Structural grade concrete can be prepared using RBA as coarse aggregate ensuring higher cement content and lower W/C ratio in the mix design with respect to compressive strength property. View
However, building codes provides nominal and standard concrete mix ratios for various construction works based on experience and testing. These types of concrete mix ratios are discussed in this article.
The 1 2 3 concrete mix ratio refers to a simple blend used for general-purpose concrete, consisting of 1 part cement, two parts sand, and three parts gravel. This mix provides a balance of strength, workability, and durability, making it suitable for driveways, sidewalks, and other residential projects. 2.
Mechanical mixing of cement and immersion in water curing produces high compressive strength [14]. The effect of different parameters due to inclusion of blast furnace slag and fly ash based...
For concrete of 1:2:4 mix proportion, first two boxes of sand and one bag of cement should be dry-mixed thoroughly. Then, a dry mix of cement and sand is placed over a stack of 4 boxes of stone aggregates and the whole mixture is dry-mixed, turning at least three times to have a uniform mix.
