A host of emerging cementitious products derived from waste materials or sustainable precursors have drawn increasing interest in response to economic, social and regulatory pressures. Among the more well-studied and abundant of such cement products are sulfur cements and pozzolans like fly ash, silica fume, ground granulated blast furnace slag, and metakaolin. For the current study, oleic acid was combined with these compounds to make a series of pastes. Oleic acid is an attractive additive because it is a primary constituent of low value, high-volume by-products of biodiesel production and animal product rendering. The current work is thus a comparative study of pastes prepared by heating sulfur and oleic acid with either ordinary Portland cement or one of the pozzolan-extended cements. The mechanical properties of the cured sulfur-oleic acid pastes were assessed by dynamic mechanical analysis to provide stress-strain curves both before and after acid challenge. All of the blocks prepared from the pastes retain significantly more mechanical strength (up to 100%) after exposure to strong oxidizing acid solutions than does ordinary Portland cement. Surface damage to these sulfur cement blocks can be healed to varying extents by thermal annealing, as assessed by optical microscopy.

应对经济，社会和法规压力，从废料或可持续的前体衍生的许多新兴水泥产品引起了越来越多的兴趣。在这类水泥产品中，经过深入研究和丰富的产品包括硫磺水泥和火山灰，如粉煤灰，硅粉，磨碎的高炉矿渣和偏高岭土。在当前的研究中，油酸与这些化合物混合制成一系列糊状物。油酸是一种有吸引力的添加剂，因为它是生物柴油生产和动物产品提炼的低价值，大批量副产品的主要成分。因此，目前的工作是对糊料的比较研究，该糊料是通过将硫和油酸与普通硅酸盐水泥或火山灰扩展水泥中的一种进行加热而制备的。通过动态力学分析评估硫化硫油酸糊的机械性能，以提供酸激发前后的应力-应变曲线。由糊料制成的所有块料在暴露于强氧化性酸溶液后仍比普通波特兰水泥具有更高的机械强度（高达100％）。如光学显微镜所评估的，可以通过热退火在不同程度上治愈对这些硫磺水泥块的表面损害。
