Optimum mix parameters of high-strength self-compacting concrete with ultrapulverized fly ash

Packing density measurement and modelling of fine aggregate and mortar

“…As concrete mixes are composed of particles as well, the packing of the constitutive particles should also be playing certain roles in their behaviour. In fact, research on concrete has, for several decades, revealed that the packing of the particle system has significant effects on the rheological properties of concrete mixes [3][4][5][6][7][8][9][10][11][12][13][14]. However, the research carried out so far is still not sufficient to allow accurate measurement and prediction of the packing density and rheology of cement paste, mortar and concrete.…”

Aplicación del diseño estadístico de mezclas para la formulación de pasta autocompactante

“…Like was shown in several studies (1)(2), it is possible to prepare self-compacting concretes without using viscosity agent; in order to remain in the context of the valorization of local materials, this parameter will not be integrate in the preparation of the cement pastes.…”

Fresh, Mechanical and Absorption Characteristics of Self-Consolidating Concretes Including Low Volume Waste PET Granules

“…SCCs were developed firstly in Japan in 1980s to increase stability and durability of concrete structures [1][2][3][4][5]. SCC decreases the risk of poor workmanship during casting and compaction of concrete.…”
