For quality control of Portland cement, the test essentially done is
-
If 1500 g of water is required to have a cement paste 1875 g of normal consistency, the percentage of water is,
-
Under normal conditions using an ordinary cement, the period of removal of the form work, is
-
Wp and Wf are the weights of a cylinder containing partially compacted and fully compacted concrete. If the compaction factor is 0.95, the workability of concrete is
-
For given water content, workability decreases if the concrete aggregates contain an excess of
-
M10 grade of concrete approximates

For ensuring quality of concrete, use
-
The mixture of different ingredients of cement, is burnt at

The risk of segregation is more for
