Kindly furnish the relation between 7 days strength & 28
days compressive strength of Cement Concrete cubes. Can you
clarify whether the relation gets altered due to various
WATER-CEMENT ratios and type of cements?

Answer Posted / ramir v. agustin

In concrete testing samples aged in seven days should yield
70 percent of the specified strengt requirment and 28 days
sample should yield 100 percent of the compressive strength
required.Water cement ratio and amount of cement plays a
very important role in the production of good concrete.The
stregth of concrete depends on its water cement ratio

In an aggregate blending plant, water is sprayed before blending is performed. If the fine content in aggregate is as high as 25 %, will not the fines form into lumps / balls and distribution will not be uniform ? Further, the fines will stick onto the interior of pug mill and its content will be low. The mixed material is stockpiled for weeks / months before use. Will it not be better that blending is done in dry condition, and water will be added only during compaction at site. Please forward your comments and suggestions.
