. M. Y. Ali and A. Arulrajah [3] indicated that potentially up to 30% of recycled crushed glass with particle size of less than 4.75 mm could be safely added to Class 3 recycled crushed concrete in pavement subbase applications.…”

The drainage consolidation method has been efficiently used to deal with soft ground improvement. Nowadays, it has been suggested to use a new sand soil which is a composite of sand and recycled glass waste. The permeability performance of glass-sand soil was explored to judge the feasibility of glass-sand soil backfilled in the drainage consolidation of sand-drained ground. For comparison purposes, different mix proportions of recycled glass waste, fineness modulus, and glass particle size were analyzed to certify the impact on the permeability coefficient and the degree of consolidation. The numerical results show that adding a proper amount of recycled glass waste could promote the permeability performance of glass-sand soil, and the glasssand soil drain could be consolidated more quickly than a sand drain. Experiments showed that glass-sand soil with the a 20% mix of recycled glass waste reveals the optimum performance of permeability.
