AND FLEXURAL STRENGTH OF CONCRETE MADE FROM .

This research, comparison of compressive and flexural strength of concrete made from different coarse aggregates written in accordance to British standard. The different sizes of coarse aggregates used are; 10mm, 12 mm and 20mm. These aggregates were used to produce concrete cubes (150mm x 150mm x 150mm) and beans (150 x 150mm x 150mm).

Relation Between Compressive and Tensile Strength of Concrete

Relation Between Compressive and Tensile Strength of Concrete

In experimental concrete, entirely smooth coarse aggregate led to lower compressive strength, typically by 10 percent, than when roughened. It seems that the .

Strength of Coarse Aggregates

Strength of Coarse Aggregates

While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself. However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk aggregate, and performance of aggregate in concrete.

A field index to determine the strength characteristics of crushed aggregate. More than 110 rocks and aggregate samples were tested according to British Standard and ASTM. The laboratory tests included the Schmidt hammer and point load for rock material while the crushing impact and Los Angeles abrasion test were undertaken on the aggregates.

Strength of Lightweight Glass Aggregate Concrete | Journal ...

Expanded glass aggregate with relatively high crushing resistance and low water absorption is now available from a manufacturing plant in Hungary. The new aggregate is similar to conventional lightweight aggregates, but the ratio of density of concrete to compressive strength is much more favorable to making structural concrete.

Advances in Materials Science and Engineering Hindawi

Concrete samples of three different compressive strengths were prepared as per ACI mix design method from each of these aggregate samples. Compressive strength of concrete that could be achieved with brick aggregate varied between 19 and 28 MPa, whereas, for stone aggregate, compressive strength varied between 24 and 46 MPa.
