Abstract

One of the important steps in the production of geo-polymer concrete is the curing process, because temperature and duration of curing affect the compressive strength of the geo-polymer concrete. This study aims to determine the effect of steam curing temperature and duration on the compressive strength of geo-polymer concrete. All concrete specimens are cylinders with diameter of 15 x 30 cm cured with the steam. The steam temperatures will be controlled from 60 0C, 70 0C, 80 0C, 90 0C and 100 0C and the duration of curing will vary1 hour to 4 hours. In order to have the normal concrete strength the authors used the mix design of geo-polymer concrete based on the activator solution consist of Sodium Hydroxide (NaOH) 6 Molarity and Sodium Silicate gel (Na2SiO3). The specimens were tested for compressive strength test at the age of 28 days. It can be concluded that the right steam curing method and equipment could increase the compressive strength of geo-polymer concrete up to 100 % compared the concrete specimens cured in the room temperature.
