Carbonation of concrete with construction and demolition waste based recycled aggregates and cement with recycled content [PDF]
Durability is a major concern in concrete (particularly recycled concrete) structures exposed to carbonation-induced corrosion, given the social, economic, environmental and safety implications involved.

Abstract Fiber addition is a common strategy to enhance concrete's durability, avoiding cracks and reducing penetration of harmful agents. In this research, a sustainable fiber‐like material obtained from mechanical recycling of dismantled wind‐turbine blades and made up of glass fiber‐reinforced polymer (GFRP) fibers and microfibers, balsa wood, and ...

Concrete Pavement Mixture Design and Analysis (MDA): Evaluation of Foam Drainage Test to Measure Air Void Stability in Concrete [PDF]
The stability of air bubbles in fresh concrete can have a profound influence of the potential durability of the system, because excessive losses during placement and consolidation can compromise the ability of the mixture to resist freezing and thawing ...

Structure and mineral composition of soil-cement with complex additive
The effect of the polycarboxylate ether and the complex hydrophobic-plasticizing additive on the structure, phase and mineral composition of cement based on polymineral clay with content of relict minerals more than 85 % (52.49 % of quartz) was studied ...

Experimental data of cement grouting in coarse soils with different superplasticisers
High-range water reducers, such as superplasticisers, can be potentially viable for cement grouting applications. In this study, we investigate the influence of two types of superplasticisers—one based on polycarboxylate ether and another based on ...

Internal curing of cement pastes by superabsorbent polymers studied by means of neutron radiography [PDF]
Autogenous shrinkage is a problem in cementitious materials with a low water-to-binder ratio. When the internal relative humidity decreases due to the ongoing hydration reaction and selfdesiccation, autogenous shrinkage takes place if no external or ...

Clays for Low‐Carbon Cements: Overview, Progress, and Challenges
This review provides a critical overview of recent developments of activated clays to function as artificial pozzolans. After a thorough description of the clays that yield good pozzolanic performances, selected examples are given on thermal and mechanical activations. Chiefly, general correlations are extracted from reported data despite its scattered

Effect of sodium hexametaphosphate and trisodium phosphate on dispersion of polycarboxylate superplasticizer [PDF]
The high fluidity cement-based material has been widely used in indoor floor, grout, pumping concrete and self-compacting concrete. Efficiently dispersing the cement grains is essential for the practical application of this kind of material. Generally,

Interaction between cements with different composition and superplasticizers
The slump behavior of ordinary Portland-, pozzolanic (red brick powder)-, sulfate resistant-, and limestone cement pastes caused by ≤ 1% additions of polycondensates and polycarboxylates superplasticizers are monitored for up to 90 minutes.
