Exposed Aggregate

Exposed aggregate concrete can almost be compared to a piece of granite or marble transformed by polishing: A plain, unremarkable surface has been stripped away to reveal the exceptional beauty lying beneath. In the case of concrete, that beauty is in the form of decorative aggregate, either natural or manufactured.

WHAT ARE THE PROPERTIES OF AGGREGATES FOR CONCRETE

Oct 01, 2016Impact Value of Aggregate; Abrasion Value of Aggregate; 1. Composition. Aggregates consisting of materials that can react with alkalies in cement and cause excessive expansion, cracking and deterioration of concrete mix should never be used. Therefore it is required to test aggregates to know whether there is presence of any such constituents in aggregate or not. 2.

HOW TO CLASSIFY AGGREGATES ACCORDING TO SIZE

Jul 07, 2014IS specifications classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone-1 to grading Zone-4. The four grading zones become progressively finer from grading Zone-1 to grading Zone-4. 90% to of the fine aggregate passes 4.75 mm IS sieve and 0 to 15% passes 150 micron IS sieve depending upon its grading zone.

If the proportions are based on weight, use 4 pounds of coarse aggregate and 2 pounds of sand for every pound of cement. To make the concrete, though, you still need to know the required water-cement ratio. If the proportions are based on volume, use four shovelfuls of coarse aggregate and two shovelfuls of sand for every shovelful of cement.
