7 Deleterious material Water demand (strength), bond, cohesion and durability Surface texture of aggregate influences the bond between the aggregate and cement. Smooth surface such as that found on gravels will have a poor bond. Crushed aggregates have a rough texture and give a good mechanical bond with cement. However, gravel or rounded aggregates have been used for high .
· Thus, CCA—combined with the fine aggregate or "dust" from the crushing process—has a higher demand for water and cement, resulting in the potiental forgreater shrinkage and lower strength. Because the crushing process produces concrete aggregate with jagged edges and dust, the resulting concrete was considered too harsh for appliions .
to minimise voids and reduce water demand in concrete, crusher dusts are blended with fine natural sand to aid workability and finishability [8]. The particles passing the 63 m sieve, referred to as fines in this paper, can greatly affect the fresh properties of concrete, as they increase the specific surface area of the fine aggregate, thus requiring an increase in water/admixture .

Generally, coarse crushing equipment used in aggregate production is rotary crusher, jaw crusher and impact crusher. According to the production capacity (coarse crushing > 1200t/h), raw materials contain more soil and the market demand for aggregate products, usually, coarse crushing equipment is the rotary crusher. 2. Medium/Fine Crushing ...
The aggregate occupies ~7075% of the volume of concrete, so its quality is of great importance. Aggregates may affect the following properties of concrete: –Strength –Durability –Structural Performance –Economy Aggregates have 3 main functions in concrete: 1) To provide a mass of particles which are suitable to resist the action of applied loads show better durability then .
Crushed stone is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Crushed aircooled blastfurnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanliness, grading, moisture content, and other properties is expected. Close to half of the coarse .
