In sugar
production industry, the lime obtained from the commercially available
limestone is quenched, filtered and used in the production of juice. The excess
lime added to the juice is removed from the juice in the carbonation boilers
with the help of CO2. The mud part of the remaining muddy juice was
precipitated in decanters; filtered with the help of filters. This waste from
the filters is called as “Press Filter Waste (PFW)”. In the experimental study,
mortar samples were obtained by using standard sand, water, sodium silicate (Na2SiO3),
fly ash and PFW in accordance with the literature review performed as
preliminary examination. Fresh and hardened mortar properties were evaluated by
applying unit weight and compressive strength tests depending on different
sieve, curing conditions and water content variables on these mortar samples. Mortar
mixtures were prepared with a sand/binder ratio of 3.0. When the compressive
strength of PFA10T2S2E1 type samples which are activated with the help of 220
ml alkaline activator and have 75 gr water content and fly ash content passed
through 75 µm sieve are evaluated; it has been determined that the compressive
strength of 7-day is 18.53 MPa, 28-day is 19.58 MPa and 56-day is 19.78 MPa.
When the hardened unit weight of the samples were evaluated (28th day), it was
determined that the PFA10T2S2E1 type samples having the highest hardened unit
weight were activated with 220 ml Na2SiO3 alkali
activator and the fly ash was passed through 75 µm sieve and the water content
was 75 gr (1.934 kg/dm3).
