This study studied the properties of lightweight geopolymer concrete that contained recycled lightweight block
aggregate. The recovered blocks are classified as coarse aggregates after being crushed.To reduce greenhouse gas emissions,
geopolymers have the potential to be used to create new, environmentally beneficial materials. A new class of building materials
called geopolymer concrete (GPC) has a replacement for regular Portland cement concrete (OPCC) and are capable of
revolution in the construction sector.
