specializing in the production of large, medium and small concrete mixers, concrete mixing stations, stabilized soil mixing stations and other equipment. It is a heavy industry enterprise integrating R & production and sales.
May 17, 2017 Concrete Mix design of M5, M7.5, M10, M15, M20, M25, M30 and higher grades of concrete is calculated as below: The procedure for finding the different grades of concrete mixes are same. The below mentioned method can be applied to any grade of concrete by changing the values.

Apr 01, 2018 Lean concrete is a mix where the amount of cement is lower than the amount of liquid present in the strata. The higher the Aggregate/cement ratio, the leaner the concrete. In lean concrete, less quantity of paste is available for providing lubrication, per unit surface of aggregate and hence the mobility of aggregate is restricted

The strength is measured with concrete cube or cylinders by civil engineers at construction site. Cube or cylinders are made during casting of structural member and after hardening it is cured for 28 days. Then compressive strength test is conducted to find the strength. Regular grades of concrete are M15, M20, M25 etc.

Proper calculation and relative proportioning of materials are important to produce a good quality concrete. Let’s see some simple techniques used by engineers to calculate cement, sand, coarse aggregate (gravel or Jalli) and water needed to produce different grades of concrete, like M5, M7.5, M10, M15 and M20.

In this article we are discussing about concrete mix ratio and ideal mix concrete. Making concrete, it is important to use the correct concrete mixing ratios to produce a tough, long life, durable concrete mix. To make concrete, four basic materials you need: Cement, sand, aggregate, water, and add-mixture.

Compression test is required almost in every project since it gives us a brief idea of the grade and type of concrete. Many of them do small mistakes in these which includes the different exclusion of different parameters of concrete, improper procedure for filling and compacting concrete, wrong methods of testing of concrete and many more.
