concrete c35 - 1:1,5:2,5 (cement,sand,aggregate)
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
The compressive strength of M25 concrete at 7 days will be between 6-7.5 N/mm2 .
The strength of concrete on the 28th day is considered full strength with regard to the engineering calculations for its use. Concrete continues to get hard for 100 years or more, as long as it has water on it now and then. For a 6-sack concrete mix, its 28 day compressive strength should be at 4,000 psi or greater.

The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
The ideal cement and sand mix ratio for optimal strength in a concrete mixture is typically 1 part cement to 3 parts sand. This ratio helps ensure a strong and durable concrete mix.
To create a strong concrete mix for building projects, it is important to use the right proportions of cement, aggregates, and water. Properly mixing and curing the concrete, as well as adding additives like plasticizers or air-entraining agents, can also improve its strength and durability. Testing the mix for consistency and strength before use is essential for ensuring a successful construction project.
Its the process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
To create a durable and strong concrete structure using a concrete sand mix, it is important to follow these best practices: Use the right proportions of concrete, sand, and water as specified in the mix design. Ensure thorough mixing of the ingredients to achieve a uniform consistency. Properly compact the concrete to remove air voids and improve strength. Cure the concrete properly by keeping it moist and at the right temperature for an adequate period of time. Consider adding reinforcing materials like rebar for added strength and durability.
The best concrete for crafts is typically a fine-grained, high-strength concrete mix that is easy to work with and provides a smooth finish. Look for a mix specifically designed for crafting projects, as it will have the right balance of strength and workability for your needs.
it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....
The concrete mix should be a 5:1 Cement to water ratio. make sure you mix thoroughly when adding water. Look up "Concrete slump test"
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
It is not recommended to mix chalk with concrete as chalk is not a suitable additive for concrete. Chalk is primarily composed of calcium carbonate, which can affect the overall strength and durability of concrete when mixed in. It is best to use materials that are specifically designed for concrete mixes.
does not exceed 30N/mm2
