Effect of water cement ratio and Aggregate Size on

Effect of aggregate size. Aggregate is an important factor Affecting concrete strength. The most important properties of concrete are shape, texture, and size of aggregate. Maximum size affects the strength in several ways. Larger particles reduce the specific surface area of aggregate which leads to a reduction in bond.

Effect of recycled coarse aggregate and foundry sand on

In this paper, the possibility of utilising foundry sand and recycled coarse aggregate (RCA) obtained from a ready-mix concrete plant for making self-compacting concrete (SCC) was evaluated. In this experiment, 25 concrete mixes were made in which the substitution of RCA was 0, 25, 50, 75 and 100% as coarse aggregate and substitution of foundry

Effects of Coarse Aggregate Size on the Compressive

Also, the results show that the compressive strength increases with increasing aggregate size up to 12.5 mm, while the concrete produced using 20 mm had greater compressive strength than those produced using 25 mm aggregate. This established the importance of ensuring that the right aggregate size is used in the production of concrete.

PDF Influence of Aggregate Size on Concrete Strength and Shrinkage

Also, smaller-sized aggregate having a higher surface area would be expected to provide stronger bond between the cement paste and aggregate particles. However, a decrease in the aggregate size will increase the shrinkage.2 A decrease in the nominal maximum aggregate size from 1-1/2 in. (38 mm) to 3/4 in. (19 mm), for example, will increase

Effect of Recycled Concrete Aggregates and Natural

Self-compacting concrete (SCC) is a very fluid concrete in which its compaction can take place under the effect of its own weight, without vibration. SCC is characterized by its high volume of paste, and the use of superplasticizers. Very little work is reported in the literature on the use of recycled aggregates in SCC.

Influence of Aggregate on Workability of Self-Compacting

The workability of self-compacting concrete is influenced greatly by aggregate. In this study, the effects of aggregate gradation, maximum particle size, sand percentage and particle shape on the workability of self-consolidating concrete were investigated. The results showed that the compressive strength and workability of self-compacting concrete were increased by increasing the particle
