Concrete mix ratio for floor. As we know that floor is non RCC structure so we can use minimum grade of M7.5 grade and concrete mix ratio 1:4:8 for floor & grade of concrete m10 & M15 are also used for floor. 1:4:8 (m7.5), 1:3:6 (m10) and 1:2:5 (m15) is concrete mix ratio used for floor, PCC & none RCC structure.

Types of Concrete Mix Ratio Design and their Strengths

Nominal mix ratios for concrete are 1:2:4 for M15, 1:1.5:3 for M20 etc. Standard Mixes or Ratio. The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under or over-rich mixes.

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio.
