2.2.2 Encapsulation or “Wrapping” and Auxiliary Effects
In daily life we use many materials which are made from bound, harmful substances. For instance, a lead crystal glass with high lead content.
When such a glass is used or when a glass breaks the lead is not released because the lead particles are enclosed in the crystalline structure – they are “wrapped” in the crystal fibers.
In a similar manner RoadCem and other PowerCem Technology products are capable of encapsulation of dangerous and toxic substances and keeping the contaminated substances out of the environment as well as preventing their release into the environment.
The “wrapping” and encapsulation of polluting substances into crystalline structure which is a product of hydration reactions of RoadCem improved cement creates a strong and stable material which has structural qualities that we desire in road construction, i.e., high compressive strength, high flexural strength and high breaking strength for example.
Figure 2.10 Why is Lead Crystal not harmful to human health when Lead is highly Toxic.
Figure 2.11 shows a slab that has been made from sludge using Cement and RoadCem. It does not break even under the weight of a hydraulic crane.
