Abstract

The present research studies the effect of adding sugar factory waste sugarcane molasses as an alternative to chemical inhibitory additives manufactured on concrete cast during hot weather in the summer of Iraq. The current study includes a study of the setting time for cement paste and workability for fresh concrete and some mechanical properties of hardened concrete with sugarcane molasses using percentage 0–0.3% of cement weight. The study also included studying the value of pH of concrete to investigate the effect of sugarcane molasses on reinforced concrete. The results showed that the sugarcane molasses can be used by about 0.1% of cement weight for medium projects and between 0.1 and 0.2% for large projects. It was also found that the compression strength increased by about 11.5% and the indirect tensile strength increased by about 7.5 and 7.4% for splitting and flexural test, respectively for concrete mixtures containing 0.2% of sugarcane molasses.

高温天气下混凝土中甘蔗糖蜜的性能

本研究探讨了在伊拉克夏季的炎热天气中，添加糖厂废料甘蔗糖蜜作为化学抑制添加剂的替代品对混凝土浇注的影响。本研究包括对水泥浆凝结时间和新拌混凝土工作性的研究，以及使用甘蔗糖蜜（占水泥重量的 0-0.3%）硬化混凝土的一些机械性能。研究还包括混凝土的 pH 值，以探讨甘蔗糖蜜对钢筋混凝土的影响。结果表明，中型工程可使用水泥重量 0.1%左右的甘蔗糖蜜，大型工程可使用 0.1%至 0.2%的甘蔗糖蜜。研究还发现，含 0.2%甘蔗糖蜜的混凝土混合物的抗压强度提高了约 11.5%，劈裂和弯曲试验的间接抗拉强度分别提高了约 7.5%和 7.4%。
