Both the capacitances of the alkali-activated concretes are found to be lower than those of the conventional concretes, potentially attributable to the differences in the stoichiometry of the reaction products and the surface charge in the solid products primarily being influenced by the alkalis sorbed on the reaction products in the activated slag pastes.
Calera calculates that producing a ton of these minerals consumes half a ton of CO2, so the resulting concrete could potentially be carbon negative — sequestering carbon dioxide permanently.
Unlike more symbolic actions being discussed in Washington, like throwing Russia out of the Group of 8 industrialized nations, canceling the nuclear pact would involve concrete consequences potentially worth billions of dollars to Russia.
The model may be useful for engineering concrete for potentially at-risk elements.
The behavior of GFRP reinforcement, after high temperature exposure, is of critical importance for applications in concrete structures potentially subjected to fire.
Among the three aggregates considered here, quartzite exhibits the highest linear thermal expansion coefficient, therefore, the quartzite concrete has potentially yielded a higher volume expansion than limestone and granite concretes.
Due to the low temperature sensitivity of volume change of calcite, limestone and limestone concrete have potentially shown the lowest thermal expansion among the three aggregates and concretes, respectively.
Direct tests of genetic adaptation are very effective in establishing a concrete, and potentially deleterious population-level effect of contaminant exposure, but they are difficult to accomplish with most field-exposed organisms.
Topographic differences were observed within the FN400 latency interval, especially over anterior-inferior electrodes, with the repetition effect more pronounced and localized over the left hemisphere for concrete stimuli, potentially reflecting different neural processes underlying early processing of verbal/semantic and visual material in memory.
Thus, protecting the concrete surface can potentially enhance its durability to salt weathering.
