White cement

Alexey Tyurin Technology development - the process of inevitable and interesting. With the advent of something new soon appear many possible solutions, improvements, unexpected insights. And if you ask a question about the appearance of innovations, for example, an interior designer, you probably get a detailed response on the use of certain material, but in a very unusual quality. Well, that stalwart building materials manufacturers, builders, designers and decorators take us further away from the grayness and anonymity, and opens up a world of unlimited possibilities for the development and implementation of the unusual architectural form, the interior. Changes related to even a routine and scarce materials like cement. In reality, many types of cement - from the ordinary to special, each of which there is verified the optimal formula for determining its quality. But it is changing and what's interesting, often for aesthetic reasons - there is a white cement that has been successfully used for the manufacture of artificial stone, brick, decorative elements such as moldings and is a part of high-quality glue mortar, making the white and colored concrete, self-leveling device floors and surfaces terrazitovyh, manufacture of small architectural forms, stairs and balconies. With the use of white cement making stairs, curbs and paving blocks. In fact, the list goes on. White cement in front of a gray has several advantages: high compressive strength at early and optimal timing of hardening. Daily strength of white cement about 19 MPa (depending on the manufacturer) determine that the product is fast curing, degree of whiteness (a standard 96,3%), which is determined by three grades: I grade - 80%, II grade - 75-77%, III - 71 -74%; sulphate, low in the alkaline (less than 5%) and frost resistance. The composition of white cement include: brick, diatomaceous earth, inert mineral supplements or mineral pigment. Brand of white cement 300, 400, 500. As is well known cement-based ready-mixed concrete. Of white cement to obtain high quality concrete products, of which create a ready-made facade elements of any desired shape. Products made of white concrete have increased durability, they do not require further processing - their surface is smooth, white and decorative. With further use of the product of the white concrete does not crumble, do not shrink and possibly their wash water. Experts give advice on dealing with white cement: white cement content of not less than 350 kg per m3, a placeholder for the white concrete (fractions 0-2 mm) is taken, just white. absolutely ruled out the presence of a mixture of dust, clay inclusions; tank mixing, mixers, other tools needed to work with white concrete must be clean, not have the presence of rust stains, grease, formwork and concrete form to use clean, causing staining of concrete; in the process of mixing the white of concrete to use only clean water, and if the design of steel reinforcement is present, a layer of concrete on it should not be less than 3 cm "Clean" the color of white cement provides qualitative colorimetric characterization of colored concrete and mixes. Add a coloring pigment in an ideally prepared composition ensures the correct mix of color tone and avoids unexpected surprises violation of shade. In addition, the color preparations based on white cement requires less coloring pigment. An interesting solution is to paint the cement-colored base material, and more creative approach - a game of contrasts. The composition of the white cement is added a marble or granite crumb and get a surface with the effect of "terrazzo" - an imitation of natural stone. White cement - model material for the production bases of high-quality adhesive and grout mixtures. The most well-known manufacturers of white cement HOLCIM (Slovakia), CIMSA (Turkey), JK White Cement Works (India), JSC "Shchurovsky cement. The leader is the same production plant Aalborg White (Denmark), which has the most advanced technology of manufacturing white cement. This is explained by the use of clean raw material base: white limestone from the quarry Aalborg, Northern Jutland sand, many years, washable sea. White Aalborg White cement is exported to more than 70 countries, based on it prepared soy formula "Craps" and "MC-Bauch-Rush."
