Weathered basalt (WB) is a useless and costless material with a negative environmental impact. The use of WB to replace clay in Portland clinker manufacturing is a successful strategy to enhance clinker quality, cost and reduce environmental impact. In this study, four mixes were prepared by replacing clay with 25, 50, 75 and 100 wt% of WB (M₁-M₄, respectively) keeping the ratio of the other mix constituents (limestone, sand and iron ore) constants. Another mix (M₅) was prepared using 100% WB, with increasing sand percent and deduction iron ore content. The major innovation presented in M₅ is the possibility to make a substitution of clay and iron ore with WB. This allows for much higher levels of mixture cost reduction. WB allows higher levels of substitution down of the number of raw mix components and improvement in burnability. Also promotes the formation of main clinker phases, especially alite phase.

风化玄武岩（WB）是无用且无价的材料，会对环境造成负面影响。在波特兰熟料生产中，使用WB代替粘土是提高熟料质量，成本和减少环境影响的成功策略。在这项研究中，通过用25、50、75和100 wt％的WB（分别为M ₁ -M ₄）代替粘土来制备四种混合物，同时保持其他混合物成分（石灰石，沙子和铁矿石）的比率不变。使用100％WB制备了另一种混合物（M ₅），同时增加了砂百分比并减少了铁矿石含量。M _5中的主要创新用WB替代粘土和铁矿石的可能性。这允许更高水平的混合物成本降低。WB允许更高水平的替代，减少了原料混合物组分的数量，并提高了可燃性。还促进了主要熟料相的形成，尤其是阿利特相。
