This paper presents a study on the fresh and hardened properties of selfcompacting concretes using residual calcareous slurr y from the paper industry as filler in proportions of 35% and 50% by weight of cement. T h e r e s u l t s w e r e c o m p a r e d w i t h s e l f -c o m p a c t i n g c o n c r e t e s a d d e d with limestone powder at the same proportions. The examined properties i n c l u d e w o r k a b i l i t y, c o m p r e s s i v estrength, elastic modulus, porosity and water abortion.Workability of fresh concrete was determined by using the slump-flow test, L-box test and V-funnel test.The compressive strength was determined at different ages (3, 7, 28 y 90 days), the permeability tests were carried out at 28 days and the elastic modulus at 90 days.The results show that it is possible to successfully utilize calcareous slurry as mineral admixtures in producing medium strength selfcompacting concrete.Although the self-compacting concrete added with 35% of limestone powder showed an improvement of 16,4% in compressive strength, compared with the selfcompacting concrete added with 35% of calcareous slurry.At the same time, this concrete presented low porosity and water permeability.
