01-01-2008· Black coastal sand was added to the serpentine aggregates, to increase the Density of the concrete to be suitable for shielding of neutrons and gamma and X-rays. Nine cubes of each sample have been prepared (total of 54 cubes) 15 × 15 × 15 cm 3.

PREDICTION OF SLUMP AND DENSITY OF LIGHTWEIGHT CONCRETES …

Nhat-Duc Hoang et al. (2016) predicted the performance of conventional concrete using 95 mixing designs by measuring the slump with artificial neural network. Their independent parameters in A.N.Ns were crushed and natural sand, natural gravel, cement, water and super-plasticizer, and their measured parameter was slump.
