“…It was found that compressive strength is maximum when manufactured sand is used in concrete containing GGBFS. Abrasion resistance was influenced by strength irrespective of GGBFS and manufactured sand content [30]. The consistency of cement decreases with increases in GGBFS amount while workability and setting time increases.…”

The present studies focus on the characteristics of binary and ternary concrete in plastic and hardened stage for a mix of grade M25. Two mineral admixtures were used, sugarcane bagasse ash (SCBA) and ground granulated blast furnace slag (GGBFS). In preparing binary and ternary blended concrete, these admixtures partially substituted cement. Cement was replaced with SCBA and GGBFS, with the substitution percentage being 15%, 20%, 25%, and 30% by mass. Fresh properties were evaluated in terms of slump cone and setting time. Moreover, the mechanical characteristics were assessed concerning the strength of concrete in compression, split, and flexure. The microstructural properties were investigated in terms of scanning electron microscope (SEM) images. The experimental result indicated that the inclusion of SCBA and GGBFS improves workability and strength in compression while strength in the split and flexural hampered in binary as well as ternary concrete.

Roller compacted concrete is a type of zero slump product produced from the same materials with conventional concrete. There are various methods for the design of RCC namely; corps of engineers’ practice, high paste method, roller compacted dam method and maximum density method. Development of RCC has led a significant shift in the construction projects primarily in dams as the traditional practise of placing, compacting and consolidation is slow. By using RCC in earth and rock filled dams made the construction process quicker and consequently shortened the duration of construction. RCC used dam projects and be completed 1-2 years earlier than the other dams as mentioned in the article of Bagheri and Ghaemian (2004). Use of RCC has substantially increased in the last decades especially for pavement applications. It has a low construction cost and can be done quickly compared to asphalt. It is widely constructed in areas/ roads carrying heavy loads in low speed. On the other hand, in recent years' utilization of RCC in urban areas such as highways and streets has also increased. It has been proved that RCC has a competitive advantage over high performance asphalt pavements in terms of high compressive strength, durability, low maintenance cost, longer service life. Like conventional concrete, fibre addition is widely preferred in RCC as well. Fibre addition has contribution to mechanical properties of RCC and sustainability.

“…RCC is a strong material with unique properties that can preserve the stability of heavy-duty and mass concreting operations in structures and infrastructures. In general, RCC is a zeroslump concrete in its fresh state (ACI, 2011;Rao et al, 2016aRao et al, , 2016b, handled by vibrating drums and rollers (Chhorn et al, 2018). It has the same components of conventional concrete (CC) (Courard et al, 2010), and its importance comes from the ability to provide a similar strength as CC (Harrington et al, 2010;Kokubu et al, 1996) with good durability and low maintenance requirements (Mohammed, 2018) at a significantly reduced cost (Courard et al, 2010;Nagayama & Jikan, 2003;Warren, 2013).…”

There is no doubt that concrete is one of the most consumed materials all over the world. It is a composite mix widely used for constructing structures and infrastructures to sustain environmentally induced stresses such as thermal and seismic. As the mainstream of construction industry is tended to find out feasible solutions, Roller Compacted Concrete (RCC) was introduced to play an essential role in the development of dams and pavements, where over 550 RCC dams were created by the end of 2012. In fact, this material has the same basic constituents of conventional concrete with a zero-slump and a significant difference in the placing process. The majority of available studies in the literature are composed of numerical investigations to assess the thermal and seismic behavior of RCC dams and to provide a clear view on how to improve its performance under various loading conditions. This paper summarizes and compares the general conclusions of recent works on evaluating the structural performance of RCC dams.
