In order to create a durable concrete mix, it's essential to understand the basics of the concrete mix ratio. Simply put, a mix ratio refers to the proportion of different ingredients that are used to create concrete, including cement, sand, and aggregate. Basics of concrete mix ratio. First, let's discuss what a mix ratio is.
اقرأ أكثرThe ratio of fine to coarse aggregate is chosen as usual as 1:2. From the above table we know we need 250kg of total dry aggregate for our concrete. The general ratio of fine aggregate to coarse aggregate is 1:2, but it can be adjusted between 1:1.5 to 1:2.5 based on the grading of fine aggregate and size of coarse aggregate. Sand = 1 Part

اقرأ أكثرAggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
