Feb 13, 2021 To shape concrete, aggregate is mixed with cement that is used to lay the base of a road or even a roof in a building.. Many ingredients, such as sand, gravel, stone, crushed rock and sometimes even waste slug from the iron and steel industry, are used to form aggregates.. In general, aggregate is graded as fine and coarse.

The volume or yield of the concrete affords, in fact, one method of determining the best pro portions of aggregates. If the proportion of cement is kept the same, that mixture of coarse and fine aggregates will be the best which will give the smallest volume of concrete from a cer tain weight of aggregate.

• Defining coarse sand (between the #4 and #30) and fine sand (finer than the #30) • ACI 302.1R-04 recommends the sum of material retained on the #8 and #16 sieves should be a minimum of 13% to avoid edge slumping

How to Calculate Cement, Sand and Coarse Aggregate

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

Bulking of Sand If the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. If we need to add 1m 3 sand in the concrete mix ratio, we take 1.3 m 3 (30% more). The reason for that is the moisture content present in the sand makes it a little bulkier.

The 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

Aggregates Cement

Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.

Aggregates for Concrete

• 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 are divided into either ‘coarse’ or ‘fine’ categories. Coarse aggregates are particulates that are greater than 4.75mm
