4 banyak agregat kasar dapat memperbesar resiko segregasi pada beton. Sedangkan penggunaan bahan pengisi (filler) diperlukan untuk meningkatkan viskositas beton guna menghindari terjadinya bleeding dang segregasi, untuk tujuan tersebut dapat digunakan fly ash, serbuk batu kapur, silica fume atau yang lainnya (Persson, 2000).

Fine and coarse aggregates make up the bulk of a concrete mixture. Sand, natural gravel, and crushed stone are used mainly for this purpose. Recycled aggregates (from construction, demolition, and excavation waste) are increasingly used as partial replacements for natural aggregates, while a number of manufactured aggregates, including air-cooled blast furnace slag and bottom ash are also ...
Compressive strength of concrete at an elevated temperature is of primary interest in fire resistance design. Compressive strength of concrete at ambient temperature depends upon water-cement ratio, aggregate-paste interface transition zone, curing conditions, aggregated type and size, admixture types, and type of stress . At high temperature ...

Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.

The concrete mix M20 and M25 are used for casting cubes, beams and cylinders for various laboratory tests. Variation in slump, compressive strength, flexural strength, split tensile strength tests are conducted in laboratory for M20 and M25. From study, it is found that strengths are reducing with increasing percentage of crumb rubber.

If the coarse aggregate is not angular, the volume of coarse aggregate may be required to be increased suitably, based on experience. Note 2: For pump-able concrete or congested reinforcement the coarse aggregate proportion may be reduced up to 10%. Hence, Volume of coarse aggregate per unit volume of total aggregate = 0.62 x 90% = 0.558 Volume ...
Recycled-concrete aggregate generally has a higher absorption and a lower specific gravity than conventional aggregate. Absorption values typically range from 3% to 10%. The graph is a comparison of water absorption of three different recycled aggregate particle sizes and one size of natural and lightweight coarse aggregate.
