摘要:
工业固废磷石膏（PG）大量堆存造成环境问题，又因其力学性能不足、耐水性差的缺陷，导致资源化利用受限。为实现PG高值化利用，以PG和矿渣为主要原料，分别采用硅酸盐水泥（OPC）、硫铝酸盐水泥（SAC）搭配钢渣、氢氧化钙为碱性激发剂改善其力学性能，并在此基础上利用有机硅憎水剂增强其耐水性，制备免烧PG矿渣行道砖。实验方法包括吸水率与软化系数实验、冻融循环实验及防滑性能实验。结果表明，水泥类型显著影响耐水性，OPC体系仅O-1、O-2组满足国标要求；SAC体系各组均达标。有机硅憎水剂最佳掺量为1%，S-1-1组耐水性最优，吸水率0%，软化系数1.55。抗冻防滑测试中，S-1~S-3及O-2组满足D25等级与防滑要求，S-2-1组摆式仪测定值（BPN）达74，防滑最优，S-1-1强度损失率仅3%，抗冻性最佳。
Abstract:
The large-scale stockpiling of phosphogypsum (PG), an industrial solid waste, causes environmental problems, and its subpar mechanical properties and poor water resistance restrict its resource utilization. To achieve high-value utilization of PG, PG and slag were used as the main raw materials to make PG-slag paving bricks. Silicate cement (OPC) and sulphaluminate cement (SAC) were respectively combined with steel slag and calcium hydroxide (as alkaline activators) to improve mechanical properties, while organosilicon water-repellent was added to enhance water resistance, thus preparing non-baked PG-slag paving bricks. Experimental methods included water absorption , softening coefficient, freeze-thaw cycle and anti-slip performance tests. Results showed that cement type had a significant impact on water resistance: only groups O-1 and O-2 in the OPC system met national standards, while all groups in the SAC system met the requirements. The optimal dosage of organosilicon water-repellent was 1%, and the S-1-1 group had the best water resistance with 0% water absorption and 1.55 softening coefficient. In the freeze-thaw and anti-slip tests, groups S-1 to S-3 and O-2 met the D25 grade and anti-slip requirements. The S-2-1 group had the best anti-slip performance with a BPN value of 74, and the S-1-1 group had the best frost resistance with a strength loss rate of only 3%.
