# concrete maximum aggregate size

### Maximum Aggregate Size CivilWeb Spreadsheets

BS EN 13877-1 limits the maximum aggregate size in concrete to one third of the spacing between reinforcing bars. This is a more onerous restriction than in US standards which specify a maximum aggregate size of ¾ of the minimum spacing.

### What nominal maximum sizes of aggregate are

Because maximum aggregate size can impact concrete properties such as shrinkage, and also the cost of concrete, the largest aggregate size consistent with the requirements of 26.4.2.1 should be permitted. With the w/cm fixed, the larger the nominal maximum size of aggregates, the lower the cement content for a given consistency. Or, stated differently, for a given cement content, the larger the nominal maximum size of aggregate,

But in the high-strength range, over 40 MPa (5800 psi), higher compressive strengths are usually obtained at a given w/cm with smaller nominal maximum-size aggregate (ACI 363R, ACI 214.4R). Similarly, higher flexural strength is obtained at a given w/cm with smaller nominal maximum size aggregate. Data from compression tests of concrete containing very large aggregates, 100 mm (4 in.)

2000-12-7 Information on Selecting Maximum Aggregate Size In general, smaller size aggregates have been shown to produce higher strength concretes, for a fixed w/(c+p) ratio. However, the use of the largest possible coarse aggregate may be an important consideration in terms of optimizing modulus of elasticity, creep, and drying shrinkage of the concrete.

### Nominal maximum size of coarse aggregate Curious

2020-11-4 The limitation of aggregate maximum size is to ensure the smooth placing of concrete. If the maximum size of aggregate is above the limit, the placing of concrete can be difficult, and there will be a possibility of concrete segregation. The aggregate will be separated from the concrete.

### Aggregate in Concrete The Concrete Network

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.
