Shrinkage of High-strength Concrete and High-flowability Concrete
HKIE Transactions, 2010Throughout the years, a large amount of research on the shrinkage of normal concrete with cube compressive strength up to 60 MPa has been carried out. Relatively, the amount of research on the shrinkage of high-strength concrete and high-flowability concrete is not as much.

Minimum Reinforcement in High‐Strength Concrete
Journal of Structural Engineering, 1990A dimensional analysis criterion is proposed to compute the minimum amount of reinforcement for high‐strength concrete members in flexure. Such an amount is assumed to be provided by the condition of simultaneous first cracking aand steel yielding. The fracture mechanics model utilized defines a brittleness number NP, which is revealed to be a measure ...

Testing High-Strength Concrete Compressive Strength
ACI Materials Journal, 1993Comparative testing reveals that high strength concrete (HSC) compressive strength values are greater by 5% when measured on 100 x 200 mm specimens. Moreover, the coefficient of variation on one set of three 100 x 200 mm specimens is as small as, or smaller than that for 150 x 300 mm specimens.

Evolution from High Strength Concrete to High Performance Concrete
Key Engineering Materials, 2014High strength concrete for the production of concrete railway sleepers was designed more than 20 years ago. The compressive strength of the concrete was very high from the start, but flexure strengths showed some irregular development - a decrease in time. Later, also a significant decrease of fracture properties was recorded.

Core Strengths of High-Strength Concrete
"SP-172: High-Performance Concrete - Proceedings: ACI International Conference, Malaysia 1997", 1999The effects of varying L/D ratios and core size on the strength of cores from large elements of high strength concrete (HSC) made both in the laboratory and field were examined. 154 cores representing 5 laboratory mixtures having moist-cured cylinder compressive strengths from 114 to 142 MPa at 5-years age and 101 cores representing actual field ...

Very High Strength Cement for Very High Strength Concrete
MRS Proceedings, 1984AbstractDuring 1984 summer, an experimental concrete column was cast in a 26-story high-building using a 100 MPa silica fume concrete. Only the coarse aggregate was selected specifically for this concrete. The cement used was an ordinary type 1 Portland cement. The superplasticizer was a naphthalene base.

Comparison between high strength concrete and normal strength concrete subjected to high temperature
Materials and Structures, 1996Two normal strength concretes and three high strength concretes, with 28-day compressive strengths of 28, 47, 76, 79 and 94 MPa respectively, were used to compare the effect of high temperatures on high strength concrete and normal strength concrete.
