Ex if std no: 1abcde, 161667 (a=6, b=1, c=6, d=6,e=7)
In my case std 174702
Q1) Design a concrete mixture proportions which will be used foroffshore concrete platform. Norway is a world leader on offshoreconcrete platforms with 1a of the world’s 30 larger offshoreconcrete structureslocated on the Norwegian continental shelf. The first of theseplatforms where the Ekofisk Tank installed in 1974 and the last wasTroll gravity based structure installed in 1996. The Sakhalinproject is located in a harsh and artic environment where concretestructures have proven excellent characteristics with a minimum ofmaintenance. 80 mm slump value is required for the Sakhalinproject. 28-days concrete characteristic strength is 2b MPa. It isrequired that no more than 1 test result in 100 will fall below thespecified strength. The fine aggregate has a fineness modulus of2.60 and Zone 3. For Coarse Aggregate (Uncrushed): SSD BulkSpecific Gravity: 2.65, Absorption Capacity: 2.b %, Total Moisture:1.c % and Dry Rodded Unit Weight: 1345 kg/m3. For Fine Aggregate(Uncrushed): SSD Bulk Specific Gravity: 2.70, Total Moisture: 3.d %and Free Moisture: 2 %. Cement: Portland Composite Cement, SpecificGravity: 2.97. For 0.e5 m3 of concrete, binder amount is calculatedas 120 kg (Use ACI Method of Mix Design)
