The incorporation of fly ash from olive biomass (FAOB) combustion in cogeneration plants into cement based mortars was explored by analyzing the chemical composition, mineralogical phases, particle size, morphology, and IR spectra of the resulting material. Pozzolanic activity was detected and found to be related with the presence of calcium aluminum silicates phases. The preparation of new olive biomass fly ash content mortars is effective by replacing either CaCO(3) filler or cement with FAOB. In fact, up to 10% of cement can be replaced without detracting from the mechanical properties of a mortar. This can provide an alternative way to manage the olive biomass fly ash as waste produced in thermal plants and reduce cement consumption in the building industry, and hence an economically and environmentally attractive choice.
研究了将橄榄生物质（FAOB）燃烧产生的粉煤灰掺入热电厂灰渣水泥基砂浆中，通过分析所得材料的化学组成、矿物相、粒度、形态和红外光谱。检测到了火山灰活性，发现与钙铝硅酸盐相的存在有关。用 FAOB 替代 CaCO(3)填料或水泥来制备新的橄榄生物质粉煤灰含量砂浆是有效的。事实上，在不降低砂浆力学性能的情况下，10%的水泥可以被替代。这为管理热电厂产生的橄榄生物质粉煤灰这一废弃物提供了一种替代方法，同时减少了建筑行业对水泥的消耗，因此是一种经济和环境都具有吸引力的选择。
