Concrete Mix Ratio | Concrete Ratio | Concrete Proportions
2. Standard Mix Concrete Ratio. Nominal admixtures of fixed cement-aggregate ratios (by volume) vary widely in strength and may result in more or less rich admixtures. For this reason, minimum compressive strength is included in many specifications. These mixtures are called standard mixtures.. IS 456-2000 designates concrete mixes in several grades as M10, M15, M20, M25, M30, M35, and M40.

crashing strength of concrete
In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.

Different Types of Concrete And Their Uses
1. Normal Strength Concrete. This concrete combines all the basic ingredients — concrete, sand and aggregate — using the 1:2:4 ratio. This produces normal strength concrete. It takes about 30 to 90 minutes to set, but this is dependent on the weather conditions at the concrete site and the cement’s properties.

Types of Concrete & Characteristics | Concrete Classification
Compressive strength of high strength concrete mix is usually greater than 6,000 pounds per square inch.. High strength concrete is made by lowering the water cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement, which might reduce the strength at the cement aggregate bond.
