Building material made of shield muck, baking-free brick made of shield muck and preparation method of baking-free brick
The invention provides a building material made of shield muck, a baking-free brick made of shield muck and a preparation method of the baking-free brick, and the building material made of shield muck comprises the following components in percentage by mass: 70-90% of original shield muck, 6-20% of cement and 4-10% of a curing agent, the curing agent comprises the following components in percentage by mass: 50-85% of blast furnace water granulated slag, 5-15% of semi-hydrated gypsum, 7-20% of calcium aluminate, 1-5% of alum, 2-10% of quick lime and 1-5% of fiber. The curing agent composed of the blast furnace water slag, the semi-hydrated gypsum, the calcium aluminate, the alum, the quick lime and the fiber mixture in a specific proportion is adopted to have a synergistic effect with the original-state shield muck, the cement and the water, so that the curing agent has excellent mechanical properties; the utilization rate of the undisturbed shield muck can be increased, and the cost and risk of the undisturbed shield muck in the recovery process are reduced.
本申请提供了一种盾构渣土制建筑材料、盾构渣土制免烧砖及其制备方法，该盾构渣土制建筑材料按质量百分比计包括：原状盾构渣土70～90％、水泥6～20％、固化剂4～10％，其中，固化剂的组分按质量百分比计如下：高炉水渣50～85％、半水石膏5～15％、铝酸钙7～20％、明矾1～5％、生石灰2～10％和纤维1～5％。通过采用特定配比的高炉水渣、半水石膏、铝酸钙、明矾、生石灰和纤维混合物组成的固化剂与原状盾构渣土、水泥和水相互协同作用，该固化剂具有优异的力学性能，能够提高原状盾构渣土的利用率、降低原状盾构渣土在回收过程中的成本和风险。
