Clean equipment in good condition should be used to mix white cement concrete. All contaminants must be prevented, including oil, grease, and dirt, and unless a truck mixer will be used exclusively for white or colored concrete, extra care should be taken to remove all loose gray cement concrete that may be in the mixer drum. For small projects, mobile batchers can be used.

Overall, mixing white concrete is like mixing any other concrete. Generally, the coarse aggregate is added first, along with part of the mix water. This is followed by cement, sand, pigment (if any), and more water. Some of the water can be held back to adjust the batch toward the end of mixing. Admixtures can be added along with the mixing water. If more than one admixture is used, check with the supplier to make certain they are compatible.

To achieve uniform blending, slightly longer mixing times may be required, especially if using water-resistant white cement. The mixing time must be sufficient to obtain a uniform dispersion of the cement throughout the mixture. There are several reasons why this is important. Dispersion affects color. Higher-than-normal cement contents require longer-than-typical mixing times. Furthermore, white cements are ground slightly finer than common gray portland cements. The finer size of the particles means that rigorous mixing—by slightly extending the mixing time—is needed to blend the cement with the other ingredients. Mixing time from batch to batch should be constant. Variable mixing might cause different degrees of dispersion, especially if pigments are being used, and could lead to different shades of color. Thorough mixing is particularly important when the colors of the sand and cement are different. If streaking is a problem, dry cement and pigment should be thoroughly blended before adding them to the mix.
