Concrete Mix Ratio And Slump Value Of Concrete ...

Typically, a mix is about 10 to 15 % cement, 60 to 75 % aggregate and 15 to 20 % water. This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture. Type of Concrete Mix Ratio. As Per IS Code 456-2000 three different part of Concrete Mix Ratio

Test 1 : Standard Slump and Flow Table Tests

2004-2-10  1. The Kistner concrete mix achieved a high slump of nearly 9 inches, using a water -cement ratio (w/c) of 0.63. This is different from the 0.4 value actually used by Kistner, because they use wet aggregate in their manufacturing facilities. 2. The equivalent flow table test result for the same mix, but without the coarse aggregate, was 166 mm.

Concrete Mix Attributes, Instructions and Slumps

2019-3-19  Workability: The concrete mix workability is the property that determines the mix capacity to be placed and consolidate properly, allowing to finish a product without segregation. Consistency: This property determines the mobility and slump of the concrete mix. This characteristic is measured in terms of slump, the higher slump values
