Crushed sand, with particle size less than 5 mm, is a by product obtained in the process of rock crushing to manufacture gravel or coarse aggregates. Thus, many of the sand properties (chemical and mineralogical compositions .etc.) are related to the source rock.

Apr 03, 2013· While developing their concrete mixes, they made some unique discoveries — the most intriguing was a mix and process that Cook says produced samples exceeding 40,000psi compressive and 5,000psi flexural strength with no reinforcement (well beyond what they needed for ModaCrete). By 2012, ModaCrete's slabs were ready to be introduced to ...

lower paste volumes in the concrete. Using the largest size aggregate possible and medium to coarsely graded fine aggregate can attain this. Smaller maximum size aggregate such as 3/8 inch () can be used to produce very high compressive strength but required properties like creep, shrinkage, and modulus of elasticity may be sacrificed.

Often it is observed, attainment of early compressive strength in concrete is a challenge. Researchers have tried various admixtures to achieve the objective. This work addresses the issue of achieving early compressive strength in concrete using a bacterium called Sporosarcina pasteurii. The bacterium is characterised with the ability to precipitate calcium carbonate in the presence of any ...
