Micro silica

Dear friends and colleagues, Hello
The first phase of the residential town "Entrepreneurs Town" with an area of 78000 square meters (364 x 215 meters) located in BULGARIA - VARNA - KICHEVO - Plot No:052200 with sea view by the Bulgarian company ZEVEZDABUILDING CO. It is about to be built, we are interested in the participation of investors.
Minimum investment amount: 500 thousand euros
Maximum investment amount: 2.5 million euros
The first phase of the desired site has an area with an average width of about 364 meters and a length of about 215 meters
It is about 78,000 square meters in the Kiche Vo-Varna region, which has a north-south direction.
Its eastern edge is about 5 kilometers from the Black Sea, and its southern edge is 5 kilometers from the city center
and it is about 100 meters above the level of the Black Sea, and the main coastal road of the sea with a width of 20 meters crosses the north of the settlement.

With the addition of "microsilica" to "concrete", the free "calcium hydroxide" of the cement paste reacts with the microsilica, producing additional "calcium hydrate silicate" in the cavities between the cement particles and increasing the number of solid structures (CSH) in the cement paste. And the "mechanical strength" of the concrete increases and the "permeability" of the concrete decreases.

Very fine particles of "micro silica" (particles about 100 times smaller in diameter than cement particles) and the occurrence of "pozzolanic reactions" between "micro silica" and "free calcium hydroxide" of cement paste and "hydration reactions" of cement and water, lead to Production of "calcium silicate hydrates (CSH)" and "calcium hydroxide" (CH) or "lime" are released into the cement paste.

Micro silica powder (silica foam) is a by-product of high purity quartz thermal reactions and carbonaceous compounds in arc furnaces.
