Abstract: This article aims to analyze and present the various uses and protections of biochemically modified silicate in increasing the lifetime of reinforced concrete structures. The biochemically modified silicate is associated with the free calcium of concrete Every time it comes into contact with moisture, reacts chemically resulting in the formation of a C-S-H gel inside the concrete. y expanding seals empty pores and capillaries inside the structure, protecting it and acting on the mechanism of several pathological manifestations that requires the free calcium of the concrete to occur. By incorporating into the reinforced concrete structure, biochemically modified silicate provides definitive (self-healing) regenerative properties to the structure henever it comes into contact with moisture the chemical reaction within the concrete causes the C-S-H gel form expand as the structure needs ts reaction follows porosity and cracking of the structure, filling the necessary voids for protection of the concrete structure and acting on one of the main factors generating pathological manifestations in the structure, the free calcium. The increase in the lifetime of the structure, its protection against the main pathological manifestations in concrete structures and the sustainability that this system has provided for more than 40 years in the world market for reinforced concrete structures are pillars the contribution of the development of good technique in Brazilian engineering.
