What are the Correct Concrete Mixing Ratios
When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mixture. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength …
Aggregate in Concrete
In construction terms, aggregate refers to granular materials such as sand, gravel, or crushed stone. These components, when combined with cement and water, give birth to what we commonly know as concrete. A key point to remember is that aggregate constitutes about 60-75% of concrete's total volume.

Determination of Aggregate Impact Value
Procedure of Aggregate Impact Test. The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled. (i) Sieve the material through 12.5 mm and 10.0mm IS sieves. The aggregates passing through 12.5mm sieve and retained on 10.0mm sieve comprises the test material.
Plain Concrete vs. Exposed Aggregate: How to Settle the …
But what you really want to know is which concrete finish is going to be more expensive. The short and sharp version is that plain concrete is cheaper ($85 to $135 per m2) than exposed aggregate concrete ($100 to $150 per m2) – but the figures don't tell the whole story. For example, plain concrete is easier to install so you can enjoy a ...
