While traditional concrete normally has a compressive strength ranging anywhere from 2,500 to 5,000 psi, UHPC can have a compressive strength of up to 10 times that of traditional concrete. After just 14 days of curing, UHPC has a compressive strength of 20,000 psi. This number increases to 30,000 psi when fully cured for 28 days.

Roller-compacted concrete (RCC) is typically used in the construction of dams and road pavements since it provides substantial benefits over conventional concrete for the construction of such structures such as faster construction, lower costs of construction and materials, etc. Incorporating fly ash into RCC can further reduce cost of materials and enhance the concrete performances.

compressive strength of concrete mixes made with various % of Washed Bottom Ash as fine aggregate replacement. The compressive strength of control sample (fully natural sand) was determined at 3, 7, 28, and 60 days of curing. It was seen that the compressive strength of concrete mixes of sand replacement is much lower than control sample at
