When groundwater or soils containing concentrations of sulfates come in contact with concrete, a reaction takes place that may be harmful to the concrete.
These materials have very low level of CO2 emissions, and γ-2CaO⋅SiO2 hardens concrete by reaction with CO2.
Autogenous volume deformation of MgO concrete with reaction time ranging between 50 s and 200 s tended to stabilize after approximate two years development with no retraction or drop-back, and it exhibited good relationship with long-term water absorption of aggregates while alternative method to accurately quantify the effective periclase in clinker should be explored.
Social rejection is measured by a Likert scale consisting of 5 items that is inspired by the social rejection subscale of Fife and Wright [ 34], and which indicates concrete negative reactions from the environment following mental health treatment.
Crushed glass has been used as aggregate replacement resulting in a poor bond and concrete exhibiting alkali silica reaction (ASR).
With a large share of infrastructure systems, aged bridges are facing an increasing risk of failures, due to the deterioration of structural members caused by corrosion, fatigue, cracks, concrete alkali-silica reaction, the rise of traffic load, etc.
To assess the profile of penetration of the CI through the concrete cover, the reactions with cement matrix and its influence on the transfer properties are experimentally analysed and numerically modelled.
When Comme des Garçons debuted a new fragrance called "Concrete" in July of 2017, reactions (like concrete!) were mixed.
Warned that disclosing the project's secrets was punishable by 10 years in prison or a $10,000 $$ today) fine, they saw enormous quantities of raw materials enter factories with nothing coming out, and monitored "dials and switches while behind thick concrete walls mysterious reactions took place" without knowing the purpose of their jobs.
To make this more concrete, consider the reactions in the (M,R) model.
