dc.description.abstractIn this study, heat curing technique (up to 320 degrees C) that allows the usage of sodium silicate solutions with un-calcined kaolins to offer a durable geopolymeric binder in a short time was investigated. Samples containing up to 40 wt.% binder have been produced to observe the binder behaviour over a wide range of additions by heat curing for one hour. The cured samples consist of kaolinite and amorphous phase and crystallinity was decreased with increasing curing temperatures. 240 degrees C was the threshold temperature for the strength development of the samples. Condensation reactions between Al-OH- units in uncalcined kaolin and silanol groups in sodium silicate solution that yield sialate (Si-O-Al-O) bridges detected by infrared analyses are the considered mechanisms of promoter effects of kaolinite. Optimum compressive strength (23.4 MPa.) was obtained with the samples produced with 20 wt.% binder addition and 300 degrees C curing temperature.en_US
