VSI sand maker, also called VSI crusher, is the major machine for sand making plant.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
On the basis of domestic mills, fote raymond mill is produced. The raymond roller mill enjoys the features of high working efficiency, low energy consumption, small floor space and small cost.
As a famous Chinese sand dryer supplier and manufacturer, our company has manufactured a lot of advanced sand dryers with quite a reasonable drying machine price in the dryer market.

3 standard grade of concrete m25 grade the mix ratio is 112 1 cement 1 sand and 2 aggregate it is used as rcc reinforced cement concrete applicationuse it can be used in the construction of slabs beams columns footings etc m30 grade it is used as rcc reinforced cement concrete
From fig 1 of is 10262 2019 the free watercement ratio required for the target strength of 3160 n mm178 is 048 may be used for opc 43 grade curve for other than mortamph m aximum water cement ratio required for the target strength of 3600 n mm178as per mortamph requirement is 044 from figure 1 of is 102622019
M stands for mix the mix is concrete with designated cement sand and aggregate proportions and the amount that follows m after 28 days reflects the compressive strength of that n mm2 concrete mix for example its compressive strength after 28 days should be 20n mm2 for concrete mix grade m20
Water cement ratio means the ratio between the weight of water to the weight of cement used in concrete mix normally water cement ratio falls under 04 to 06 as per is code 10262 2009 for nominal mix m10 m15 m25 we all know that water cement ratio will directly affect the strength of concrete either it increases the strength if
Deviations for the concrete cubes made with grade 325 cement and grade 425 cement for all the mix ratios considered are presented in the second and third columns of table 2 from table 2 the 245mpa average strength of the 124 concrete cubes moulded with

For example if the concrete mix is of m20 grade then the compressive strength will be 20 mpa different types of concrete mix ratio m25 112 designed concrete mixratio

Jun 11 2020nbsp018332concrete with good quality improves its properties such as strength durability etc the design mix which is prepared from suitable ingredients in respective proportions itself improves the concrete properties the concrete mix prepared is tested using compressive strength machines tensile strength machines in the form of concrete cubes and cylinders hence recommended grade of concrete
Therefore an appropriate grade of concrete can be selected based on structural requirements nominal mixtures for concrete types such as m15 m20 m25 are generally used for smallscale construction large structures have high strength requirements and are therefore used for higher grades of concrete such as m30 and above the mixing
The basic requirements for the design of concrete mix ratio are 1 meet the strength grade of concrete design 2 meet the concrete peaceability 3 meet the durability of the use of concrete 4 meet the above conditions to save cement and reduce the cost of concrete the strength of concrete is divided into twelve grades such as c75 c10
