Aggregates for Concrete - Civil Engineering

aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 5-6 shows these limits for fine aggregate and for one size of coarse aggregate.

The Effect of Aggregate Size on The Strength of Concrete

several factors such as, mixing ratio, aggregate size, texture, coarse and fine aggregate, compaction method, curing period and some parameters have been discussed in literature review. The results showed the concrete aggregate size of 20mm has a 45.7% higher compressive strength than the concrete aggregate size of 10mm.
