Mix Design For M35 Grade Of Concrete - Civil Engineering
Jul 09, 2017 · MIX DESIGN. Take Sand content as percentage of total aggregates = 36%. Select Water Cement Ratio = 0.43 for concrete grade M35 (From Fig 2. of I.S. 10262- 1982) Select Water Content = 172 Kg (From IS: 10262 for 20 mm nominal size of aggregates Maximum Water Content = 186 Kg/ M 3) Hence, Cement Content= 172 / 0.43 = 400 Kg / M 3

What is the recommended value of the slump of M-30 grade
Answer (1 of 5): Slump Used to test the work-ability of the concrete. Which depends on mainly (yes, there is many factor but mainly) W/C ratio (Water to cement ratio). Higher the W/C ratio means higher the workability which means higher the slump value you get during the test. Side-effects of

Understanding Wet-Mix Shotcrete: Mix Design
Batching and mixing a high-quality and pumpable . wet-mix shotcrete is not always a simple task, particularly when high dosages of fibers are used. Using a classic mix design approach for conven-tional concrete may result in non-pumpable or difficult to pump concretes. Adding fibers to ordinary wet-mix shotcrete can produce similar effects.

Here M is grade of mix ratio and numerical value 5, 10, 15, 20…etc are strength of concrete in KN/mm². So, if we have M20 grade concrete then we can say that its grade is 20KN/mm². And mix proportion is 1:1.5:3 which indicates that in this types of mix ratios 1 part is cement, 1:5 part is sand and 3 part is aggregate has been used to make
