Specifications and properties of cement

  1. SSPTs 500-D20 Sulfate-resistant Portland cement is one of the types of Portland cement, and is resistant to sulfate waters. Ordinary groundwater contains a lot of sulfates, they contribute to the destruction of concrete. To protect concrete structures from such impact, the SSPC is used.

  2. PC 500-D0 The most popular brand of cement. Almost all manufacturers of cement plants have this type of cement. Sellers have a very popular (basic) unit of cement products in stock. Tkoy cement is very well suited for concrete work.

Portland cement production technology

Portland cement is a hydraulic binder that hardens in water and in air and is a product of the finest grinding of clinker obtained by firing an artificial raw mix to sinter.
The production of Portland cement includes the following stages: extraction of raw materials; preparation and preparation of raw mix; roasting of the prepared raw mixture and, as a result, obtaining clinker; joint grinding of clinker with gypsum, and in some cases with various additives capable of imparting special properties to Portland cement, the first three stages being the most energy-intensive and expensive, they account for about 70% of the cost of cement.

In the production of Portland cement, it is necessary to combine carbonate and clay components in the raw mixture, which are contained in different proportions in marl – a rock that makes up the slopes of the Markkhot Range. In addition to the main materials in the production of Portland cement, various corrective additives (iron-containing, aluminate, etc.) are also used.
The extraction of marl is carried out by an open method in quarries. Marl quarries are developed by horizontal ledges from 15 to 20 m high. The main processes in the extraction and processing of marl are stripping, destruction and extraction of material, loading by excavators and intra-quarry transportation by mining trucks. Marl from the quarry enters the crushing department, where it is subjected to one or two-stage crushing in jaw, impact – reflective, hammer crushers. Crushed marl is delivered to the warehouse through a system of conveyors.

There are two main methods for the production of Portland cement – “wet” and “dry”. In the “wet” method of production, raw materials are crushed in grinding plants in the presence of water, resulting in a flowing creamy mass, called sludge, with a moisture content of 37 – 38%. The raw mixture obtained in this way is fed for firing into a long rotary kiln with internal heat exchangers.
Dimensions of rotary kilns for wet production: Ø5x185m; Ø4x150m; Ø4×3.6x4x150m.

The “wet” production furnace can be divided into 6 technological zones: drying, heating, calcining (decarbonization), exothermic reactions, sintering and cooling. In a rotary kiln, under the influence of high temperature (1450 ° C), the raw mixture undergoes physical and chemical transformations, resulting in clinker, which is gray solid granules with a diameter of 5 to 20 mm.

With the “dry” method of production, grinding of raw materials is carried out with simultaneous drying, resulting in raw meal with a moisture content of not more than 1%, which is fed for firing into a short rotary kiln with furnace heat exchangers: cyclone heat exchangers and a calciner.

Dimensions of rotary kilns of the “dry” production method: Ø5.5x66m; Ø 5.2x65m. There are no drying zones in the rotary kiln of the “dry” production method, the remaining zones and the processes occurring in them are similar to those of the “wet” method kiln. The processes of dehydration and almost completely – decarbonization of the raw mixture occur in cyclone heat exchangers and a calciner, from where the raw mixture enters a short rotary kiln.

There is also a combined method for the production of Portland cement, which involves either partial dehydration of the sludge (up to 16-18%) using vacuum filters and sludge concentrators, or moistening of the raw meal to a moisture content of 10-14%, granulation of the raw mixture and feeding it for firing in a short rotary kiln.

When choosing a production method, various factors are taken into account: the uniformity of the chemical composition of raw materials, their physical and mechanical characteristics.

Currently, the “dry” method of cement production is most in demand, as it is more economical: the specific consumption of standard fuel per 1 ton of clinker with the “dry” production method is two times less than the specific consumption of standard fuel with the “wet” production method.


Fuel economy is a decisive argument in favor of the “dry” method of production, since one of the largest cost items in the production of Portland cement is the consumption of standard fuel for burning clinker.
Portland cement clinker obtained by one of the methods, after cooling, enters the warehouse of clinker and additives.

To obtain Portland cement, clinker is subjected to fine grinding in mill units together with gypsum (used to regulate the setting time of cement paste), as well as in the production of some types of cement – with various additives.
Ready-made cement is transported through a system of cement pipelines for storage into specially equipped silos, from where it is shipped to the consumer in containers or in bulk into wagons – cement trucks or trucks
