Report Errors
This study aims to manufacture non-sintering cement (NSC) by adding phosphogypsum (PG) and waste lime (WL) to granulated blast furnace slag (GBFS) as sulfate and alkali activators. This study also investigates the pore structure of NSC matrix. The result of experiment of pore structure properties, showed no considerable difference for total pore volume by cement mixing ratio but shows a large distinction in distribution of pore diameter. On the whole, pore-diameter of paste of NSC show that occupation ratio of pore diameter below 10 mm is larger and is smaller than ordinary portland cement (OPC) and blast-furnace slag cement (BSC) at pore diameter of over 10 nm. Such a reason is that the hydrate like C-S-H gel and ettringite formed dense pore structure of NSC matrix.
