Sugar-factory lime sludge had a more favorable influence in improving the structure of acid soils than limestone. 糖厂的石灰沉渣,在改良酸性土结构上,要比石灰石粉有更良好的影响。
The workability and compressive strength of concrete containing super-fine limestone powder and titanium slag powder were studied. 研究了超细石灰石粉单掺及其与钛矿渣粉复掺对混凝土工作性能及抗压强度的影响。
