### Different Types & Sizes of Aggregate for Concrete

11/08/2018· For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. SIZES OF AGGREGATE. At the most general level, aggregates come in two varieties: [1] Fine Aggregate [2] Coarse aggregate [1] FINE AGGREGATE. Fine Aggregates are usually sand or

Concrete base made using sand, cement, water and aggregate. When it comes to producing the correct concrete mix for the particular job you are doing (more can be found on mixing cement in our project here), this is very much down to the type of aggregate that is used in the mix and the quantities of aggregate, cement and water that’s used.Aside from the amount of aggregate used in a concrete

• Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete. • Aggregates in any particular mix of concrete are selected for their durability, strength, workability and ability to receive finishes. • For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine

Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix. Economy is another reason for thoughtful aggregate selection. You can often save money by selecting the maximum allowable aggregate size. Using larger coarse aggregate typically lowers the cost of a concrete

More### HOW TO DECIDE MAXIMUM SIZE OF COARSE AGGREGATE

23/03/2015· For the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate. In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement. This will also reduce the heat of hydration and the corresponding thermal stresses and shrinkage cracks. But in practice the

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed

This mixing ratio will give you a concrete mix that is strong, durable, and good for most concrete projects. A cubic yard of concrete will fill an area 8 feet wide by 10 feet long by 4 inches thick, or 80 square feet @ 4 inches thick. At 6 inches thick a cubic yard of concrete will fill an area 52 square feet and at 5 inches thick, it will fill an area that's 65 square feet. 4000 psi concrete

More### How Coarse Aggregate Affects Mix Design of Concrete?

It is reported that, high maximum coarse aggregate size leads to lower water demand in the mixture since such aggregate has lower surface area compare with small coarse aggregate size. As far as shape is concerned, rounded shape aggregate provides economical mix design for normal strength concrete.

The character & performance of the concrete mix solely depends on the gradation, maximum size, unit weight, and moisture content of any aggregate. Proper selection of maximum permissible aggregate size in concrete can reduce the cost considerably. The requirements of cement in a concrete mix is lowered with the use of greater coarse aggregate. Least cement (within acceptable limits for

More### Concrete Mix Ratios Cement, Sand, Aggregate and Water

Concrete mix ratio of 1:3:3 On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio. It means the more the water, the weaker the
