Abstract

Comparison of the influence of amino trimethylene phosphonic acid (ATMP) and sodium gluconate (SG) on the performance of concrete are investigated in this paper. The comparison of the effects of ATMP and SG on concrete setting time at 20°C or 35°C, concrete slump loss, concrete compressive strength and cement pastes dry shrinkage are investigated. The results show that the retard effect of ATMP is much stronger than SG at 20°C and the dosage is higher the retard effect is obvious, the “temperature adaptability” of SG is much worse than ATMP; SG and ATMP both have the “auxiliary water reducing effect” and “slump loss resistant effect”, nevertheless the “slump loss resistant effect” of ATMP is better than SG; the development rate of concrete early age compressive strength within ATMP is slow than the concrete within SG, but the concrete later strength within ATMP will exceed the blank concrete and the concrete within SG at the dosage range from 0.06% to 0.15%; the relationship of cement paste dry shrinkage is ATMP SG.
