Environment-friendly concrete capable of absorbing electromagnetic waves and preparation method thereof
The invention discloses environment-friendly concrete capable of absorbing electromagnetic waves, and relates to the technical field of concrete preparation, the environment-friendly concrete is composed of the following components in parts: 15-20 parts of cement, 10-12 parts of water, 6-8 parts of an admixture solution, 60-65 parts of aggregate and 5-9 parts of an admixture, the admixture solution comprises an early strength agent, an air entraining agent and an antifreezing agent, the aggregate comprises coarse aggregate and fine aggregate, and the coarse aggregate and the fine aggregate are uniformly mixed. And the material of the admixture is composed of low-calcium fly ash. The early strength agent, the air entraining agent and the anti-freezing agent are added into the concrete raw materials, the early strength agent can improve the early strength of the concrete, the air entraining agent generates chemical reaction and releases gas in the concrete preparation process, so that a large number of air holes are formed in the concrete, and the anti-freezing agent can harden the concrete at negative temperature; the anti-electromagnetic wave capability of the concrete can be effectively improved by adding the coarse aggregate and the fine aggregate, so that the concrete has the advantage that the strength and the anti-electromagnetic wave capability of the concrete can be conveniently improved.
本发明公开了一种吸收电磁波环保混凝土，涉及混凝土制备技术领域，由以下份数的成分组成，水泥15～20份，水10～12份，外加剂溶液6～8份，骨料60～65份，外掺混合料5～9份，外加剂溶液包括有早强剂、加气剂和防冻剂，所述骨料包括有粗骨料和细骨料，所述外掺混合料的材料由低钙粉煤灰组成。本发明通过往混凝土原料中加入早强剂、加气剂和防冻剂，早强剂能够提高混凝土早期强度，加气剂在混凝土制备过程中发生化学反应，放出气体，使混凝土中形成大量气孔，防冻剂能够使混凝土在负温下硬化，并在规定时间内达到足够防冻的强度，通过加入的粗骨料和细骨料能够有效增加混凝土的抗电磁波能力，具有方便增加混凝土的强度和抗电磁波能力的优点。
