目前,生产彩色水泥的一般方法都是在普通水泥或白水泥中掺加适量的颜料,均匀拌合而成。这样制得的彩色水泥颜色不均匀、不稳定。苏联П·И·勃任诺夫提出一种制造彩色水泥的新方法。即在低铁的生料中掺加极少量(1%以下)的金属氧化物(铬、锰和钴等的氧化物),使染色氧化物渗入矿物晶格或与矿物生成固溶体。这样制得的彩色水泥就不是水泥和颜料的机械混合物,而是颜料和熟料矿物结合在一起,所以颜色比较均匀和稳定。试验时所用的颜料有铬、锰、钴、镍、 At present, the general method for producing colored cement is to add proper amount of pigment to ordinary cement or white cement and evenly mix them together. The color cement thus obtained is uneven in color and unstable. The Soviet Union П. I. Bozenov proposed a new method of manufacturing colored cement. That is, a very small amount (less than 1%) of metal oxide (oxides such as chromium, manganese, and cobalt) is added to the low-iron raw material, so that the dyed oxide penetrates into the mineral lattice or forms a solid solution with the mineral. The colored cement thus obtained is not a mechanical mixture of cement and pigment, but the pigment and the clinker mineral are combined so that the color is relatively uniform and stable. The test pigments used are chromium, manganese, cobalt, nickel,
