Demystifying Concrete Mix Ratios A Balancing Act A concrete mix is a carefully balanced combination of three main ingredients Aggregates These are inert particles typically consisting of gravel or crushed stone coarse aggregate and sand fine aggregate They form the bulk of the concrete mix providing structure and reducing the amount of expensive
Cement is a key ingredient of concrete typically making up 10 to 15 percent of the concrete mix by volume Portland cement and portland limestone cement are the most common types of cement used in concrete In concrete a paste made of cement and water is mixed with aggregates sand gravel or crushed stone As the cement reacts chemically
The ratio of 1/2/4 in concrete grade shows the perfect concrete mix has materials that make the concrete strong and less likely to crack It s great for many construction projects The 1 2 4 concrete mix is a time tested and proven formula that delivers consistent high quality results every time
High strength concrete suitable for precast concrete heavy duty floors To make 1 cubic metre of concrete you will need 10 bags cement cubic metres sand cubic metres stone Small batches Use containers such as buckets drums or tins Use the same size container for measuring all the materials in a batch
To help prevent this Air Entrained concrete mix was created It is sometimes referred to simply as exterior mix In really simple terms an exterior mix uses an admixture during the batching process to create billions of microscopic bubbles in the concrete When the concrete cures the bubbles harden and form tiny chambers
5 For example let s calculate the amount of cement sand and gravel for the M5 mix to fill one cubic yard of space Start by calculating the dry volume of the mix dry volume = × = cu yds Recall the percentages for this mix are 1 part cement > 1/16 =
