Nov 21, 2008  The influence of coarse and fine aggregates on the strength of the concrete was evaluated. Durability of the concrete made with marble and GBFS was found to be superior to the control concrete. In the specimens containing marble, granite and GBFS there was a much better bonding between the additives and the cement.

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).

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.

Environmental Impact of Aggregates - Concrete

Environmental Impact of Aggregates. Aggregates form the major part of concrete and are derived from many types of rock. Granite and limestone are extracted from quarries, crushed and graded. In many parts of the UK, land-based or marine sand and gravel are available: these require some processing, such as washing and grading, before use in ...

Theophilus Yisa Tsado ABSTRACT - IJERT

Coarse aggregate is natural gravel or crushed stone usually larger than 5 mm and usually less than 16 mm in ordinary structure [1, 7, 9, 28, 29]. In this research, the emphasis will be on coarse aggregate. Aggregate, part of which is coarse, is used primarily for the purpose of providing bulk to the concrete.

Coarse Aggregate in Concrete Construction Shyam Steel

COARSE AGGREGATE. Coarse aggregates refer to irregular and granular materials such as sand, gravel, or crushed stone, and are used for making concrete. In most cases, Coarse is naturally occurring and can be obtained by blasting quarries or crushing them by hand or crushers. It is imperative to wash them before using them for producing concrete.

Materials and Aggregates 101 Shelby Materials

Fine and Coarse (Sand and gravel) Aggregates are divided into two distinct categories — fine and coarse. Fine aggregates generally consist of natural sand with most particles passing through a #4 sieve. Coarse aggregates are any particles greater than that, but generally range between 3/8 and 1.5 inches in diameter.
