Study of Mechanical Properties of Self Compacting Concrete Made by Broken Tile Waste

Self-compacting concrete is one kind of concrete under its weight flows and simultaneous with maintaining homogeneity, without need to vibrator can be filled mold and takes the shape of the container. This concrete due to high performance in construction doesn’t have any risk in aggregates separation. Also, self- compacting concrete has high strength and relatively durability. On the other hand, the existence of huge tile waste and sepulture of these waste by ceramic and tile factories indicates the importance of using this secondary product in the other industries, including the construction industry. Also, with apply of waste material environment can be healthy and safe. In present experimental study, firstly the self-compacting concrete mixing scheme was determined. Then, according to the obtained mixing scheme with replacing recycled aggregates with natural particles, samples with 0, 25, 50 and 100 percentages (by volume) have been made. It should be noted water to cement ratio and percentage of high plasticizer are constant. The amount of limestone and silica fume in all of the mixtures have been fixed. In prepared specimen’s slump test to determine efficiency and compression and water-absorbing tests in 3, 7, 14 and 28 days curing have been performed. Results of the present study show generally with increasing waste tile efficiency and compression strength decrease. Although, durability goes up. Also, especially, with replacing 100% of recycled material with exist particles major changes have been observed but up to 75% have not been seen.
