High-specific-gravity bridge counterweight concrete and preparation method thereof
The invention provides high-specific-gravity bridge counterweight concrete. The high-specific-gravity bridge counterweight concrete is prepared from cement, matte iron, recycled slag-containing iron particles, gilding powder and water. The preparation method comprises the following steps: (1) mixing cement and matte iron to obtain a cementing material; (2) recycled slag-containing iron particles, gilding powder and part of the gilding material obtained in the step (1) are mixed and stirred, then water and the remaining gilding material obtained in the step (1) are added, stirring is conducted, and mixed slurry is obtained; (3) injecting the mixed slurry obtained in the step (2) into a mold, and vibrating and compacting to obtain a concrete test block; and (4) curing the concrete test block obtained in the step (3) along with the mold. The prepared counterweight concrete is good in compressive strength and large in apparent density.
本发明提供一种高比重桥梁配重混凝土，包括如下原料：水泥、冰铜铁、回收含渣铁粒、鎏金粉、水；制备方法，包括如下步骤：(1)将水泥和冰铜铁混合，得到胶凝材料；(2)将回收含渣铁粒、鎏金粉和部分步骤(1)得到的胶凝材料混合，搅拌，随后加入水和剩余的步骤(1)得到的胶凝材料，拌和，得到混合浆料；(3)将步骤(2)得到的混合浆料注入模具，振动压实，得到混凝土试块；(4)将步骤(3)得到的混凝土试块随模具养护，即得。本发明制得的配重混凝土抗压强度佳，表观密度大。
