Effect of Aggregate Properties on the Crushing Strength of
Sep 05, 2015· This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone brick khoa of aggregates.

Concrete recycling Wikipedia
Uses of recycled concrete. Smaller pieces of concrete are used as gravel for new construction projects. Subbase gravel is laid down as the lowest layer in a road, with fresh concrete or asphalt poured over it. The US Federal Highway Administration may use techniques such as these to build new highways from the materials of old highways. Crushed recycled concrete can also be used as the dry

Properties of recycled concrete aggregate under different
The coarse recycled concrete aggregate was obtained by crushing a laboratory produced primary concrete at age of 28 days. About 250 cubes of dimension 15 ∗ 15 ∗ 15 cm were crushed to produce the recycled coarse aggregates using mix design ().After crushing of these cubes, the maximum nominal size of recycled coarse aggregate used in mixes 2, 3 and 4 was 25 mm.

Strength of Coarse Aggregates
While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself. However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk aggregate, and performance of aggregate in concrete.
