Abstract

The sustainability in civil engineering is supported by ecological awareness. Several efforts have been done to achieve sustainability of civil engineering, such as introducing green admixture for concrete. The research tries to deliver a low dosage of sucrose as admixture, 0.03% of cement weight that is becomes ingredient of concrete mixture. The research conducts experiment methods and uses specimens consists of some mortar cubes and concrete cylinders specimens with compressive strength design MPa. The variant of specimens is divided into plain and added by sucrose 0.03% of cement weight. All specimens are cured for 7, 14, and 28 days, and then tested for its compressive strength. The experiment also conducts an observation of mortar surface hardening by trinoculer electronic microscope. This research meets conclusions as follow: (1) Sucrose with low dosage of 0.03% of cement weight can prohibit the hardening of cement paste; (2) The sucrose admixture with dosage of 0.03% by weight of cement for mortar specimens performs as accelerator because its values of compressive strength at days-14 and 28 are 7-17% higher than plain mortar; (3) The sucrose admixture with dosage of 0.03% by weight of cement for concrete specimens perform as retarder because its values of compressive strength at days-7 and 14 are 11-27% lower compared to plain concrete; (4) The sucrose admixture with dosage of 0.03% by weight of cement for concrete specimens increases the compressive strength, 26% higher than plain concrete; (5) In the first 6 hours of mortar hardening, the presence of sucrose with low dosage of 0.03% of cement weight is giving retardation effect that the surface of mortar specimens is wetter and softer compared to the plain mortar; and (6) The performance of sucrose as retarder and accelerator green admixture will fulfil the need of sustainability of civil engineering.
