摘要：In recent years, magnesium oxychloride cement (MOC) has drawn more and more attention, but its disadvantages of poor water resistance, brittleness, easy to absorb moisture limited its uses. Waste glass fiber reinforced plastic (GFRP) and additives were added into the MOC to improve its performance. The results show that waste GFRP fiber with the length of 5-10 mm has remarked contribution to the softening coefficient of the cement paste. When the addition is 2%, the softening coefficient of the cement increases by 24.95%. Compared to the blank, proper dosages of phosphoric acid, ferric phosphate and citric acid increase the softening coefficient of MOC from 0.461 to 1.026, 0.797 and 0.993 respectively.
