Grounding conductive concrete and preparation method thereof
The invention discloses grounding conductive concrete and a preparation method thereof. The grounding conductive concrete is prepared from the following raw materials in parts by mass: 80-150 parts ofcement, 110-200 parts of fine aggregate, 260-350 parts of coarse aggregate, 30-70 parts of water, 0.5-4 parts of carbon fibers and 1-4 parts of a water reducing agent. The carbon fiber with excellentconductivity is used as a conductive phase material of the concrete, the materials can be fully mixed without adding a dispersing agent and a defoaming agent through cooperation with the innovative mixing method, agglomeration of carbon fibers is effectively avoided, and agglomeration can also be effectively avoided even if high carbon fibers are doped so that the materials are fully mixed and dispersed; the synergistic effect among the innovative materials can be further exerted; the conductive performance, the resistance stability and the mechanical strength of the concrete can be greatly improved, the preparation process is simplified, the requirements of the tower grounding material on the conductive performance, the resistance stability and the mechanical strength can be met when themixing amount of the carbon fibers is very low and the using amount of cement is relatively low, and the manufacturing cost is reduced.
本发明公开了一种接地导电混凝土及其制备方法，按照质量份数比由以下原料组成：水泥80～150份、细集料110～200份、粗集料260～350份、水30～70份、碳纤维0.5～4份、减水剂1～4份。本发明采用具有优越导电性碳纤维为混凝土的导电相材料，配合本发明创新的拌和方法，可在无需添加分散剂和消泡剂的前提下，即可使物料充分拌和，有效避免碳纤维的团聚，即使在较高的碳纤维掺入下，也能有效避免团聚，使物料充分拌和分散；可进一步发挥所述的创新物料之间的协同效果，可以大大提升混凝土的导电性能、电阻稳定性和机械强度，简化了制备工艺，且碳纤维掺量很低和水泥用量较低时即能满足杆塔接地材料对导电性能、电阻稳定性和机械强度要求，降低了制造成本。
