Correlations between Mechanical Properties of High-Strength Concrete

The Use of Additives to Enhance Properties of Pre- Formed Foamed Concrete

“…12. [4], [37], [38]. It can be seen that for a given compressive strength, the FCa mixes exhibited lower E-values than the FC mixes, while the E s for NWC was higher than for both FC and FCa.…”

The Serviceability Considerations of HSC Heavily Steel Reinforced Members under Bending

“…It was shown that [11] , however the ACI expressive for f r is highly conservative for HSC. The first author of this research, tasted another 12 HSC beams in flexure with the main variable ratio of ρ and ′ ρ [5] and it was found that a value of c r f 0.63 f ′ = (MPa) for f r can predict the cracking moment with sufficient accuracy for first crack observed in HSC beams.…”

“…( ρ and ′ ρ , respectively) and spacing of lateral ties as the main parameters. They compared the obtained experimental cracking moments with the corresponding moments calculated by using different approaches [7,[11][12][13][14] for the beams tested. Different representative expression suggested by [7,[11][12][13][14] were testified while using Eq.…”

Economical Reactive Powder Concrete Cast Using Available Materials in North Sinai, Egypt

“…Larger amounts of silica fume (SF) (more than 10% of the cement weight) are used to 'refi ne' the particle structure and thereby reduce the total pore volume and the average pore size. The size and spherical geometry of SF particles allow them to fi ll effectively the voids between the larger and angular cement grains [16].…”
