Comparative Analysis On The Strength Of Concrete Made With

Normal concrete can be produced from different aggregate and it impart different properties to the resulting concrete. The most important property of a concrete is its compressive strength. For the purpose of this work, the two type of coarse aggregate are, local gravel and granite. The fine aggregate is normal sand bought from a local distributor.

IMPACT OF COARSE AGGREGATE ON COMPRESSIVE

aggregate and any changes in coarse aggregate type can affect its strength and fracture properties. The paper examined the impact of coarse aggregates on compressive strength of concrete. Slump and compaction factor tests were conducted on the mixture of quartzite and crushed granite course aggregates, and quarry dust (fine aggregate).

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used to make high-strength concrete, it is easier to do so with coarse aggregates below 12.5 mm (Y, in.) (ACI 363-95).

Experimental Case Study of Recycled Aggregate Concrete

The aggregate is generally coarse gravel or crushed rocks such as limestone, or granite, along with a fine aggregate produced by using fully fresh coarse aggregate in concrete mix. Whereas in recycled asphalt pavement concrete mixes Result of Aggregate Impact Value Test on Coarse Aggregate (20mm) and RAP Table 5:- Result of Aggregate

Coarse Aggregate Properties

The gravel performed poorly because of the weak bond between the aggregate and the cement paste. The granite aggregate, on the other hand, gave the worst results because of its mineral composition. In their granite sample, they found a mineral that is unstable in moist environments which is why the granite specimen's results were poor. Figure 4

What Is Coarse Aggregate Requirements of Good Coarse

Coarse aggregates are a construction component made of rock quarried from ground deposits. Examples of these kinds of ground deposits include river gravel, crushed stone from rock quarries, and previously used concrete. Coarse aggregates are generally categorized as rock larger than a standard No. 4 sieve (3/16 inches) and less than 2 inches.

Aggregates for Concrete

AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 µm (No. 200) sieve is called “fine aggregate” or “sand,” and larger aggregate is called “coarse aggregate.” Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.).

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.
