For uniform color, white cement concrete mixes should be rich in cement, with a high fine-sand content and continuously graded coarse aggregate to promote a more uniform appearance. A high proportion of fine aggregate is recommended to reduce color variation. Because the sand acts like a pigment in the mix, its color is important. White or lightcolored sands give the best results for bright white concrete or pastel finishes. If natural sands are not available or are not the right color, manufactured sands are a good alternative.

A fresh mixture having a slump of about 100 mm (4 in.) works well for many projects. Admixtures, including water reducers and air-entraining chemicals, can provide added workability. Regardless of temperature fluctuations or other changing weather conditions, proportions for white and colored concrete should be held constant. Modifying the concrete mixture by changing materials, proportions, or construction procedures could lead to color differences.
