Protection of Building Constructions with Sulfur Impregnating Solution

Protection of Building Constructions with Sulfur Impregnating Solution A new kind of impregnation compound has been created on the basis of long-term studies in the sphere of durability increase for porous construction materials (cement concrete, lime-sand brick, and autoclave aerocrete) by reducing water absorption through impregnation. The compound is sulfur-containing water solution, stabilized with special additives. High penetrability and molecule size of the impregnation compound (less than 0.5 nm) provide penetration of the solution into 1-10⁴ nm radius pores. The impregnation is carried out by immersing the items into the impregnation compound for 0.5-6.0 hours or by repetitive brushing. The depth of impregnation compound penetration into material structure is 15-40 mm. Treatment with impregnation solution results in hydrophobic coating formed on the surface, consisting of nanosize sulfur particles, with strong adhesion to any nonorganic surfaces. The composition that is not washed away with water, possesses bactericidal properties. Impregnated with sulfur-containing compound building materials have low water absorption, retain low vapour permeability, possess high freeze resistance and durability under atmospheric impact, which allows protecting building units and constructions for a long period of time. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Study of Civil Engineering and Architecture Science and Engineering Publishing Company

Abstract

A new kind of impregnation compound has been created on the basis of long-term studies in the sphere of durability increase for porous construction materials (cement concrete, lime-sand brick, and autoclave aerocrete) by reducing water absorption through impregnation. The compound is sulfur-containing water solution, stabilized with special additives. High penetrability and molecule size of the impregnation compound (less than 0.5 nm) provide penetration of the solution into 1-10⁴ nm radius pores. The impregnation is carried out by immersing the items into the impregnation compound for 0.5-6.0 hours or by repetitive brushing. The depth of impregnation compound penetration into material structure is 15-40 mm. Treatment with impregnation solution results in hydrophobic coating formed on the surface, consisting of nanosize sulfur particles, with strong adhesion to any nonorganic surfaces. The composition that is not washed away with water, possesses bactericidal properties. Impregnated with sulfur-containing compound building materials have low water absorption, retain low vapour permeability, possess high freeze resistance and durability under atmospheric impact, which allows protecting building units and constructions for a long period of time.
