The new conception of selfcompacting concrete composition

Behaviour of Self-Compacting Concrete Columns Reinforced

Performance of concrete columns has been significantly improved by using composite material systems such as encased sections and concrete filled steel tubes. Different combinations of encased sections and steel sections have been widely studied. Steel sections and concrete have been used to construct composite columns with different cross-sections. The composite columns are usually constructed

Estudio de la adherencia del concreto autocompactante

The aim of this paper is to analyze the bond behavior of self-consolidating concrete that was obtained by means of the Beam Test performed within a large experimental campaign of characterization. Four types of SCC were studied with two strength levels (40 MPa and 60MPa) and two different types of granular skeletons, using two specimens at each age (3, 7, and 28 days).

PDF The Determination of the Rheological Properties of SCC

properties of Self-Compacting Concrete (SCC) several concrete rheometers and measurement systems exist. Based on the nature of Self-Compacting Concrete, the determination of the rheological parameters is more difficult than for other substances. This is due to the composition of the mixture, the coarse aggregates used and the

Decisions on the Manuals of History

And it was established that the one which left the most to be desired was the summary of the manual of the "History of the U.S.S.R.", which abounded in anti-scientific and crude conceptions from the Marxist point of view and manifested an extreme negligence particularly inadmissible for the constitution of a manual where "each word, each conception, must be weighted."

A rise at the Falls | Roads & Bridges

The I-190 northbound and southbound and S.R. 265 (Military Road) bridges were built in 1960 as part of the Lewiston Pump-Generating Plant, located near Niagara Falls, N.Y. They are owned by the NYPA. The three adjacent bridges had a combined width of 131 ft and were separated by a mere 2 in. Each superstructure was comprised of 12 simple spans

Mix Proportioning of High Performance Self-Compacting

High performance self compacting concrete (HPSCC) is typically proportioned with mineral and chemical admixtures leading to relatively high material cost. Such cost can be tolerated in high value added applications specially when cost savings can be realized using HPSCC in terms of reduction in size of reinforced concrete members.

Development of Mechanical Properties of Self Compacting

The concept of self-compacting concrete was proposed in 1986 by Professor Hajime Okamura (1997), but the prototype was first developed in 1988 in Japan, by Professor Ozawa (1989) at the University of Tokyo [2,3]. This new concrete was deliberately designed to be able to fill every corner of the form and encapsulate all reinforcement with maintained
