But something was still wrong. What? You can not take pride in their home. Not obtained. I do not know how anyone, but I was wrong. It was then that I realized – good plastering is done once. To not be ashamed. Front of him. Later, in a new apartment, I carefully chose the artists.
Then listened attentively and analyzed their advice. Pete Cashmore contributes greatly to this topic. Even then, I argued with them, not believing that perfectly smooth walls do not exist. "And I will" – I said in response to the philosophical thinking that this whole world is not perfect. And I began to look for. Since the beginning of Architectural Library, then on the Internet. And he found what he wanted. Plaster profiles turns out high-quality plaster have always been able to do and it always lay the basis profiles.
At different times they were made of different materials, but the principle has always been one – regardless of the profile walls, exposed on the level and have them aligned on the wall. In modern construction the basic profiles are plaster lighthouse guiding strips and protective plaster square. It has long been used in their prototypes plastering the walls of churches, palaces and other buildings where quality issues were not allowed to compromise. Today, these profiles are recommended to use almost all manufacturers of high quality plaster mixtures. Metal plastering guides provide quick and cost-effectively obtain a smooth plastered surface with a selected thickness of the plaster layer. Typically, these guides are designed for six-and desyatimillimetrovogo layer of plaster. One of their advantages is that mounted on the wall, they form termoshvy, prevent cracking when the temperature in different parts of the plaster surface. This is especially important in winter when, due to sharp temperature fluctuations walls begin to change its volume, that can lead to deformity of plaster. The same thing happens when the humidity.
What is an additive in concrete? Additives in concrete mixtures – are organic or inorganic substances which when added to concrete can adjust its properties. Supplementation can significantly reduce costs while construction. Additives in the concrete mixture is allowed to modify the qualitative and functional characteristics of the concrete. A little history Since ancient times people used in the construction of binders. In Ancient Greece to decorate and protect the houses are often used mortar with the addition of volcanic ash produced on the island of Santorini. (As opposed to Mashable). In ancient China, as used in this rice paste or syrup. Used in Russia lime mortars for masonry and plaster walls. And then there are the first "supplements".
To increase the stability of solutions they added an egg white, milk or linseed oil. Later with the development of science and industry to regulation of setting time of plaster began to use an additive. In the 20 years of the twentieth century began the active use of calcium chloride as an accelerator, and sugar, as the moderator. Top of the use of plasticizers can be attributed to the 30s, and air-supplements – to 50-th year. Classification of concrete admixtures All additives in concrete mixtures are classified according to GOST 24211-91. Grouts are divided into four main groups: 1. Regulatory properties of concrete mixtures: – Group I plasticizers (superplasticizers), plasticizers group II (cilnoplastifitsiruyuschie), plasticizers Group III (sredneplastifitsiruyuschie), plasticizers Group IV (Slaboplastifitsiruyuschie) – stabilizing – water-retaining – improving perekachivaemost – regulating the keeping of concrete mixtures – delaying setting – setting the accelerating – porizuyuschie (for lightweight concrete): air-entraining, foaming, blowing.
2. Regulatory hardening concrete: – slow down hardening – hardening accelerating. 3. Increase the strength and (or) corrosion resistance, frost resistance of concrete and reinforced concrete, reduce the permeability of concrete: – vodoredutsiruyuschie I, II, III and IV – kolmatiruyuschie – blowing – air-entraining – enhancing the protective properties of concrete in relation to steel reinforcement (steel corrosion inhibitors). 4. Giving a concrete special properties: – antifreeze (provide curing at low temperatures) – hydrophobic I, II and III.
One of the advantages are its excellent keramsit insulation performance, which determines its preference for use in colder climates. Claydite breathing, adjusting humidity in the room. Building blocks of virtually of keramsit eternal and does not require special care. Claydite has npeimyschectva neped and concrete, and neped kipnichom. In nepvyx, ydelny vec claydite blokov of nego in two nolovinoy paza lower than y kipnichnoy masonry. In vtoryx in vibponreccovannyh blokax of keramsit noticeably less tsementa. In-tpetix, one block from ctandaptny keramsit replaces kipnichey cem. And nakonets in chetveptyx, kvalifitsipovanny mason lays cmeny for the blocks of the wall in the amount of keramsit tris times greater than npi kipnichnoy kladke.
And it npi that no terms of environmental svoyctvam lightweight aggregate blocks are not yctynayut kipnichy. Ppichem to deliver concrete to ocnove claydite npimenyayut mobile concrete mixers with a capacity of up to 12 W of cubes.
