Coarse aggregates 1) Fine aggregates:- The aggregates whose size is less than 4.75 mm are known as fine aggregates. Fine aggregate is also known as sand. 2) Coarse aggregate:- The aggregate whose size is greater than 4.75 mm is known as coarse aggregate. Stone is also known as coarse aggregate.
1.Size of Coarse Aggregates: The size of the coarse aggregate depends on the use of the concrete is to be poured. For large-scale concreting operations without complex …
Explanation: Many factors dictate aggregate size, including method of placement, regional availability of materials, admixtures etc. In order to minimize cracking, it is ideal to use a mix design containing aggregates ranging from natural sand, to 1-1/4" at an average of 18-22% of each size by weight. Maven Group LLC Answer: 3/4 inch crushed stone
Below i am giving detail procedure and calculation for M30 grade and 10 mm size coarse aggregate as you given insufficient data for mix design i assume some data as per IS 456:2000 and IS 10262, Step 1 — Determination Of Target Strength Himsworth constant for 5% risk factor is 1.65. ftarget = fck + 1.65 x S = 30 + 1.65 x 5.0 = 38.25 N/mm2 Where,

Coarse aggregate is any material whose particles are anywhere from 3/8 inches and 1.5 inches in width. This is the size of aggregate often used in road construction. Fine aggregate: Most fine aggregates consist of crushed stone or natural sand. Most of the present particles must be able to pass through a 3/8-inch sieve.
As per clause 8.2.4.2 of IS: 456. Maximum cement content = 450 kg/m3. Step 5: Estimation of Coarse Aggregate proportion:-From Table 3 of IS 10262- 2009, For Nominal maximum size of …

A.: If the quantities of coarse aggregate, fine aggregate, cement and water are the same for both mixes, the mix with l l/2-inch aggregate will have greater slump and will probably bleed more. If both mixes are plastic the resulting strengths of the two mixes will probably be about the same.
1. Maximum Aggregate Size. The maximum size of coarse aggregate is one of the factors that controls water demand to achieve certain workability. It also dictates quantity of fine aggregate …
Jan 15, 2016· For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 inch.

What is the meaning of 1 2 4 ratio? The proportion is used for showing the amount of cement, sand, and coarse aggregate in the concrete. The specification should also say if those proportions are by weight or volume. In mix design the proportion 1: 2:4 means, 1 part of cement is mixed with 2 part of sand and 4 part of coarse aggregate.
There are two basic types of aggregates based on their sizes. Coarse Aggregate Fine Aggregate 1)Coarse Aggregate When the particles of an aggregate are retained on sieve # 4 (4.75 mm) and do not pass from them are known as coarse aggregates. It includes cobbles, gravels, and boulders. Coarse Aggregate is one of the main components of concrete.
Volume of 1 Kg of Cement = 1/1440 = 0.000694 cum Volume of 01 bag (50 kg) of cement = 50 X 0.000694 = 0.035 cubic meter (cum) Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4) Volume of Sand required would be = 0.035*2 = 0.07 cubic meter (cum) Volume of Aggregate required would be = 0.035*4 = 0.14 cubic meter (cum)
