“…With the advancement of cement science and technology and due to the necessity for slender and bolder structures, conventional concrete (CC), also named as normal strength concrete [ 1 ], no longer meets the requirements for the execution of these works. In this context, other concretes and other cementitious mixtures, with properties superior to CC, emerged to meet this need.…”

“…In this context, other concretes and other cementitious mixtures, with properties superior to CC, emerged to meet this need. This is the case for high-strength concrete (HSC) [ 2 ], high-performance concrete (HPC) [ 1 , 3 ] and, more recently, ultra-high performance concrete (UHPC) [ 3 , 4 ].…”

“…While the definition of HSC is based only on compressive strength, the definition of HPC and UHPC is related to performance, which includes not only mechanical strength but also workability, aesthetics, finish, integrity, and durability [ 12 , 13 ]. Despite not being unanimous, a satisfactory definition for the HPC is that this concrete presents a compressive strength equivalent to the HSC, that is, f ck above 50 or 55 MPa [ 2 , 14 ], but presents a workability equivalent to self-compacting concrete (SCC), that is, a spread between 455 to 810 mm by the slump-flow test [ 1 , 15 , 16 ]. Regarding the water/binder factor (w/b), some authors suggest that this factor should be less than 0.40 [ 17 , 18 , 19 ], contrary to what is observed in conventional concretes, where the w/b factor ranges from 0.45 to 0.65 [ 20 , 21 , 22 ].…”

This review article proposes the identification and basic concepts of materials that might be used for the production of high-performance concrete (HPC) and ultra-high-performance concrete (UHPC). Although other reviews have addressed this topic, the present work differs by presenting relevant aspects on possible materials applied in the production of HPC and UHPC. The main innovation of this review article is to identify the perspectives for new materials that can be considered in the production of novel special concretes. After consulting different bibliographic databases, some information related to ordinary Portland cement (OPC), mineral additions, aggregates, and chemical additives used for the production of HPC and UHPC were highlighted. Relevant information on the application of synthetic and natural fibers is also highlighted in association with a cement matrix of HPC and UHPC, forming composites with properties superior to conventional concrete used in civil construction. The article also presents some relevant characteristics for the application of HPC and UHPC produced with alkali-activated cement, an alternative binder to OPC produced through the reaction between two essential components: precursors and activators. Some information about the main types of precursors, subdivided into materials rich in aluminosilicates and rich in calcium, were also highlighted. Finally, suggestions for future work related to the application of HPC and UHPC are highlighted, guiding future research on this topic.

“…Studies conducted by Afshinnia and Rangaraju (2015) showed satisfactory results in mitigating the alkali-silica reaction when glass powder was used as a pozzolanic material in partial replacement to cement. High and ultra-high-performance concretes should solve the durability problem on chloride attack in ordinary structural concrete due to their dense microstructure (Sohail et al, 2021). The European Union generated about 25.8 Mt of glass waste in 2007 (Abdollahnejad et al, 2017).…”

O pó de vidro incorporado ao concreto convencional vem sendo estudado em relação à sua influência na resistência mecânica e durabilidade. Este trabalho visa avaliar a durabilidade de compósitos cimentícios de ultra alto desempenho (CCUAD) com substituição parcial do cimento por vidro finamente moído, por meio do ensaio de migração de cloretos utilizando o método da NT Build 492. Para tanto foram moldados corpos de prova com teores de pó de vidro de 0%, 10%, 20%, 30% e 50% em relação ao volume de cimento e a avaliação foi feita na idade de 28 dias. Os resultados indicam que, em teores baixos, o pó de vidro não prejudica as propriedades dos compósitos e em teores mais altos os compósitos mantêm boas características mecânicas e de durabilidade.

“…In a higher class of strength and durability, RPC was created by Richard & Cheyrezy (1995), classified among the ultra-high-performance concretes based on Portland cement that has the best physical and mechanical properties patented to date, used in same applications as conventional concrete or as auxiliary technology. The minimum threshold for compressive strength comprises values of the order of 120 MPa (Dixit, Du & Pang, 2020), however, in most studies, 150 MPa is adopted at 28 days of age (Kang, Hong & Moon, 2019;Liu, Wei, Zou, Zhou & Jian, 2020;Sohail, Kahraman, Nuaimi, Gencturk & Alnahhal, 2021).…”

Portland cement concrete manufacturing techniques in the world have an immense variability, since each location concentrates natural resources with unique characteristics, sometimes similar, but with always different process conditions, such as: labor, equipment, environmental conditions, processing, storage, among others. The aim of this work is to develop cementitious composites partially replacing mineral admixtures by powdered glass residues, evaluating the physical-mechanical behavior through axial compression strength, as well as the production of hydrated phases through x-ray diffraction, both at 28 days. Cement, silica fume, metakaolin, powder glass residue, polycarboxylic ether-based superplasticizer, and low temperature water were used to prepare different compositions of ultra-high performance concrete. The preparation took place with the aid of a mechanical bench mixer, and the densification was carried out with the aid of an immersion vibrator in cylindrical molds 50 x 100 mm. After unshaped, the specimens received heat treatment, with isotherm at 60°C for 36 hours, followed by wet curing in a tank saturated with calcium hydroxide, until the tests of compression strength and x-ray diffraction were carried out. The results show that the composition added with the residue, replacing metakaolin, behaved in an adequate manner, with compressive strength equivalent to the reference composition (silica fume + metakaolin), as well as the production of the same hydrated compounds. However, the application of only the glass residue or metakaolin reduced the intensity of the pozzolanic reactions, justified by the presence of a high content of calcium hydroxide in the compositions, which allows us to conclude that the powder glass residue presents viability as a filler, when replacing metakaolin in the presence of silica fume, as it does not compromise the performance of the mixtures made.
