The use of recycled materials, such as the fine recycled aggregate made from concrete waste and carbon fiber (CF) product of industrial waste, for the manufacture of conductive recycled mortars (CRM), transforms the mortar base cement normally made with cement:sand in a sustainable multifunctional material, conferring satisfactory mechanical and electrical properties for non-structural uses. This action provides ecological benefits, reducing the use of natural fine aggregates from rivers and the amount of concrete waste deposited in landfills resulting from construction waste. In this investigation the effect of the addition of CF on electrical properties in hardened, wet and dry state, electric percolation in dry state and fluidity of the wet mixture of a cement based CRM was evaluated: fine recycled aggregate: graphite powder, CRM specimens with dimensions of 4 × 4 × 16 cm. were manufactured for 3, 7 and 28 days of age and sand/cement ratios = 1.00, graphite/cement = 1.00, water/cement = 0.60 and CF = 0.1, 0.3, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0% compared to the weight of cement. The results demonstrated the effect of the addition of CF in CRM, reducing fluidity of the mixtures due to the opposition generated by its physical interaction of CF with recycled sand or recycled fine aggregate and graphite powder (GP), in its case, placing the electric percolation percolation at 0.30% and 0.45% of CF for CRM with and without GP, respectively. Increases in electrical conductivity (EC) without the presence of GP are defined by the contact between the CF and the conductive paths formed. In contrast, with the presence of GP, the EC is defined by the contact between the CF and the GP simultaneously, forming conductive routes with greater performance in its EC.

使用再生材料，例如由混凝土废料和工业废料的碳纤维（CF）产品制成的细粒再生集料，来制造导电再生砂浆（CRM），可以将通常用水泥制成的砂浆基础水泥进行转化：一种可持续的多功能材料，可为非结构性用途提供令人满意的机械和电气性能。此举带来了生态效益，减少了河流天然细骨料的使用，并减少了建筑废料在垃圾填埋场沉积的混凝土废料的数量。在这项研究中，添加CF对硬化，湿和干态下的电性能，干态下的电渗滤以及水泥湿混合物的流动性的影响基于CRM的产品进行了评估：精细的回收骨料：石墨粉，CRM标本的尺寸为4×4×16 cm。分别针对3、7和28天的年龄进行制造，沙/水泥比= 1.00，石墨/水泥= 1.00，水/水泥= 0.60，CF = 0.1、0.3、0.5、1.0、1.5、2.0、2.5和3.0％水泥的重量。结果表明，在CRM中添加CF的效果降低了混合物的流动性，这是由于CF与再生砂或再生细骨料和石墨粉（GP）发生物理相互作用而产生的反作用力。有和没有GP的CRM分别在CF的0.30％和0.45％处发生渗滤。在不存在GP的情况下，电导率（EC）的增加由CF与所形成的导电路径之间的接触确定。相反，如果有GP，
