Self-leveling mortar (SLM) is a special mortar that can flow and fill under its own weight without the need for any compaction energy. To meet these characteristics and to ensure their stability (no segregation and exudation) these mortars require, in addition to proper mixing design and the use of water reducing assets, a large quantity of fines or viscosity modifying additives, which raises the cost for the production. The use of industrial by products such as sugar-cane bagasse ash (SCBA) is an interesting alternative because they are lower cost materials and act as viscosity modifying agent, providing improvements in the rheological, physical and mechanical properties for SLM. Thus, the influence of SCBA on the rheological, physical and mechanical properties of cement-based and limestone filler (LF) mortars will be investigate in this research. The mortars were produced with a water/binder (cement + LF + SCBA) volumetric ratio of 0.85 and 15%, 20%, 25% and 30% Portland cement (PC) replacement by SCBA. An experimental study was conducted to evaluate the effects of SCBA incorporation on the properties of fresh (viscosity, flowability and filling ability) and hardened mortars (flexural strength, compressive strength, dynamic modulus of elasticity, bond strength and water absorption by capillarity). The results show that the rheological, physical and mechanical behavior of mortars was improved, especially for contents of up to 25% replacement of PC by SCBA. For higher contents, the performance of SLM was reduced.

自流平砂浆（SLM）是一种特殊的砂浆，可以在其自身重量下流动和填充，而无需任何压实能量。为了满足这些特性并确保其稳定性（不偏析和渗出），这些砂浆除了需要适当的混合设计和使用减水剂外，还需要大量的细粉或增粘剂，这增加了生产成本。使用工业副产品（例如甘蔗渣蔗糖灰（SCBA））是一种有趣的替代方法，因为它们是成本较低的材料，并充当粘度调节剂，从而改善了SLM的流变，物理和机械性能。因此，本研究将研究SCBA对水泥基和石灰石填料（LF）砂浆的流变，物理和机械性能的影响。砂浆的水/粘合剂（水泥+ LF + SCBA）的体积比为0.85，用SCBA代替15％，20％，25％和30％的硅酸盐水泥（PC）。进行了一项实验研究，评估了SCBA掺入对新鲜砂浆（粘度，流动性和填充能力）和硬化砂浆（抗折强度，抗压强度，动态弹性模量，粘结强度和毛细吸水率）的影响。结果表明，砂浆的流变，物理和机械性能得到了改善，特别是当SCBA替代PC含量高达25％时。对于更高的内容，SLM的性能会降低。进行了一项实验研究，评估了SCBA掺入对新鲜砂浆（粘度，流动性和填充能力）和硬化砂浆（抗折强度，抗压强度，动态弹性模量，粘结强度和毛细吸水率）的影响。结果表明，砂浆的流变，物理和机械性能得到了改善，特别是当SCBA替代PC含量高达25％时。对于更高的内容，SLM的性能会降低。进行了一项实验研究，评估了SCBA掺入对新鲜砂浆（粘度，流动性和填充能力）和硬化砂浆（抗折强度，抗压强度，动态弹性模量，粘结强度和毛细吸水率）的影响。结果表明，砂浆的流变，物理和机械性能得到了改善，特别是当SCBA替代PC含量高达25％时。对于更高的内容，SLM的性能会降低。改善了砂浆的物理和机械性能，特别是对于SCBA替代PC含量高达25％的砂浆而言。对于更高的内容，SLM的性能会降低。改善了砂浆的物理和机械性能，特别是对于SCBA替代PC含量高达25％的砂浆而言。对于更高的内容，SLM的性能会降低。
