High-organic-matter high-salt sludge curing agent and application thereof
The invention provides a high-organic-matter high-salt sludge curing agent and application thereof, and relates to the field of hydraulic cementing materials and application thereof. The high-organic-matter high-salt sludge curing agent comprises the following components in percentage by weight: 10-45% of cement clinker, 15-50% of slag, 10-20% of carbide slag, 5-25% of a filling material, 1-3% of calcium carbonate, 1-5% of an expanding agent and 0.2-1% of a thickening time control agent, and the filling material comprises stone powder, silty-fine sand, high-calcium fly ash and the like; the expanding agent comprises gypsum, desulfurized gypsum and the like; the thickening time control agent comprises carboxymethyl cellulose sodium, calcium lignosulphonate, sodium hexametaphosphate and the like. The sludge curing agent needs a certain amount of cement clinker as an exciting agent, so that various raw materials play a role, and PO42.5 cement can be used for replacing the raw materials in specific construction. After the soft soil curing agent disclosed by the invention is applied, peat soil or a high-salt-content stratum and other soil layers with a poor cement reinforcing effect can have relatively good physical and mechanical properties.
本发明提供一种高有机质高盐淤泥固化剂及其应用，涉及水硬性胶凝材料及其应用领域。该一种高有机质高盐淤泥固化剂，包括如下重量百分比的组分：10～45％水泥熟料、15～50％矿渣、10～20％电石渣、5～25％充填材料、1～3％碳酸钙、1～5％膨胀剂、0.2～1％调凝剂，所述充填材料包括石粉、粉细砂、高钙粉煤灰等；所述膨胀剂包括生石膏、脱硫石膏等；所述调凝剂包括羟甲基纤维素钠、木质素磺酸钙盐、六偏磷酸钠等。淤泥固化剂中需有一定量的水泥熟料做为激发剂，使各种原料发挥作用，具体施工中可用PO42.5水泥代替。本发明软土固化剂的应用后能使泥炭质土或高含盐地层等水泥加固效果差的土层具有较好的物理力学性能。
