研究了激发剂种类、模数、掺量等因素对矿渣基地聚合物早期力学性能的影响。研究结果表明:相对于Na2Si O3,K2Si O3对矿渣基地聚合物具有显著的激发效果;激发剂模数及掺量对矿渣基地聚合物早期抗压强度具有显著影响,随着激发剂模数提高,矿渣基地聚合物早期抗压强度增加明显,随着激发剂掺量提高,矿渣基地聚合物早期抗压强度先提高后降低,在掺量为12%时,材料具有最高抗压强度;激发剂模数及掺量的变化对矿渣基地聚合物的抗折强度影响不大,且随着激发剂掺量的增加,矿渣基地聚合物的折压比呈下降的趋势,材料脆性变大。
The effects of the kinds of activators, moduli and dosages on the early mechanical properties of slag-based polymers were investigated. The results show that K2SiO3 has significant effect on the slag base polymer compared with Na2SiO3. The modulus and content of the initiator have a significant effect on the early compressive strength of slag base polymer. With the increase of the modulus of activator, The early compressive strength of the slag base polymer increases obviously. With the increase of the dosage of the activator, the compressive strength of the slag base polymer first increases and then decreases. When the dosage is 12%, the material has the highest compressive strength. The change of the number and the content of the slag base polymer had little effect on the flexural strength of the slag base polymer. With the increase of the dosage of the activator, the pressure-reducing ratio of the polymer in the base slag decreased, and the brittleness of the material became larger.
