Ballistic perforation resistance of thin concrete slabs impacted by
It should be noted that the cylinder compressive strength of the C35 concrete was higher than the cube compressive strength because of the difference in curing time for the DIC tests. Also, the ratio f t / f c decreased for concrete from low-strength to high-strength, similar to previous works [ 4, 11, 41 ].

CPD 26 2014: Introduction to waterproof concrete
C35. The C35 mix has a water-cement ratio of 0.55, and a cubic metre might comprise of 950kg of stones, 900kg of sharp sand, 200kg of blended cement, 110l of water (which is actually less by volume than in the waterproof concrete) and a small amount of WRA. This totals 2,260kg, and some air will complete the cubic metre.
