Protect the surface of the concrete floor
To protect the concrete floor, which is operated in the normal mode, or is subject to wear in areas with high traffic, there are several ways to protect the surface.
   Comparable ways: their cost, appearance and ability to perform the task to protect.
   In this article, we consider three ways to finish and protect the floor. Each of them has its advantages and disadvantages.
   Thin fil...

Finishing compositions based on water glass. Part 3
When used as part of exhaustion moderator comes coagulation and solidification of liquid glass. However, due to the presence in the composition of Portland cement with a finishing time is an increase strength of the coating due to hydration of cement minerals. Thus from colloids formed during the coagulation liquid glass are actively assigned to the water for hydration of cement, a porous media formed tumors filled Portland cement, which leads to...

Studies in Berlin Institute Federal institute for Materials Research and Testing, show that the average density of 1730 kg/m3 brick large proportion of pores having a size in excess of 1 micron is more than 90% [3] and they are responsible for the increased migration of fluids through brickwork.
   Most fully meet these requirements structure obtained by coagulation and water-soluble potassium silicate forming silica with a high sp...

In the center of Moscow can distinguish vertical structure comprising a crashing into the Earth`s crust magma elongated cylinder (Fig. 2) [5]. In the center section marked lack of extensive vertical zone converted waves ("blind spot"), going from the depths of 70-80 km to 7.5 km. Such "blind spots" are characteristic of the earth`s crust with the introduction of monolithic dense mantle rocks such as gabbro, diabase, etc. In such a zone Tashkent e...

The quality of the decoration of buildings for new construction and reconstruction depend not only on their aesthetic, but also the operational parameters, as good-quality finish - a guarantee of durable service basic designs, long maintenance-free operation, the costs for maintenance and care. Traditional binders used for the production of finishing compositions, liquid glass is widely used, but it has some drawback: coatings based on it gaining...

On possible amendments to the equation Griffiths
Griffith presented a picture of destruction allowed to formulate the problem of determining conditions of the beginning of crack propagation and find its general solution.
   As seen from the above schemes, in the process of crack propagation material directly adjacent to it "coasts" unloaded relaxes. This means that the stress and strain it decreases, and the elastic energy stored earlier in this area of ​​the body is re...

 KALMATRON  for  protection  of  concrete  and  other  capillary-porous  construction  materials  from  water  permeability,  climate  and  man-made  forms  of  corrosion

Protective structure KALMATRON and its modifications are a system of protection of capillary-porous materials of buildings and structures of permeability, climatic and anthropogenic forms of corrosion.
   Composition KALMATRON can be used to protect not only new construction or buildings, but also for objects lost their performance.
   Unlike similar diversion and protective compounds PENETRON SIKA, KALMATRON is a fairly simple application technology, unpretentious to the conditions of storage and transport, which is the result of a new approach to the assessment of environment and interaction design.
   Concrete protection system KALMATRON is a polyphasic conglomerate sparingly amorphous-crystal growths in the diffusion layer of protective and protected concrete, formed by reactions relay-exchange-type insertion between the active chemical additives and low inertia of protective chemicals protected concrete.
   Protective structure KALMATRON comes in four-layer paper bags of 25 pounds, however, upon request, other options are possible packing and packing.
   KALMATRON is non-toxic, fire-and explosion-proof and refers to the danger class 3 (as well as ordinary cement).
   Conducted tests of protective KALMATRON revealed the possibility of its use in buildings drinking water supply (hygienic certificate number issued Moscow City Center of State Sanitary and Epidemiological Surveillance).
   KALMATRON is a cementitious material capillary action, which provides water resistance of concrete, cement-sand mortar, bricks and other capillary-porous materials.
   Effect of waterproof material is provided by a series of strict sequential reactions, continuing in time, extending inside the protected material structure between its components, and components contained in the solution composition KALMATRON .
   As a result of these chemical reactions, it is difficult and poorly soluble tumor that fill the capillaries, pores and microcracks, displacing water.
   Chemical composition of tumors results in high waterproofing properties of KALMATRON due to the increased density of the tumors.
   In addition, due to the formation of hydrated compounds at the interface of the protected material and the external environment is achieved independence chemical characteristics of the environment on the properties of the contact material building structure, in other words - sanitary and ecological environment protection contact. This is especially important when using a protective composition KALMATRON installations in domestic and drinking purposes.
   Scientifically developed formula chemically active part of KALMATRON allows you to make the educational process polyphase conglomerate in the diffusion layer relay character that provides the effect of "self-healing" by blocking the pores and cracks in the layer of protective KALMATRON crystallohydrates.
   Due to successfully develop a set of reactive components protective composition KALMATRON has an extensive range of applications, from the stage of design and manufacturing until the elimination of the emergency condition of the building or structure.
   One of the main purpose of the protective composition KALMATRON is to restore watertight structures. In this region, the protective composition can be used for:
   creating a waterproof coatings (roofs, garages and other facilities) for both new and waterproof for lost objects during operation, while the protective layer can be applied on the outside of the building, and inside.
   creating a waterproofing surfaces (walls of the houses, basements, floors, and other technical facilities) both during construction and during operation, the protective layer can be applied on the outside of the building and inside;
   the creation of protective surfaces, protecting material of buildings and structures in danger of exposure to pressure gidrosredy or in contact with aggressive substances;
   Elimination of strong leaks in basements of buildings, concrete tanks, tunnels and other similar facilities;
   restoration of water resistance and strength characteristics of bridge piers, building block, rubble and rubble concrete foundations by filling internal cavities;
   reduction (increase) frost designs.
   In addition to recovering waterproof and frost protective compounds KALMATRON can be used to improve the strength characteristics of materials. In this connection, it is recommended when:
   sealing of macro-and micro-cracks in structures arising during transportation, installation and operation;
   increase (recovery) of the bearing capacity of structures.
