Aggregate is one of the primary building materials and constitute of concrete. Aggregate material used in construction, includes sand, gravel, crushed stone, slag, recycled concrete etc. The aggregate has to undergo several tests and has to pass satisfactory results before it is used in concrete.

Determine how much coarse aggregate and fine aggregate you need for your mixture. Making concrete is a delicate balance, particularly if you are going to make ultra high performance concrete. The standard ratio is 11 percent Portland cement, 41 percent coarse aggregates (such as gravel or crushed stone) and 26 percent fine aggregates, such as sand.

High density concrete mix design. When using only MagnaDense as an aggregate, concrete with densities up to 4.0 t/m 3 is achievable. Mixing MagnaDense into concrete with other aggregates allows you to produce even heavyweight concrete with densities up to 5.0 t/m 3.

Internal Curing (IC) for cement is a practical way of supplying additional water throughout the concrete mixture. In other words, achieving better hydration and less waste of valuable cement. This is done by consuming absorbed water in Light Expanded Clay Aggregate (LECA) which is replacing some of the conventional aggregates in the mixture.

Cement hydration plays a vital role in the temperature development of early-age concrete due to the heat generation. Concrete temperature affects the workability, and its measurement is an important element in any quality control program. In this regard, a method, which estimates the concrete temperature during curing, is very valuable. In this paper, variable regression and neural ...

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. If necessary, a benefaction process such as jigging or heavy media separation can be used ...

Exposed-aggregate concrete pavement. Both gravel and crushed stone produce quality concrete. Gravel will have a lower water demand compared to crushed stone. Gravel is preferred for exposed-aggregate concrete in walkways and decorative applications. Crushed stone will usually exhibit a higher paste-aggregate bond.

The grading and maximum size of aggregates is important parameters in any concrete mix. They affect relative proportions in mix, workability, economy, porosity and shrinkage of concrete etc. Experience has shown that very fine sands or very coarse sands are objectionable – the former is uneconomical, the latter gives harsh unworkable mixes.

In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.
