What grade of concrete to be used for waterproofing of basement of apartment?
-
Water proofing is done using shotcrete not concrete. Basement should be built using concrete . Water proofing can also be done by polymer membrane systems called tanking ( refer to CIRIA). I used ACI 506 to design shotcrete. Its should be of 28Mpa strength using 12mm down aggregates.

What is the percentage of fineness content in OPC for construction works?
-
The most active part of cement is the material finer than 10-15 nanometer. Furthermore, a fine grind of cement clinker is able to coat the surfaces of aggregates more completely than coarse material enabling intimate contact of the resultant paste or mortar.

How to calculate admixture for transporting concrete for long distances to delay setting time in case of long-distance transportation in transit mixers?
-
The admixture which we use in the concrete for delaying its setting time then such type of admixtures are called as retarders. Gypsum is a retarding agent which we add in the cement during its manufacturing process. Gypsum is work as a starting agent as well as it restricts soundness in the cement.Read more

Rigid pavements because of their nature, allow for a larger variation in subgrade material (in terms of strength), unlike flexible pavements. That is why rigid pavements can be built over almost any kind of soils with appropriate ground improvement. The general range for CBR is 2% to 14% or 15%. IfRead more
Rigid pavements because of their nature, allow for a larger variation in subgrade material (in terms of strength), unlike flexible pavements. That is why rigid pavements can be built over almost any kind of soils with appropriate ground improvement.
The general range for CBR is 2% to 14% or 15%. If it is found below 6%, then the code specifies some necessary subgrade improvement before laying the concrete slab directly over it.
Also, the CBR could be increased up to say 40% or 50% by ground improvement, and still, the subgrade may be fit for rigid pavements.
