If you want to make your own white mortar, you'll need the right ingredients. To get true white mortar, you must mix white cement with white sand. Once you have the ingredients in place, make safety your next concern. Cement looks harmless but is very caustic. Protect your skin and lungs, while you work, to stay safe during this big job.
What is silica? Silica may just be one of the most overlooked minerals in terms of health benefits. Silica is most commonly found in nature as sand or quartz. In the human body, this chemical compound is what holds us together as it its a key element in the formation of collagen.
Why is Silica Hazardous? Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction and oil gas sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials.

Silica sand is also used to repair greens and to facilitate everyday maintenance like root aeration and fertilization. The natural grain shape and controlled particle size distribution of silica provides the required permeability and compaction properties for drainage, healthy plant growth, and stability.

Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc., Nonoccupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as nonindustrial sources.
Silica fume's benefits are already evident in the fresh concrete state before it begins to harden. Its small particle size which is 100 times finer than ordinary portland cement complements the finess modulus of concrete and provides a ballbearing effect, which improves thixotropic behavior, in effect modifying concrete viscosity.
