Common lampblack and Venetian red should not be used, as they are apt to run or fade. Dry mineral colors, mixed in proportions of two to ten per cent of the cement, give shades approaching the color used. Red lead should never be used; even one per cent is injurious to the concrete. Variations in the color of cement and...

Today the name "portland" signifies only the kind of cement, not the brand. The manufacture of portland cement was begun in 1825, but the progress was slow until about 1850, when, through improved methods and general recognition of its merits as a building material, its commercial success was assured. Portland Cement in America...
Page 14 - For sands a screen with 30 meshes to the linear inch is necessary to prevent the good particles from passing through it. This must be supported by cleats placed quite near together, or it will break through. The sand is shoveled on to the upper end of the trough by one man, while another one can wash it with a hose. The flow of water will wash the sand down the incline, and as the sand and water pass over the screen the dirty water will drain off through the screen, leaving the clean sand for use....

These are mixed together until the mass shows a uniform color, then water is added and mixed in until the whole is thoroughly...
