The invention relates to the field of grouting, and particularly discloses a fly ash modified double-liquid grouting material. The fly ash modified double-liquid grouting material comprises a group A material, a group B material and disodium hydrogen phosphate, the material group A comprises cement, fly ash and water, the weight part of the fly ash is 0-60, and the weight determination of the cement, the fly ash and the water comprises the following steps: step 1, calculating the weight ratio of the water to the cement according to the formula: the water-binder ratio = the weight of the water/(the weight of the cement + the weight of the fly ash), and the water-binder ratio of the material group A is 0.6-0.8; 2, when the weight part of the fly ash is larger than 0, the mixing amount of the fly ash accounts for 45-55% of the total weight of the fly ash and the cement; the material group B comprises water glass, and the baume degree of the water glass in the prepared fly ash modified double-liquid grouting material is 40-53; the weight of the disodium hydrogen phosphate is 0-3% of the total weight of the cement and the fly ash. The fly ash modified double-liquid grouting material provided by the invention is smaller in particle size, and meanwhile, the durability of the grouting material is improved.
本发明涉及注浆领域，具体公开了一种粉煤灰改性双液注浆材料。一种粉煤灰改性双液注浆材料，包括A组材料、B组材料和磷酸氢二钠；A组材料包括水泥、粉煤灰和水，粉煤灰的重量份为0～60份，水泥、粉煤灰和水的重量确定包括以下步骤：步骤1：根据公式：水胶比＝水的重量/(水泥的重量+粉煤灰的重量)，计算出水与水泥之间的重量比例，A组材料的水胶比为0.6～0.8；步骤2：粉煤灰的重量份大于0时，粉煤灰的掺量为粉煤灰与水泥之间的总重量的45～55％；B组材料包括水玻璃，制备的粉煤灰改性双液注浆材料中的水玻璃波美度为40～53；磷酸氢二钠的重量为水泥和粉煤灰总重量的0～3％。本发明中的粉煤灰改性双液注浆材料的颗粒粒径更小，同时提高注浆材料的耐久性。
