What is C50 grade concrete?
A C50 concrete is used when placing concrete in harsh conditions where aggressive chemicals or high levels of abrasion are present, and you need a high-performance concrete that can provide the levels of durability and technical performance your specialist application requires.
What is C50 concrete mix ratio?
Table 3 shows the mixing proportion of concrete with a strength grade of 30 MPa and 50 MPa (C30 and C50) according to Chinese Standard. The cement ratio to fly ash or granulated blast furnace slag was 1:1.33. …
What does C40 50 concrete mean?
C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube. Therefore using the method of testing using concrete cubes, the tested compressive strength should be compared to the second number.
What is C60 concrete used for?
(5) C50 – C60: used for 30 – 60 layers high rise building; (6) C60 – C80: used in high-rise building, adopt high performance concrete; (7) C80 – C120: adopt ultra high strength concrete in high-rise building.
What is G50 concrete?
The strength of G50 increases 18% in sealed curing and site cured concrete has 8% strength increments from 28-90 day of age. Concrete G40 has the highest water absorption, VPV and sorptivity properties followed by G45 and G50 in all ages of test under both curing conditions.
