Resumo:
Self-compacting concrete (SCC) is an innovative type of concrete that does not require vibration
for compaction, being considered in the field of civil construction one of the great innovations
of the sector in the last decades. In large concrete works, such as dams and hydroelectric plants,
one of the problems is in the control of thermal cracking, due to the heat of hydration that
originates mainly during the concrete curing process. Among the alternatives to mitigate
pathological manifestations are superabsorbent polymers (SAP) that show promise in the field
of engineering when added to cementitious composites. This work aims to analyze the addition
of SAP as an internal curing element in self-compacting mortars (AAA), as well as its
mechanical and thermal characteristics, in order to obtain an ideal proportion of the materials,
so that it serves as a basis for execution. of self-compacting concrete, with a focus on structures
with large volumes. In addition, this work presents a bibliometric analysis in the Scopus and
Web of Science databases on the same topic, in order to facilitate the location of relevant studies
for future research in this area. In this analysis, data on the number of publications, main authors
and journals, most used keywords and countries that publish the most were obtained, in addition
to bibliographic coupling and co-citation analyses. In the experimental program, laboratory tests
were performed with AAAs with 0; 0.1 and 0.2% addition of SAP for both CPII-E-32 and CPV ARI and part of the samples underwent a submerged cure, while another part underwent a dry
cure. Among the results obtained in the laboratory, the reduction of temperature variation of the
traces with the addition of SAP stands out, where it is possible to assume a possible way of
mitigating the temperature peaks in concrete pieces with large volumes. On the other hand, the
compression and traction tests indicated loss of strength of the mortars, with the exception of
the traction test carried out for CPII-E-32, where an increase in strength was obtained with the
incorporation of SAP in the mixture.
