The use of crushed concrete aggregates (CCA) (formerly referred to as recycled concrete aggregate (RCA)) is increasing, particularly for low-grade applications, where quality is of less importance. In higher value applications, such as structural concrete, further research has been required to understand the effect of coarse CCAs on the mechanical properties and durability performance. This

Evaluation of Strength Characteristics of Concrete

The suitability of crushed stone dust waste as fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Two basic mixes were selected for natural sand to achieve M25 and M30 grade concrete. The equivalent mixes were obtained by replacing natural sand by stone dust partially and fully.

2 天前  Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete

Concrete with recycled concrete aggregate and

2011-4-1  Research highlights We examined the effect of high inclusion levels of RCA and CCB on the properties of recycled concrete. The inclusion of CCB by up to 50% has crucial effect on compressive and cylinder splitting strengths. The effect of CCB is relatively limited on the flexural strength. The content of crushed clay bricks will markedly increase the permeability.

Evaluation of the Characteristic of Heavyweight Concrete

2015-10-12  concrete with natural aggregates on the ability to absorb radiation. RESULTS AND DISCUSSION Physical and mechanical properties of concrete The results of testing the physical properties of aggregates for heavy concrete from steel slag and normal concrete from fine aggregate (natural sand), coarse (crushed stone) obtained the following data:

Aggregates Portland Cement Association

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
