### Recycled Concrete Aggregates: A Review

Compressive strength of RCA concrete can be influenced by the properties and amount of recycled aggregate. Several factors can influence the compressive strength in RCA concrete, including the water/cement (w/c) ratio, the percentage of coarse aggregate replaced with RCA, and the amount of adhered mortar on the RCA.

### Aggregates

In general, if the water-cement ratio is chosen correctly, a wide range in grading can be used without a major effect on strength. When gap-graded aggregate are specified, certain particle sizes of aggregate are omitted from the size continuum. Gap-graded aggregate are used to obtain uniform textures in exposed aggregate concrete.

### Different Types Sizes of Aggregate for Concrete

When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete.

This paper intend to recommends that recycle glass can be used as an alternate coarse aggregate in concrete and will have wide applications in aesthetic workings.

### Construction aggregate

Construction aggregate, or simply aggregate, is a broad category 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.

### Effect of specific gravity of coarse aggregate on

18-7-2013This study presents results on the influence of specific gravity of coarse aggregate on the interfacial transition zone, permeability, and strength of concrete. The aggregate variables studied in this work were specific density (085, 120, 180, 265) and water / cement ratio (025, 040, 0

### Classification of Aggregates Based on Size and Shape

22-7-2016Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 to 80 % of

### Aggregates: Physical Properties and Mechanical Properties

Aggregates generally occupy 65- 80% of a concrete's volume. Aggregates are inert fillers floating in the cement paste matrix for concretes of low strength. The strength of aggregates do not contribute to the strength of concrete for low strength concrete. The characteristics of aggregates impact performance of fresh and hardened concrete.

### ACI 211.1: Maximum Aggregate Size For Concrete Mix

In this post I shall discuss maximum aggregate size that can be used in design. Large maximum sizes of aggregates produce less voids than smaller sizes. Hence, concretes with the larger-sized aggregates require less mortar per unit volume of concrete, and of coarse it is the mortar which contains the most expensive ingredient, cement.
