Mortar, Concrete

Today, the demand for real estate, whether commercial or private, is increasing every day. And consequently, the need for building materials is increasing, in the series of which, of course, concrete solutions, various additives to concrete, dry mixtures and, of course, solutions, are included.

So, mortar for laying stone can ensure the solidity of bonding clinker or stone when laying. Building polymer-cement mortars have in their mix these ingredients: water (better filtered), binder (alabaster, cement or lime) and aggregate (this is often sand and gravel). As a rule, in such mixtures (for brickwork), the proportion of sand and lime is 1: 3 or 1: 4. This mixture of builders is attributed to the first solution group (WG I). And when you add a few shovels of cement to this mixture (for example, with a volume of 80 liters), in this case you will get a mixture of the second solution group - WGII. To build bearing structures or bases, a cement-sand mixture is used, which is used on construction sites more often than others, and the proportion of constituent components is: one unit of sand: three units of a cementing element or one part of sand: six parts of cement.

Also often used plaster solution. It consists of one unit of lime and three parts of sand - this is for outdoor work. As regards internal works, the correlation of the constituent components is somewhat different - one unit of lime to five parts of sand. Cement mix for plaster is no less popular than cement-sand for foundation, and contains the following composition: the proportion of sand and cement is 1: 3. Now a wide variety of additives are used in cement mortar in order to improve mechanical and physical properties. With regard to gypsum as an astringent element, it stiffens by the way of crystallization itself, without the participation of any additives.

When grasping the cubature of the mixture rises, so that this does not happen, add a little sand - one part to two parts of the gypsum. By the ratio between the amount of binder and aggregate, there are distinguished fatty, ordinary and lean solution mixtures. Fatty - flexible mixtures, however they make a considerable shrinkage when hardening, and if applied in a thick layer - they are covered with cracks. Skinny have a relatively small amount of binder, and, on the contrary, they give very little shrinkage, this is especially appreciated when facing.

In case you want to give your home a unique color, then choose your choice on multi-colored mortar solutions. In particular, selected in the tone of the facing material, the masonry mixture makes it possible to make seams invisible. The mortar is a fine-grained mixture, which is carefully measured, and consists of an inorganic material, a small amount of water and a filler of small fractions. It is used for finishing interior and exterior work, and also for laying brick and stone walls. There are a number of types of solutions: waterproofing - a combination of cement, in which are added ceresite, ferric chloride and sodium aluminate; Cherezit - a mixture of white, which is obtained as a result of combining amyl acid, lime and ammonia; Masonry - a mixture of cement and lime, or from cement and clay; Plaster - it includes dusty sand for an ideally smooth wall covering; Cement - a mixture of cement, sand and water. Depending on the brand of solution, the ratio of these constituent elements may be different. Now manufacturers sell ready mixes of the most various shades that are placed in bags of 10, 15, 25 and 1000 kg. Multicolored masonry solutions have a number of advantages over ordinary concrete:

1) free choice of color; 2) hardens for a couple of hours; 3) relatively low price.
