Abstract
Admixture takes an important role to improve physical and economic benefits with respect to concrete and mortar. Previous researches concluded that sugar based admixture such as sugar, sucrose, sugar cane liquid, perform as accelerator and retarder with dosages of 0.03% and 0.3% by weight of cement. The composition of those three components (sugar, sucrose, sugar cane liquid) in one mix then being investigated to improve the compressive strength of mortar. There are 16 compositions to be investigated with designed compressive strength of mortar 30 MPa.The specimens are tested for ages of 7 days, 14 days, and 28 days. The research meets conclusions : (1) Chemical test of ingridients of sugar based admixture gives result that all ingridients contain lignin of about 0.175%-0.186% while the highest glucose content found in sugar cane liquid, 76.933%, followed by sugar 76.738%. It means that sugar and sugar cane liquid will affect the performance of mortar hardening, (2) There are 6 optimum compositions. Five composition then perform accelerating action that increase the compressive strength in early ages and one composition performs retarding action which slowing the compressive strength growth in early ages; (3) The low content of sugar and sugar cane liquid will contribute rapid growth of calcium silicate hydrates and enrich bond mechanisme of hardening mortar while high content of sucrose, sugar and sugar cane liquid, will make growth of calcium silicate hydrates slower and then retard the bond mechanisme of hardening mortar; (4) The optimum compositions of sugar based admixture consists of sucrose, sugar and sugar cane liquid mix could become reference for designing concrete that also have high performance of compressive strength.
