Transport properties of self consolidating concrete interracialdatingevents com

SCRC mixtures with a water-binder ratio (w/b) of 0.32; total binder content of 500 kg/m3 (842 lb/yd3); and crumb rubber content of 0, 10, 20, and 30% by fine aggregate volume were produced and tested.

Fresh properties testing revealed that the use of crumb rubber as a fine aggregate diminished the filling and passing ability of SCRC.

This paper presents the transport and mechanical properties of self consolidating concrete that contain high percentages of low-lime and high-lime fly ash (FA).

Self consolidating concretes (SCC) containing five different contents of high-lime FA and low-lime FA as a replacement of cement (30, 40, 50, 60 and 70 by weight of total cementitious material) are examined.

This study reports the findings from an investigation carried out to study the effect of the mixture variations on the durability of medium-and high-strength self-consolidating concrete (SCC).The results indicated that SCC, for both grades of strength, made with PFA showed much lower diffusivity values in comparison with other mixtures, whereas the SCC mixtures with VMA showed higher diffusivity. This paper presents the fresh, mechanical, transport, and durability performances of self-consolidating rubberized concretes (SCRCs).The results showed that SCC mixtures, for medium- and high-strength grades using PFA followed by LSP, have lower permeability properties compared with normal concretes.SCC made with VMA had a higher sorptivity, air permeability, and water permeability compared with other SCC mixtures, which can be attributed to higher water-cement ratio (w/c) and lack of pore filling effect.
