It is difficult to imagine at least one city erected without the use of concrete. What is there a city, at least one house! This material has been helping a person to equip a home for several millennia, simplify work, increase safety and comfort. Today, concrete is in demand in all areas of construction: civil, industrial, military.
To solve various problems, different compounds of concrete mix are used. The standard and easiest composition includes water, cement and sand (gravel). This is the so -called solvent, base and filler. If when pouring monolithic walls, the builder needs the concrete to grasp as later as possible — a hardening deceter is added to the concrete. There are many types of such additives:
Hardening regulators — those same slowdowns and accelerators. Slow down are needed to ensure the integrity of the finished product when pouring large and complex objects. Accelerators — so that the mixture grabs before it begins to settle and lose shape (for example, when pouring arched arches);
Plasticizers and superplastifiers — as the name can be seen, they make the mixture more plastic, flexible, elastic. As a result, its strength increases;
Coloring pigments — simply stain concrete in the desired color;
Reinforcing components: metal pins, rods, grilles. They make the concrete product strong and persistent to the effects of natural phenomena;
Antimorosis additives facilitate the pouring of concrete in the cold season, make the mixture resistant to the effects of a negative temperature;
Waterproofing components significantly reduce moisture on concrete. The presence of these additives allows you to build buildings near water structures or groundwater;
Air -winning substances facilitate concrete, increase resistance to natural factors. The presence of these components requires artificial enhancement of concrete strength, since the mixture becomes more porous and fragile.
In addition, there are a lot of various concrete mixtures on the construction market, which differ in the type of filler, binder or base. For example, asphalt concrete is a mixture of bitumen, sand, crushed stone and mineral powder. And the plaster plate consists of construction gypsum, stone, crushed stone and straw. They have completely different properties, a way of filling and operating. Nevertheless, all this is concrete.
Fortunately, people far from all this, in civilian construction, uses a fairly narrow range of concrete mixtures. When erecting a house, a person most likely needs concrete of brands M200 and m300. For private purposes, you can buy concrete with delivery. The price of the service will be the lower, the closer the concrete manufacturer or the base of the wholesale supplier is. For example, if you need to order concrete delivery in Podolsk, then you should immediately pay attention to local suppliers — it is likely that their price will be the most attractive.
