Barite counterweight concrete and preparation method thereof
The invention relates to the field of anti-radiation building materials, in particular to barite counterweight concrete and a preparation method thereof. The barite counterweight concrete is prepared from a concrete mixture, the concrete mixture comprises water, Portland cement, coal ash, mineral powder, fine aggregate, barite and an efficient retarding and water reducing agent, wherein the fine aggregate comprises common sand and heavy crystal sand. The preparation method comprises the following steps: a) uniformly mixing barite, coal ash, mineral powder and fine aggregate, and adding water until the surfaces of the raw materials are wetted by water to obtain a premix; b) adding Portland cement into the premix, and uniformly mixing the components to obtain a medium mixture; c) adding the high-efficiency retarding and water reducing agent and the residual water into the medium mixture, and uniformly stirring the components to obtain a finished product. The product provided by the invention has the advantage of improving the anti-radiation capability of concrete.
本申请涉及防辐射建筑材料领域，更具体地说，它涉及一种重晶石配重混凝土及其制备方法。一种重晶石配重混凝土，其特征在于，由混凝土拌合料制备而成，混凝土拌合料包括水、硅酸盐水泥、煤灰、矿粉、细骨料、重晶石、高效缓凝减水剂；其中，细骨料包括普通砂和重晶砂；其制备方法为：步骤a)：将重晶石、煤灰、矿粉、细骨料混合均匀，加水直至各种原料表面呈现被水润湿的状态，得到预混料；步骤b)：往预混料内加入硅酸盐水泥，混合均匀，得到中混料；步骤c)：往中混料内加入高效缓凝减水剂、剩余水，搅拌均匀，得到成品。本申请的产品具有提高混凝土的防辐射能力优点。
