Counterweight concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to counterweight concrete and a preparation method thereof. The counterweight concrete provided by the invention comprises the following components in percentage by mass: 3-7% of cement; 2.2-5.1% of water; 50.1-90.7% of an aggregate; and 4.1-37.8% of high-density aggregate. According to the filling volume and the balance weight requirement, the adding amount of the cement, the water, the low-density aggregate and the high-density aggregate is reasonably determined, and different balance weight density requirements are met; by reducing the proportion of the cement, increasing the proportion of the low-density aggregate and reducing the proportion of the high-density aggregate, the economic cost is greatly reduced, and the problems of environmental pollution and energy consumption caused by smelting of the high-density aggregate are relieved. Tests show that the compressive strength of the concrete provided by the invention reaches C15, and vibration tests show that the strength requirement of counterweight concrete in the field of engineering machinery is met.
本发明属于混凝土技术领域，具体涉及一种配重混凝土及其制备方法。本发明提供的配重混凝土，包括如下质量百分含量的组分：水泥3－7％；水2.2－5.1％；集料50.1－90.7％；高密度骨料4.1－37.8％。本发明根据填充容积大小和配重要求，合理确定水泥、水、低密度集料和高密度骨料的加入量，满足不同配重密度要求；通过降低水泥占比，提高低密度集料占比，降低高密度骨料占比，大大降低了经济成本，缓解了高密度骨料需要冶炼带来的环境污染和能耗问题。经测试，本发明提供的混凝土抗压强度达到C15，通过振动试验，满足工程机械领域配重混凝土的强度要求。
