Filler materials Used In Concrete

Filler materials are gaining widespread popularity and becoming very important because they help in increasing some of the mix properties and also lower the usage of binder which is usually more expensive
Here is the table showing some common filler materials along with binders

Material	Binder	Filler	Importance of filler
Concrete	cement	gravel, stone , sand	cheaper
Drywall	gypsum	cardboard	tenacity, volume, main part
Particle board	Synthetic Resin, glue	sawdust	tenacity, volume, main part
Plastic explosive	Plasticizer, oil	explosive	explosiveness
Tyre rubber	rubber	Soot	Volume, better mechanic properties
Resin epoxy	epoxy	Microspheres	Improve viscosity of resin
