Micro-milling is the removal of a small thickness (1 inch or less) of existing asphalt concrete prior to placing a surface treatment. The difference between cold milling and micro-milling is the texture left on the existing pavement. Micro-milling provides for a smoother surface than cold milling and is typically used before a slurry seal or ...

The mix proportions ratio of concrete details the proportion of cement, sand and water it needs to make that particular strength of concrete. For example M20 grade of concrete is the mix ratio 1:1.5:3. The "1" is cement, "1.5" is fine aggregate and "3" is coarse aggregate. This mix applies to all grades of concrete.

Concrete Grade As Per Indian Standards. The "M" refers to Mix and Number after M (M10, M20) Indicating the compressive strength of concrete after 28 days of curing and testing. M indicates the proportion of materials like Cement: Sand: Aggregate (1:2:4) or Cement: Fine Aggregate: Coarse Aggregate.
At 0.25% volume of HSF, low strength C20 concrete showed higher residual strength and flexural toughness than that of the plain high strength C45 concrete. The analysis of design thickness of pavements revealed that low-strength C20 at 0.25–0.5% HSF can provide cost-effective and eco-friendly pavements compared to a plain high …
M indicates the proportion of materials like Cement: Sand: Aggregate (1:2:4) or Cement: Fine Aggregate: Coarse Aggregate.
