class 32.5; actual strength 35.0MPa C25 concrete mix (weight ratio): cement: Sand: Crushed Stone: water, =1:1.48:3.63:0.44 In each cubic meter of concrete, cement content: 370Kg; sand content: 549Kg; gravel: 1344Kg In the actual construction process, the mixture ratio of mortar and ...
A fixed weight ratio of cement/fine aggregate/total coarse aggregates mixtures of 1/1.75/2.95 was used to prepare concrete mixtures (the cement content in each concrete mixture was kept constant at 340 kg/m3). The weight ratio (wt%) of each PCE-1 and PCE-2 superplasticizer to cement was...
aYoung modulusbetween 50 and 60 MPa, and an ultimatetensile strainof 1% [1–5]. The termUHPCis commonly used to describe the cement-silica fume mixture with an extremely low water/cement ratio and ultra-finesilicasand (015–0.6 mm) as a replacement for ordinary sand. In fact, UHPC shoul...

Compressive strength is one of the most important properties of concrete in the hardened state. As well as compressive strength, other very important properties worth mentioning are compactness, workability, durability, cement class AFNOR NF EN 197–1 (2012), gravel/sandG/Sratio, granular rangeD/...
