Influence of Aggregate Grain Size on the Formulation of Sand Concrete in the Construction Industry in Congo

The objective of this work was to study the influence of the grain size of the sands of the Mfilou, Djiri and Congo River quarries and crushing on the performance of sand concrete. The method adopted consists of a physicomechanical characterization of the selected sands taken as aggregates by the following tests: granulometric analysis, bulk density, specific gravity, sand equivalent.

Construction aggregate - Wikipedia

Construction aggregate, or simply aggregate, is a broad egory of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as

Aggregate Concrete - an overview ScienceDirect Topics

NAC, Natural aggregate concrete; RAC, Recycled aggregate concrete. The measured concrete strength in selected tests was considered as mean concrete compressive strength f cm . For NAC mixes, the 28-day characteristic compressive strength f ck , tensile strength f ctm , modulus of elasticity E cm and creep coefficient φ t , t 0 were calculated according to Eurocode 2 – Part 1 provisions

What is a Concrete Aggregate? with pictures - wiseGEEK

Using aggregate makes concrete much stronger, with the aggregate acting as a type of reinforcement. The aggregate increases the lifetime of the concrete, and makes it more durable. Contractors can choose from fine aggregates, made from small particles of material, and coarse aggregates, which are made with large chunks.

This video talks about the role of aggregates in concrete mixture design.

Aggregates for Concrete as per American Standards - ASTM PDF

The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. The aggregates may be natural, manufactured, or recycled. The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate. In this article, we discuss …

Aggregate in Concrete - The Concrete Network

Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material
